In the mobile device environment, the context-aware computing has been emerging as a core technology of ubiquitous computing. Compared with a desktop computer, a user interface and resource of mobile device is very limited. Traditional desktop-based user interface has been developed on the basis that a user's activity is static state. In contrast, mobile devices are not able to utilize representative desktop-based interaction mechanisms such as a keyboard and mouse, not only because the activity of a user is dynamic state, but mobile devices have limited resources and small LCD display. In this paper, we introduce an intelligent control system for the mobile device that can utility effectively the limited resource and complement the poor user interface by using an accelerometer being able to sense the physical activity and posture. The proposed system can estimate the user activity, static and dynamic states, and posture watching the PDA at the same time, and the proposed intelligent control system as its application, the backlight ON/OFF on the PDA, is run by the result of the user's behavior.

RFID technology enables companies to precisely manage their inventories at the item level. Recently, due to the wide spread of RFID data-exchange standards, RFID systems are being recognized as separate information systems, each of which is consist of RFID hardwares, a middleware and data repositories, thereby RFID systems become common targets for system integration. In this paper, we proposed an effective integration framework between RFID systems and existing enterprise information systems (EIS). We also surveyed the current state of the RFID-EIS system integration practices. The proposed framework will be helpful for system developers to effectively integrate RFID systems with EIS's.

The current software development type is based on CBD (Component Based Development). However, it requires a new component model that can support rapid and accurate component information on the web due to the cost increase of building new components using CBD. The purposed of this paper is to promptly develop an application on the web which fulfills users' demand and to provide specific interface regarding the small scales of distributed component in business domains. The e-BCOS(e-Business Component System) is the agent system for the users to register distributed components and to search component information, which would increase reusability through the e-business component development of distributed components in business domains and help the users understand the information about the component. Moreover, XML is employed for specification which allows smooth specification sharing and delivery to satisfy users' variable demands.

The challenges facing manufacturing companies today span across the industry, independent of company size or product. Especially, big manufacturers must overcome these challenges, and information technology (IT) collaboration with small and medium enterprises (SMEs) will play a major role in this effort. In this research, the strategy and way to promote IT collaboration between SMEs and large firms in heavy industries are proposed. A pre-consultation was performed to derive the strategy and way for the collaboration, and an IT collaboration system was developed reflection the results of pre-consultation. The IT collaboration system consists of two parts. One is ERP based on BPM for SMEs to standardize and visualize the entire business process from order placement to release. This system also provides their parent company with visibility into the status of orders and user can easily access the system on the web at a low price through cloud computing service. The other is interface part for data changes between large firms and SMEs. Thus far, this paper demonstrates the importance of strategy for the collaboration, and the applicability of IT collaboration system to elevate the speed and efficiency of business.

During the early stage of radioactive disposal programs, important issues related with quality assurance of data sets, methodologies, R&D procedures are recognized as important ones. This paper focused on the development of web-based workflow standards for the QA procedures of the radioactive waste disposal programs. The flow of process was analyzed based on workflow concepts proposed by the Workflow Management Coalition (WfMC). QA system is based on the principles of T2R3. T2R3 Workflow was used to standardize and restructure the business and/or work process in the industry or organization. The WfMC has identified five functional interfaces to a workflow service as part of its standardization program. They are composed of process definition interface, worklist handler, application program interface, interface between workflows, and system management. The task flow and QA program were defined based on the workflow ideas. QA procedures for the R&D results of radiation disoposal were analyzed following the reference model of workflow. In addition, six program run list were created and implemented. The creation, revision, and approval of the test data were designed to be inplemented on the web environment. Through this system, R&D procedures such as planning, research, documentation, internal review and future independent peer review processes could be well organized and stored more systematically on the database and knowledge base. This will encourage the usage and data sharing between interested parties through it's clear and transparent workflow standards.

Purpose This paper attempts to identify items for improving the usage of PLM(Product Lifecycle Management) systems and suggests ways to prioritize improvement items on the basis of importance. It also tries to find out differences in the importance of improvement items due to the company size, the industry, the job, or the PLM solution. Design/methodology/approach Through a survey from participants to a PLM System Conference, data were collected from a sample of 181 users who had the previous experience in using a PLM system. In order to figure out the differences in the importance among user groups, the F-test with the Scheffe test as a post-hoc analysis was used in case of equal variances and the Welch test with the Dunnett T3 test was used in case of unequal variances. Findings This study sorted out 25 improvement ideas according to their importance assessed by the PLM system users. The top five ideas are improving data consistency, error minimization, fast system response time, enhancing user recognition, and business process improvement. The support group puts higher importance than the general user group in data consistency, fast system response time, enhancing user recognition, business process improvement, dedicated team for data consistency, continuous support from management, hardware performance upgrade, output linkage to other systems, and shortening problem solving duration. The largest company group attaches significantly higher weights than the smallest company group to data consistency, error minimization, fast system response time, business process improvement, dedicated team for data consistency, security with proper access management, output linkage to other systems, and better user interface.

In CALS/EC environment, there are geographically dispersed heterogeneous databases and various applications. Integrated database environment provides transparent access mechanism for heterogeneous and distributed databases and interoperability between applications in various platforms. Because elements exist geographically in integrated database environment, directory service is necessary for providing unique access mechanism for elements. In this paper, we design a directory service using CORBA based access interface and object-oriented DIB model for accessing transparently to elements and interoperability with other information system.

The scope of e-Commerce process becomes wider as the emphasis on the enterprise collaboration grows. It has expanded from its initial settings of order management or billing processes to cover various collaborative processes in the company's value-chain. In order for those collaborative e-Commerce processes to be successful, corresponding business processes should be fully supported by standard bodies. The RosettaNet consortium, one of the most representative international B2B standard bodies, has steadily provided new PIPs to support those expansions. Since individual RosettaNet PIPs correspond to unit tasks that are executed separately in or between companies, multiple PIPs have to be integrally used to properly handle larger business cases. RosettaNet implementation, however, has suffered from the lack of standard guidelines or deliverables to refer under this multi-PIP environment. In this research, a contents-based document routing system is implemented. By applying this routing system to the RosettaNet e-Logistics program where multi-PIP environment is inevitable, we verified our contents-based document routing system is effective to support multi-PIP environment flexibly.

The Web-based project is seriously not efficient area at software engineering. In order to develop a Web-based system, UI(User Interface) designers usually first design display layout and then business logic developers bring to complete the coding of the display layout source. In the case of maintenance, it goes through the same process. This kinds of Web-based software development method were proposed by the various methods same as the tag library of JSP. But there are many problems to apply them and they are low productive comparing to the C/S based software development method. WFS(Web Form System), which is suggested on this thesis, separates UI design from business logic on a Web project and offers the better environment to develop Web-based software. Eventually WFS will improve the productivity to develop Web-based software.
