관심사 분리는 소프트웨어 공학에서 핵심 문제로 다루어왔다. 기존의 OOD나 CBD등은 관심사를 분리하여 모듈화함으로써 프로그램 개발 및 유지보수를 용이하도록 발전해왔다. 하지만, 에러 처리나 로깅과 같이 여러 모듈에 산재되어 실행되는 횡단 관심사는 기존의 방법으로 해결하기 어려웠다. AOP는 이와 같은 횡단 관심사를 처리하려는 데 목적을 두고 제안된 방법으로 기존의 OOD나 CBD의 단점을 보완하면서 병행적으로 발전해왔다[1]. AOP가 나타난 가장 큰 특징은 기존의 개발 방법론을 기반으로 핵심 관심사를 개발하고 해결하기 어려운 횡단 관심사는 AOP로 개발하려는데 초기 목적을 두고 있다. 하지만, 대부분의 연구가 초기 요구사항 분석 단계에서 관심사를 명시하는데 초점을 두고 있을 뿐 구현 단계에서 효율적인 접근 방법은 아직 부족한 편이다. 본 논문에서는 Java와 AspectJ를 이용하여 구현한 간단한 사례 연구를 적용한 AOP 개발 프레임워크를 제안한다. AOP 개발 프레임워크에서는 관심사 분리, 구현, 평가의 세 단계를 기술한다. 이 중 구현단계에서는 핵심 관심사와 횡단 관심사 구현에 초점을 두고 AOP 기법에 쉽게 접근할 수 있는 방법을 기술하고 있다. 프레임워크는 프로그램 개발을 보다 용이하게 하고 확장 및 유지보수시 많은 시간을 단축시키려는데 있다.

Network technology has been developed for very high-speed networking and multimedia data whose characteristics are the continuous and bursty transmission as well as a large amount of data. With this trend users wish to view the information about the application services as well as network devices and system hardware. However, it is rarely available for the users the information of performance or faults of the application services. Most of information is limited to the information related network devices or system hardware. Furthermore, users expect the best services without knowing the service environments in the network and there is no good way of delivering the service related problems and fault information of application services in a high speed network yet. In this paper we present a web-based application management system that we have developed for the past year. It includes a method to build an agent system that uses an existing network management standards, SNMP MIB and SNMP protocols. The user interface of the system is also developed to support visualization effects with web-based Java interface which offers a convenient way not only to access management information but also to control networked applications.

Nowadays, the computational capability and graphical power based on PCs increase very rapidly every year. As a result, the complicated engineering or scientific problems that could have only been handled by supercomputers a couple of decades ago can now be routinely run on PCs. Besides, the PCs can be assembled in parallel to increase its computational capability theoretically without limitation. The Web-based interface and communication tools are also being enhanced very rapidly and the real-time distance learning (E-Learning) and project cooperation on web get increasing attention. Using the-state-of-the-art computational method, a number of complicated and computationally intensive problems are being solved by PCs. The results can be well demonstrated on screen by graphics and animation tools. Those examples include the simulations of fully nonlinear waves, their interactions with floating bodies, global-motion analysis of multi-unit floating production system including complicated mooring lines and risers. Several examples will be presented in this regard. Also, Web and java-applet based educational tools have been developed at Texas A&M University for better understanding of waves and wave-body interactions. The background and examples of such Web-based educational tools published in Kim et al. (2003) are briefly introduced here.

The objective of the present study lies in constructing web-based GIS system providing broad range of information applicable for power/telecommunications distribution facilities through cable. Nowadays, Korea is renowned forits faste sttele communications network across the nation enjoyable for being a test-runbed by worldwide contents providers. It is not too much to say that the trend is caused by the fact that Korea utilizes the cobweb-like power transmission cables applicable for the nationwide telecommunications networking. In particular, the trend has been all the more encouraged by the governmental drive to expedite the telecommunication network by way of the established power transmission facilities deemed as publicutility. Nevertheless, few can deny that the overexcessive competition among telecommunication service providers increasingly gives rise to unauthorized, arbitrary facilitation of distribution devices, which becomes much burden in operating the normal power/telecommunications distribution facilities by a power-generating company. In this regard, the study, to cope with such problems, attempts to develop a web GIS-based information management system compatible with NDIS(New Distribution Information System), a distribution facility management system now under operation by KEPCO, making advantage of GE Energy's SIAS(Smallworld Internet Application) technology. The model provided by this study is expected to get closer into effective operation of distribution facilities along with better sharing of information among conventional telecommunications operators, while getting rid of infringed facilitation cases
