EJB(Enterprise JavaBeans)는 서버 상의 Java 컴포넌트와 그 컴포넌트를 위한 동작 환경을 제공하는 전체 프레임웍(Framework)이다. EJB 에서 동작하는 컴포넌트를 엔터프라이즈 빈(Enterprise Bean)이라고 하고, 그 컴포넌트가 동작하기 위한 환경을 컨테이너(Container)라 한다 EJB 에서는 기존에 개발자가 직접 컴포넌트로 제공해 주어야 하는 트랜잭션, 영속성, 보안문제, 데이터베이스 연결 풀링, 쓰레딩 관리 같은 기능을 컨테이너에서 처리해 줌으로 일반 개발자는 복잡한 하부 로직에 신경쓰지 않으면서 더 쉽고 빠르게 동일한 기능을 구현할 수 있게 된다. 본 논문에서는 이러한 EJB 컨테이너를 설계함에 있어서 하나의 중요한 요소인 트랜잭션 관리에 관한 설계를 논한다.

본 논문에서는 2G/3G/4G의 이동통신 기술을 기업에 적용하는 Femtocell을 이용해서 기업 무선망을 구축하는 환경을 목표로 한다. 이때 인터넷서비스사업자 혹은 기업이 이동통신망 기반의 응용 서비스를 쉽게 만들 수 있는 '개방형 무선망 Application Programming Interface(API)'를 기업향 Peer-to-Peer 서비스에 적용하는 방안에 대하여 제안한다. 이를 통해서 언제 어디서든 어떠한 기기를 통해서도 일관된 기업 서비스를 보다 단순화된 네트워 환경에서 향상된 서비스 품질과 함께 제공할 수 있다. 제안한 방안은 성능 개선을 평가하기 위하여, 대표적인 분산형 P2P 서비스인 Skype와 정성적인 성능 비교를 수행하였으며, 이를 통해서 보다 적은 개수의 서버와 절차를 지원하면서도 보다 향상된 서비스 품질을 제공하는 것을 확인 하였다.

Since the advent of conceptual prototype and seminal application, the notion of national systems of innovation(NSI) has drawn an increasing recognition. Although the morphological entanglement is still ubiquitous and the theoretical underpinning is fragile, NSI seems to be the last step toward an increasingly complex and encompassing concept of innovation research. Inevitably, NSI necessitates the comparative analysis in that it normatively attempts to draw best practices. Unfortunately, national profiles are too complex and diverse to derive a unified, concrete representation of the system, posing the problem of defining and modelling NSI for international comparison. This paper aims at providing an inductive taxonomy of NSI based on R&D structure of OECD member economies. Based on the similarity among national profiles, clustering method was applied to identify seven clusters such as (1) enterprise-government funding and enterprise-education performing group, (2) enterprise-government funding and balanced performing group, (3) balanced funding and enterprise-education performing group, (4) balanced funding and performing group, (5) enterprise-dominating group, (6) government-education dominating group and (7) government-education funding and education performing group. This paper by nature is descriptive and exploratory. R&D structure represents a static snapshot of innovative performance since it accounts for only the input side of NSI and thus may not offer convincing explanations of the holistic innovation system. A more detailed and extensive analysis on the economic/technological performance across clusters will shed light on the promising avenue to future research.

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.

At present, tendency of ERP(Enterprise Resource Planning) enterprises is that many ERP enterprises from abroad are rushing into capture of small and medium enterprises at home actively. SAP Korea and Korean Oracle have already showed their new product targeting domestic market of small or medium standing enterprise, and more, even MS(Micro Soft) also rushes into this market in earnest. The domestic business circle of ERP should prepare countermeasure by raising the perfection of product and having good command of minute marketing strategy to survive from aggressive strategy of SMB market. In addition, about the computerization of main affairs of business, ordering developing process was general that developing staffs analysed the affairs of each department that needed computerization and construct according to the operation process by using different tools, but condition is changing that businesses themselves are purchasing business application package from expert soft program enterprise and construct. Therefore, in this study, I try to grasp the problem of management, and define a new process that can help for more efficient management by making it an object producing and management module of enterprise 'K' that is one of domestic small and medium enterprise and that is operating ERP at present. As well, through the analysis of affair related producing, we are aiming to prepare for establishment of target, its range, and making the standard of result evaluation.

