Nowadays many tasks are performed using the Web. Accordingly, many web-based application systems with various and complicated functions are being requested. In order to develop such web-based application systems efficiently, object-oriented analysis and design methodology is used, and Java EE(Java Platform, Enterprise Edition) technologies are used for its implementation. The security issues have become increasingly important. For such reasons, Java EE provides mechanism related to security but it does not provide interconnections with object-oriented analysis and design methodology for developing web application system. Consequently, since the security method by Java EE mechanism is implemented at the last step only, it is difficult to apply constant security during the whole process of system development from the requirement analysis to implementation. Therefore, this paper suggests an object-oriented analysis and design methodology emphasized in the security for secure web application systems from the requirement analysis to implementation. The object-oriented analysis and design methodology adopts UMLsec, the modeling language with an emphasis on security for the requirement analysis and system analysis & design with regard to security. And for its implementation, RBAC (Role Based Access Control) of servlet from Java EE technologies is used. Also, the object-oriented analysis and design methodology for the secure web application is applied to online banking system in order to prove its effectiveness.

우리나라에는 영어 학습을 위한 수많은 도구들이 있다. 특히, 최근 스마트폰의 출현으로 영어 학습을 위한 어플리케이션 개발이 활발하다. 그러나 대부분 영어단어를 단순히 암기하는 방법에 관한 것으로 텍스트 분석에 대한 어플리케이션은 부재하다. 본 논문에서는 사용자가 텍스트를 입력하면 단어가 갖고 있는 희소성에 따라 온톨로지 기반으로 분석되어져서 등급을 매기는 어플리케이션 시스템을 제안한다. 결과물은 파일 시스템과 데이터베이스에 저장되어 사용자는 텍스트의 희소성에 따라 선택한 텍스트를 읽음으로서 사용자의 눈높이에 맞게 신속하고 효율적인 어휘획득 능력을 갖게 된다.

Now we are following component-based software development as a solution to improve the reusability, reliability, and extensibility of the software. To support these, the developed components must be reused through component repository at software development. However, traditional centralized repositories couldn't activate component markets since not only the number of users were restricted but also most of the provided components were those on clients like user interface and so on. Recently, a lot of server-side components, reused in a specific domain, have appeared thanks to the development of both Internet technology and component technology such as EJB, DCOM, etc. Therefore, component repositories, based on domain information, classify and provide components and must offer web-based service for many users to use it stably. This study introduces the implementation of a component repository based on J2EE application model. It provides application developers with the service to search and extract appropriate components, and supplies them reliable services in web environment.
