  • The traditional a roaches to software development, such as XP, UP, CBD and other CASE tools, are useful for constructing various software components. However, they are not designed to face the challenges of open environments that focus on service. The Service-Oriented Architecture(SOA) is a component architecture that interconnects an application's different functional units, called services. SOA provides a good way to integrate the business process through well-defined interfaces and contracts between business services. In this paper, we propose a method of business process modeling based on SOA with a P2P approach. Also, A P2P business process modeling system is presented. This, results in admitting the reality of enterprise that changes on the basis of services, and suggests more efficient and visual direction for the process integration between enterprises.

  • The NCO effectiveness analysis related elements and their relationship are more complicated than the PCW. However, Effectiveness analysis models provide single effectiveness element centric effective analysis method so far. Therefore, A model to provide unified view and common language about NCO effectiveness is required. EA use reference model as a common language to control complexity and change. The objective of this study is presenting a methodology to develop NCO effectiveness analysis model based on reference model and implementation model concept. To do this, First, the concept of EA based reference and implementation model is studied, Second, we study related effectiveness analysis method and model component and their relationship identification methodology, third, we propose methodology to develop NCO effectiveness analysis model. Finally, we prove the effectiveness of the methodology using case study.

  • The purpose of this paper is to imply for the assessing framework of next generation Enterprise Portals'(EPs) function through the lens of organizational knowledge creation. As the emerging "suite" products such as Smart Enterprise Suite (SES) converges EPs with collaboration and content management, EPs are no longer just a gateway to information and content. EPs are emerging as the center of convergence for many complementary technologies. Considering that this trend is common and knowledge creation is one of key goals of EPs, it is important to assess EPs' function through the knowledge creation process. This paper reviews literatures to set initial assessing elements of EPs' function, then adopts Delphi Technique to prove and categorize the elements according to the knowledge creation process. The samples are consisted of 7 professional knowledge management consultants at Entrue Consulting Partners, LG CNS. This paper may be significant in providing a new vision to the evaluation of EPs by combining a theoretical model with a practical situation.

  • The investment on informatization has caused the increase in complexity of IT resources as well as inefficiency of Information system management and redundant investment. Thus, the idea of EA (Enterprise Architecture) was developed in order to manage the IT resources efficiently but the systematical guideline was insufficiently provided in data area.. Because of this, it is necessary to make full use of DRM (Data Reference Model) so we can enhance the sharing and reuse of data between several institutions in public sector by extracting and managing data behind processes. In this study, we recognize the necessity of improvement on data classification which is highly utilized and present the direction for the data classification rethesis.

  • Many firms have had a passion for IT investment for years. Despite such a continuing investment in IT, the application of newer technologies to business work doesn't guarantee a great success. Some IT projects were doomed to failure or ineffectiveness. What could we do to lead IT project to the territory of effectiveness? One plausible and inevitable avenue is enterprise architecture (EA), which requires one to first come up with a simplified view of the complex entity to be designed and then proceed to design and develop it as directed by the architecture. Though there have been more materials on such EA work and real cases, there still exist a doubt about why EA is needed and how a firm can introduce it. This article first presents a structured understanding about EA and then describes the necessity, and the introducing ways of EA.

  • In a knowledge-information based society, effective management across IT industries, value of information and interoperation are more important than eyer before. Therefore, ITA/EA which helps to plan and manage IT systematically and effectively, was enacted and announced in 2005 and has been considered as an innovative IT management approach. Unfortunately, however, new standardization of ITA/EA has not fully discussed yet. How to successfully apply EA/ITA to IT is considered as the most urgent challenge and this study aims to find out the most effective method. To this end, it was emphasized that training systems for specialized experts must be operated systematically through 'standardization of terms and tasks' and 'standardization of manpower training' and certification of specialty must be newly established. In addition. it was strongly demanded that dual structure caused by mixed concepts between ITA and EA must be eliminated. At the same time. a new model for domestic standardization was suggested so that not only ITA/EA can be recognized as IT engineering but also professional engineers can accept ITA/EA as a scientific field. In summary, this study is intended to propose how to improve information management efficiency through ITA/EA.

  • According to the E-Government Readiness Index announced by UN in 2012, the Republic of Korea ranked top again following the last time. However, according to the national competitiveness index announced by IMD, that of the Republic of Korea has still ranked in the world's top 20 for three successive years. In particular, the area of government efficiency took the 25th place in 2012, descending three steps compared to that in 2011, and the area of infrastructure related to informatization has been ranking 20th for three years. This phenomenon can prove that the Republic of Korea's informatization is not producing good outcome, and the investment in informatization is not creating good effects. This phenomenon was analyzed in terms of a life cycle of informatization in this study. As the result, it was revealed that structural problems remain in each step, the linking of information in each step is insufficient, reasonable trace management is absent ,and information management depending on systematic plan is lacking. To solve these problems, improvement measures through architecture consideration were suggested.

  • The purpose of this research is to propose a practical guideline for activating EA which has been operated in the public institutions. For this purpose, how EA is being operated in the public sector, was analyzed from the viewpoint of IT Governance and on the basis of the result, key activities for EA managers could be developed. The key activities were also compared between the two different groups in terms of EA Maturity Level and the difference in the key activities between the two were examined. As a result, it was found that the use of EA has effect on building and improving IT management systems. It is suggested that the Relational Mechanism should be better understood and recognized as necessary activities for activating EA. In addition, the higher the level of EA maturity is, the more likely such various effects as the enhancement of IT management system, user satisfaction, IT utilization, and the improvement of business can be produced. This result could be interpreted that such desired outcomes of EA could be realized only when EA is actively utilized.

  • Nowadays the fair queuing field is studied actively for solving the unfair queuing problem which degrades the service performance of various applications on network. Above all DRR is a scheme that has lower work complexity and can be implemented easily. It guarantees the fair service by serving each queue every round Service Quantum(SQ) that includes the service deficit of the previous round. But it increases the delay by the numbers of unnecessary resetting of SQ or round circulation for the service that have the packet size over maximum several kbyte. In this paper, We propose the method that sets SQ dynamically to minimize this problem and the method that minimizes the work complexity on processing of packet. The proposed scheme minimizes the delay on various applications in enterprise environment by setting SQ dynamically and processing the packet simply.

  • Recently, enterprise storage systems that require large-capacity storage devices to accommodate big data have used large-capacity flash memory-based storage devices with high density compared to cost and size. This paper proposes a high-efficiency life prediction method with slope descent to maximize the life of flash memory media that directly affects the reliability and usability of large enterprise storage devices. To this end, this paper proposes the structure of a matrix for storing metadata for learning the frequency of defects and proposes a cost model using metadata. It also proposes a life expectancy prediction policy in exceptional situations when defects outside the learned range occur. Lastly, it was verified through simulation that a method proposed by this paper can maximize its life compared to a life prediction method based on the fixed number of times and the life prediction method based on the remaining ratio of spare blocks, which has been used to predict the life of flash memory.