We introduce about XBRL, eXtensible Business Reporting Language, which is widely accepted as the international standard language for business financial reporting. XBRL is a language for the electronic communication of business and financial data which is revolutionizing business reporting around the world. It provides major benefits in the preparation, analysis and communication of business information. It offers cost savings, greater efficiency and improved accuracy and reliability to all those involved in supplying or using financial data. XBRL is a kind of XML application based on the open Internet technologies. We propose a framework for enterprise information supply chain using XBRL Web services. A Web service is defined as a software system based on XML and designed to support interoperable machine-to-machine interaction over a network by the W3C. Web services are frequently just application programming interfaces (API) that can be accessed over a network, such as the internet and executed on a remote system hosting the requested services. An XBRL Web service-based enterprise information supply chain enables for companies to implement seamless information supply chains from businesses to financial institutions, to supervisory authorities, and to other stake holders for real time information access. And thereby it is expected to contribute to the increase in the value of companies due to the enhanced visibility and transparency of accounting and management.

컴포넌트 기반 애플리케이션의 개발 및 배치를 위한 명세를 제공하는 EJB(Enterprise JavaBeans)는 엔터프라이즈 환경에서 가장 복잡한 트랜잭션 관리, 퍼시스턴스, 동시성 제어 등을 자동적으로 관리해주는 J2EE 환경의 핵심으로서 분산개발을 가능하게 한다. 본 논문에서는 EJB 기반 레거시 시스템에서 DAO의 트랜잭션 로직 복잡성과 시스템의 성능저하 문제를 해결하고자 한다. 따라서, 본 논문에서는 Iterator 패턴을 적용한 IDAO를 설계 및 구현하였다. IDAO는 컨테이너 관리 트랜잭션을 통해 데이터베이스 커넥션에 따른 트랜잭션 로직의 복잡성과 시스템의 과부하 감소 및 시스템의 성능저하를 감소시키는 효과를 얻었다.

ERP(Enterprise Resource Planning)는 제조 자원의 효율적 관리를 목적으로 하는 MRP(Material Requirement Planning)로부터 발전한 전사적 자원관리 시스템이라 할 수 있다. ERP 솔루션 분야는 최근까지 국내 솔루션 업체들이 주도해 왔으나 외산 솔루션 업체들이 본격 진출하면서 기업용 애플리케이션 업계의 격전지가 되었다. 이로 인해 국내 업체의 지속적인 품질 향상 노력이 요구되고 있다. 본 연구에서는 ERP 시스템 중, 건설 분야 ERP 시스템에 초점을 맞추어 품질향상을 위한 품질측정 방법으로서 품질특성 체계와 품질측정을 위한 척도를 개발하고 적용사례를 통해 효과적인 평가 방법을 제시하였다. 본 연구 결과를 건설 분야 EPR 시스템의 품질측정에 적용함으로써 품질향상에 기여할 수 있기를 기대한다.

[ $\circ$ ] Enterprise architecture is essential for ROI of e-Enterprise. $\circ$ An architecture is described from business, application, data and technical views and these must be complete and consistent. $\circ$ UML-based CBD is currently the best approach to obtaining architecture-centric, flexible and interoperable systems. $\circt$ Reuse of architecture, components, shared services and app frameworks is key to achieving both quality and productivity. $\circ$ Web service, the NBT, cannot be tapped without the architecting capability. $\circ$ Architects with world-class domain as well as software engineering knowledge are key to success of Korean software industry.
