PMO(Project Management Office) has been considered as a general approach for the successful operation of IT project. The previous studies tended to emphasize on the roles and functions of PMO in a normative way. However, in practice, since PMO is operated as a joint structure in which client firms and professional PMOs work together, it seems to be important that the implementation system of PMO should be properly formed. In this paper, it is examined whether the competence of client firms and professional PMO influence on the setup of implementation system of PMO, and also whether implementation system of PMO influence of the performance of IT project. In addition, it is also analyzed if the competence of client firms and professional PMO influence differently on the setup of implementation system of PMO, according to the degree of knowledge complementarity. As a result of this study, it is found that the competence of client firms and professional PMO influence positively on the setup of implementation system of PMO, and governance factors such as clear definition of organizational roles, responsibility, and setup of standardized processes are also important in performance of IT project. It is also shown that, if knowledge complementarity is formed with a common knowledge base between client firms and professional PMOs, Project Management Office functions effectively. In summary, for the successful performance of IT project, it seems that it is required to approach from the view point of governance in forming the implementation system of PMO and it is also important to form knowledge complementarity between client firms and professional PMOs.

The telecommunications of previous years have been utilized for internal usages, but those in current years have widely extended even to usages for Interorganizational Information System(IOIS) beyond its internal uses. Electronic Data Interchange(EDI), a subsidiary form of IOIS which permits interorganizational electronical exchanges of transaction documents through the telecommunications networks between and among computers, is expected to bring forth various innovative results with improved efficiency and productivity through the improvement and simplification of transaction processes, And it became needed and significant to review studies with practical values and necessity. This study is implemented on the basis of a judgement that Korea businesses can improve some of their structural problems of high costs by successfully adopting and implementing EDI system in their organizations. And it's also realized that more studies on the related subjects will benefit and be valuable for various applications. The major objectives of this research is to identify factors influencing in the implementation of EDI system by Korean business entities. Business which already implementation EDI system in their organizations were subjected to the survey. Also, this study intended to identify variables influencing in the implementation of EDI system and further provide directions needed in establishing or managing EDI system.

This paper presents a design and implementation of cyber-school system using object modeling technique and web groupware. The system design method based on object modeling techniques reduce cyber-school construction effort and cost with reusing of modules. The system is a kind of web group application based on WWW that allow members who located on remote computer to do cooperative learning and to communicate with other students and teachers independent of time and location. In this system we use Linux operating system for efficient development on real education field. and we can reduce cyber-school development effort arid cost With this system.

In the modern business environment, ERP System is a tool for efficient use of the resources of the company. Implementation of the ERP System is not a simple introduction of the unit system. The changes and innovation of the company will be made through the BPR. And then, the BPR is made based on the system design and implementation. Cultural difference creates a difference in the attitudes and relationships of members of company. and, Cultural difference produce differences in organizational culture and operating principles. Cultural differences can mention the differences in the cultures of East and West, and can mention the difference between each country within the same culture. In the paper, we determine the impact of cultural differences on the implementation of the ERP System. Cultural differences affect the implementation process and the decision-making process, user interface.

The purpose of this research is to understand, through a case study, how the flexibility of Headquarter(HQ) and subsidiaries makes an effect on performance of global ERP system implementation in a global firm. The questions of this research are as follows. First, what types of flexibility are there for HQ and Subsidiary, respectively, which are related with global ERP system implementation? Second, how much impact do these types of flexibility have on the performance of global ERP system implementation? This research suggests three types of flexibility for HQ and three types of flexibility for subsidiaries that are related with the global ERP system implementation. In this study, BorgWarner, a global automobile parts manufacturer, was selected and analyzed to find out what kinds of flexibility contributed to enhancing its global ERP system implementation performance.

In this paper, we aim to implement the embedded VoIP Phone based on EISC core Microcontroller. EISC is recently new microprocessor architecture, which contains both advantage of RISC and CISC. This advantages are desirably resulted in high code density, high performance and 16/32/64bit scalable instruction length. Also, we select the embedded system which can be guaranteed performance and economical efficiency for implementation that system. As the step of this research, we first study basic system for implementation of target system. Next, we construct the structure of embedded VoIP Phone based on 32bit EISC MCU efficiently. And then we realize that constructed system and verify the performance of that realized system by the test of voice communication in field.

This paper describes the design and implementation of a wireless home network system using Home Network Control Protocol (HNCP) called the wireless HNCP home network system. For wireless interfaces of HNCP, IEEE 802.11b and IEEE 802.15.4 standard protocols are considered. With the implementation of the wireless HNCP home network system, a simple analysis about coexistence between IEEE 802.11b and IEEE 802.15.4 is achieved. Through the implemented wireless HNCP home network system and the analytical results about the coexistence between both two different wireless protocols, the feasibility of the wireless HNCP home network system is shown.

As numerous sensors and actuators are used in many automated systems, various industrial networks are adopted for real-time distributed control. In order to take advantages of the networking, however, the network implementation should be carefully designed to satisfy real-time requirements considering network induced delays. This paper presents an implementation scheme of a networked control system via Profibus-DP network fur real-time distributed control. More specifically, the effect of the network induced delay on the control performance is evaluated on a Profibus-DP testbed. Also, two conventional PID gain tuning methods are slightly modified fur fouling controllers fur the networked control system. With appropriate choices for gains, it is shown that the networked control system can perform almost as well as the traditional control system.
