This paper describes case studies on workflow impact analyze with an enterprise ontology (EO). We build the EO with an ontology editor $Prot{\acute{e}}g{\acute{e}}$ and integrate concepts of enterprise architecture and a process model into it to expand the EO. We use the expanded EO and Prolog query rules to analysis workflow dependency relations from the perspectives of routing, data and role. Through this, we analyze impact of changes in workflow process. Moreover, we have found the effectiveness of the EO and $Prot{\acute{e}}g{\acute{e}}$ in modeling business management and, in particular, workflow representation and management.

In order to resolve the problems of traditional Enterprise Application Integration (EAI) for system integration and to establish flexible enterprise IT environments, Enterprise Service Bus(ESB) which have distributed architecture and support Service Oriented Architecture(SOA) has introduced. Particularly, JBI which developed by the Java Community Process is most widely used to implement ESB for advantages of Java technology. In ESB based on JBI, reliable message delivery is very important to ensure stability of services and systems because it is a message driven architecture. But, it is difficult to verify messages and trace messages when system fault or service error occurred because JBI specification is not enough to address them. In this paper we has proposed the Message Monitoring Framework for JBI-based ESBs which for using in monitoring messages efficiently. It provides foundations for gathering and tracing message-related information about component installation, message exchange, service deploy by using proxy-based change tracking and delegation mechanism for data processing. The proxy which used in our solutions collects data about message automatically when it changed, and the delegation mechanism provides users flexibility for data processing. Also, we describe the performance evaluation results of our solution which is acceptable. We expect to it enables users to ensure reliability and stability of the JBI-based ESB by systematic monitoring and managing messages being used to interact among components.

Refining the monitoring and evaluation reporting is an important thing in e-Government. Indonesia which has had e-Government roadmap since 2000, has not had the systematic mechanism to monitor and evaluate e-Government in which the report can be easily accessed by the public and used to be the best practice to improve other e-Government implementation. Enterprise architecture (EA) has the major objective to straighten an enterprise to its necessary requirements. It can be used to propose the required system and that was the purpose of this paper. It was started by reviewing the literature about e-Government monitoring and evaluation, using quality of service as the means, and understanding TOGAF as one of EA framework. The second step was comparing EA and the evaluation of e-Government in Korea and Indonesia to get the best practices. And the last step was creating EA for the monitoring and evaluation reporting system based on Korea and the literature reviewed. It is expected that the formulized EA can be a tool to improve e-Government implementation in Indonesia.

Many enterprises have implemented packaged enterprise resource planning (ERP) solutions rather than system development on the promises of feasible strategic benefits. Typical feasible benefits include adoption of global standards and processes through a proven integrated system, continuous version upgrading by vendors, and thus the easiness of system maintenance. The objectives of this research are to identify what makes a post-implementation success of ERP system and to figure out the critical issues and factors for the successful upgrade of packaged ERP systems. This case study was conducted based on five different organizations that have experienced system upgrade implementation. Success factors of ERP system upgrade include (1) clear statement of upgrade goals, (2) good coordination and communication among the implementation partners, (3) thorough management of customization and maintenance history including documentation, (4) Planning of system requirements of higher version, and (5) redefinition of role between business departments and IT department.

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.

According to the development of IT technology, life itself is becoming the change to Knowledge-based systems or information-based systems. However, the development of IT technology, the cyber attack techniques are improving. And DDoS a crisis occurs frequently, such as cyber terrorism has become a major data leakage. In addition, the various paths of attack from malicious code entering information in the system to work for your company for loss and damage to information assets is increasing. In this environment, the need to preserve the organization and users of information assets to perform ongoing inspections risk management processes within the organization should be established. Processes and managerial, technical, and physical systems by establishing an information security management system should be based. Also, we should be introduced information security product for protecting internal assets from the threat of malicious code incoming to inside except system and process establishment. Therefore we proposed enterprise and government information security enhancement scheme through the introduction of information security management system and information security product in this paper.

Generally, because individual agricultural product possesses its own distinctive characteristics and shows different characteristics at each stage of the agricultural supply chain, it is necessary to develop a proper enterprise architecture for managing information system. In this paper, we propose an enterprise architecture based on RFID/USN technology that can be used as a reference enterprise architecture for u-IT application in the agriculture sectors, which is called the u-Farm enterprise architecture with taking heterogeneous characteristics of agricultural products into account for. In addition, we also developed the RFID/USN middleware platform as a core infrastructure technology. Fo evaluation of the performance of the proposed u-Farm architecture and the RFID/USN middleware platform, the field-trial evaluation at the apple Agricultural Processing Center (APC) has been executed and the results shows that the proposed architecture and platform perform well in terms of information integration over the whole SCM process from the farming stage to delivering statge to the customers. It is expected that the proposed u-Farm enterprise architecture can be utilized as a standard information architecture, and the RFID/USN middleware platform can be a infrastructure platform for future u-IT based information technology applications and services in the agricultural environment.
