The recent control system has been changed into the type of PLC(Programmable Logic Controller) control. Up to now, systematic approach of PLC programming or control logic design is not suggested. In this study, the design process of the control logic is systematized and concrete process in each step is suggested. This systematized approach lead developer to be convenient to implement control system. When some error is occurred in the system, this approach enable the developer to analyze the reason of error rapidly and the system is amended according to systematic information of the analysis. The example of control system implementation following this approach is introduced.

The core of the semantic web is ontology, which supports interoperability among semantic web applications and enables developer to reuse and share domain knowledge. It used a variety of fields such as Information Retrieval, E-commerce, Software Engineering, Artificial Intelligence and Bio-informatics. However, the reality is that various errors might be included in conceptual hierarchy when developing ontologies. Therefore, methodologies and supporting tools are essential to help the developer construct suitable ontologies for the given purposes and to detect and analyze errors in order to verify the inconsistency in the ontologies. In this paper we propose a new approach for ontology error detection based on the Concept Lattices of Formal Concept Analysis. By using the tool that we developed in this research, we can extract core elements from the source code of Ontology and then detect some structural errors based on the concept lattices. The results of this research can be helpful for ontology engineers to support error detection and construction of "well-defined" and "good" ontologies.

In this paper, we suggest an XML Development Support(XDS) System as a good developing tool to solve the problems that related with the database integration, increased to the developing terms and costs when the developing of XML programming base on the web server. XDS System is designed for the purpose of easily coding the XML program, of simply changing the programming structure and of completely maintaining the program environment. According to the predefined policy, XDS System provides necessary informations such as tables, columns, or relational keys from Database for developer. The developer step by step selects or sets what he needs. And XDS System creates an XML Tree with the result of selected information. The XML Tree includes all information of making an XML Schema and some XML Stylesheet. XDS System creates an XML Schema for all clients and creates many XML Stylesheets for each client using the XML Tree.

The rapid design of the embedded system is crucial for improving the product’s competitiveness. Existing statechart tools used for designing the embedded system rely on the copy and paste of the statechart for reuse. However, such method has a major drawback of wasting both time and cost of the system developer. This paper implements the component supporting tool. A tool that makes efficient reuse of a statechart by adding a component function to the existing functions is implemented in this paper. Also, to add a component function, this paper restructured the contract as protocol of the inter-component. The implemented tool helps not only reduce the life cycle of a product, but also enhance a product’s competitiveness by supporting the product’s time-to-market.

A performance evaluation tool makes an important role in order to improve performance of an embedded software which has restricted computing resources. However, existing performance evaluation tools for embedded softwares cannot be used in collaborative development environment because they support only one developer with performance evaluation work under cross development environment. In this paper, we propose a performance evaluation tool for embedded softwares on collaborative development environment. A proposed tool is based on server and client model. It can have flexibility in offering and integrating the result information for the items. Through the suggested tool. developers can intuitively understand and analysis performance evaluation results each other.

In this paper, we developed the Distributed Programming Developing Tool(DPDT) which can make distributed application program efficiency based on the distributed object group framework supporting group management and dynamic binding for object resources requested from clients on distributed systems. The distributed object group framework we constructed provides not only the group register/withdraw, the access right and the name/property services for server objects from a point of view of group management services, but also dynamic binding, replicated object supporting, load balance, and federation among the object groups from a point of view of the supporting services of distributed application, When developing distributed application, by using our tool, server programming developer implements objects in each server system, next registers the properties to need for service provision to the object group. Client programming developer can also develop client program easily by obtaining the access right for the object or the object group and using the properties of objects with the access right permitted to the client. For providing above application developing environment in this paper. we described the definition of object group, the architecture of the distributed object group framework which our tool supports, and its functionalities, then specified the 3 GUI environments of DPDT implemented for providing efficient interfaces between the distributed object group and distributed applications. Finally, by using the DPDT, we showed the group register/withdraw and the access right grant procedure of objects which are server programs, the developing process of client program, and the executing results of the distributed application developed.

In component based development, component modeling for understanding and analyzing is the important part and is used to improve reusability. Generally, components are need to be divided into two types according to their usages, where the developer and assembler are usually different. To make a good component model, a complete component and interface specification for those components are needed. And the component model needs to adept two different views of developer and assembler. In this paper, we suggest two different views of component model that is related to views from developer and assembler, and we expand UML. Also we validate the efficiency of the suggested model by developing and applying a tool for building, managing and automatic transformation.

Purpose of this study is studying direction that change of design by development of new digital technology. And with new technology, find direction of architectural design. Digital technology for architectural design demonstrates hightechnology or is not limit. Must recognize change for our idea and necessity. We can know change in relation of photography and impressionism. Idea and hitting on a thought which is arts by new technology changed. Finally, we must develop techniques of design on the basis of technology and look for possibility of new expression. Digital medium expands communication with designer and customer because there is special quality of nonlinearity, interactivity and audiovisuality unlike old medium. Digital medium can take advantage of techniques of new design. Can construct R&D and database of design and improve quality of design. Designer must master use skill to take advantage of digital technology in design. Because quality of design becomes different according to degree that use. Also, developer of digital technology must supply design tool such as previous design method. Creativity that architectural design that allow fetters in digital technology can understand design in new viewpoint is required. Architectural design may be magnified by architectural design that allow fetters in multimedia. We may see experience between new time and space of architectural design and reappearance space reappeared in cyberspace. Architect is going to run role as developer of culture. Value and technology of digital design may offer more more possibility and an opportunity since Intustrial-Revolution.

In this paper, we design and implement a mobile game based on windows phone platform. Visual Studio and the Windows Mobile software development kit(SDK) and developer tool kits (DTK) make it possible to create software for the Windows Mobile platform in Visual C#. Also The XNA Framework is the set of .NET libraries that developers will code against to build games. XNA Framework support PC and XBOX and a ZUNE HD multiplex platform environment and 2D and 3D games provides the necessary functions to a development. XNA Framework is to make it easier to develop games because the codes which are succeeded creates with automatic, implements a game development relation resource and the game logic. The key idea of our game is that we use shooting and ranking system to raise fun.
