Practical use of Information Technology in present enterprise simply enterprise support do pass over known dimension and is utilizing by means for enterprise competitive power strengthening. Because of these point, a lot of kind of information systems appeared. It can be said that EIP system that many enterprises are introducing recently is concept that appear to also use information in enterprise more efficiently. If present EIP system sees construct example, segment is detected to improve some. First, should do duplicate development despite it is same function to use EIP system in wireless and web browser environment. Second, can hear management's difficulty by immense contents that happen in System Integration. We wish to solve problem that happen in development of existing EIP system using XUL and a SVG technology in this paper that aim to these. XUL is open source In language to manufacture UI that do not receive court of platform and existence and nonexistence captain rain, support wireless and web browser equipment at the same time to source that is produced once if is browser that can manufacture usable interface in web and supports XUL as user wants. SVG method is a skill that can offer convenience that is epoch-making in contents management by software that describe contents representation in source code unlike form that show because calls contents forming already in the existent bit map room and establishes to browser handles this and expresses contents. In paper, produced use of XUL and SVG by prototype to presented whether can apply XUL and a SVG technology to actuality EIP system and verifies whether this is possible and that do actuality through existent method and comparison and excellency were seen.

To improve the quality of the services and to concentrate on the core capability, in public sector the IT outsourcing is recently being vitalized by the institutional support of the government for the entrusting non-government. Because the lots of general studies so far have simply focused on indicating fragmentary factors i.e. economical factors, risk factors, system factors, or induction objects, etc., they are insufficient in making the practical decisions, therefore we indicated systemized model extending over the whole range of the IT outsourcing to support substantial decision makings, and assorted 4 categories and drew considerable 55 factors from the literature study to materialize the previously considerable factors at each decision making stage. And the principal factors were drawn from each decision making category by a group of 11 experts. Besides, a henceforth plan for the application was also presented through an actual example of the IT outsourcing decision making process of 'M', a public enterprise.

Due to the constant expansion of overseas public IT market, exportation market mainly based on e-government is expanding and platform needs to be introduced urgently to systematically support it. Thus, this study was carried on to draw evaluation items and weighted value of tools to support decision-making out of services of public IT platform. In this study, the tools supporting decision-making were defined as concept that draws exportation customers by wholly considering 2 aspects of enterprise capabilities and national environment. To develop tools supporting decision-making, the items to evaluate the aspect of enterprise capabilities and national environment were drawn through study on literature and open question and evaluation items were eliminated and AHP analysis was done through question given to experts. As a result, the significance was found in the order of Export Competitive Advantage > Export Marketing Strategy > Export Human Resources > Export-Related Organizational Resources > Export-Related Organizational Capabilities in the aspect of enterprise capabilities. The significance of evaluation was found in the order of Service Market Efficiency > Technical innovation and Maturity > Institutions > Market Efficiency > Macroeconomic Environment > Infrastructure in the aspect of national environment.

Many companies in mechanical engineering fields have accumulated information of design and manufacturing. The Enterprise Resource Planning (ERP) and Product Data Management (PDM) systems help information gathering and data managing. However, these systems are not flexible to support suitable functionality for specific product because these systems deal with entire enterprise resources. To cope with this issue, a web-based design support system was constructed for the design process of automotive steel pulley. This system provided 1) search service for part design with key word and clustering map, and 2) estimation service of maximum stress. These services reduced design time by reducing iterative jobs with Computer Aided Design (CAD) and Computer Aided Engineering (CAE) for stress analysis, and by enhancing search for existing data of steel pulley.

As the competitiveness of SMEs (small and medium enterprises) is getting more and more improved and globalized, the government provides various consulting services to secure the competitiveness of small and medium firms and support stable growth. However, the assessment of the result from the government's support is generally focused on non-financial factors, such as customer satisfaction and analysis of improvement effect. This paper is in regards to the statistical analysis of how much the government's support in the form of providing consulting services contributes to financial outcomes in terms of profitability and growth. ROA (return on asset) and ROS (return on sales), which are investment profitability and sales profitability respectively, are chosen as an indicator of profitability. For analysis of growth, sales revenue and total asset growth are used. The samples are 44 corporations which are supported by government, and 150 corporations which are selected for comparison, with corporate growth support center program by the Ministry of Trade, Industry, and Energy chosen as the consulting model. After gathering the yearly balance sheets and income statements of the samples from CRETOP, Korea Enterprise Data, the analysis is conducted in the way of identifying the statistical significance of financial difference in the same period between corporates taking consulting services and corporates which have not, and the difference of financial outcomes from the corporates taking consulting services before and after consulting services. As a result, in terms of business growth, it is turned out to have positive difference both in growth ratio and profitability compared to the compared corporations at the significant level. Therefore, it is obvious that the consulting program which government provides to SMEs have direct influence practically to the corporates' management performance.

As the value of B2B integration gets more importance and the business process becomes more complex, BPEL4WS standard has been focused for the solution of the problems which is based on web service technology. Many vendors implement the standard in their systems to integrate B2B and web service based inner-Enterprise Application(EA)s. But there is no way to use the standard to integrate non-web service based EAs, because the standard is designed only for Service Oriented Architecture (SOA) over web services. This paper proposes Hybrid Service Orchestration Framework to participate web services and also non-web service based EAs in the business process as a partner using BPEL4WS standard. The framework introduces Hybrid Service Architecture to represent non-web service based EAs as a service, so BPEL4WS could be used to integrate web services and non-web service based EAs. And the framework also introduces Hybrid Service Toolkit to support software level facilities. The paper also introduces Hybrid Orchestration System that is based on Hybrid Service Orchestration Framework.

Web services are key applications in business­to-business, business-to-customer, and enterprise applications integration solutions. As the mobile internet becomes one of the main methods for information delivery, mobile Web Services are regarded as a critical aspect of e-business architecture. In this paper, we proposed a mobile Web Services middleware that converts conventional internet services into mobile Web services. We implemented a WSDL (Web Service Description Language) builder that converts HTML/XML into WSDL and a SAOP (Simple Object Access Protocol) message processor that performs SOAP message handling, chain and handling of server requests. The former minimizes the overhead cost of rebuilding mobile Web Services and enables seamless services between wired and wireless internet services. The latter enhances SOAP processing performance by eliminating the Servlet container (Tomcat), a required component of typical Web services implementation. Our main contributions are to overcome the latency problem of current Web Services and to provide an easy mobile Web service implementation. Our system can completely support standard Web Services protocol, minimizing communication overhead, message processing time, and server overload. Finally we compare our empirical results with those of typical Web Services.
