For increasing needs about web-based XML applications, there has been a lot of studies about WIDL, CDF and OSD that are related to XML. Especially, the OSD format describes software packages and their inter-dependencies that is widely used in a CDF file, IT uses different forms for representing relationships among software pakages, because there has not been proposed a method of object modeling about it until now. In this paper, we propose a modeling method for the OSD and CDF documents using UML relationships. It is a part of the project to merge XML, applications and convert thd OCD and CDF documents into an IML class diagram to generate OODB sheme. We can esily not only visualuze implementation and dependency relationships among software packages but also understand and transform logical structure of XML documents using modeling functions.

Vulnerabilities in software can result in many social and economic problems once it has already been deployed and put to use. Thus, the vulnerabilities should be seriously taken into consideration from the beginning step of software development. A modeling and simulation method for software can be adopted as a testing tool for establishing vulnerability inspection strategies. For verification of usability of this strategy, in this paper, we modeled the behavior of a DNS system using Ptolemy and the simulation was performed. The result shows that a well-known vulnerability of DNS server could be effectively found, which confirms that the modeling and simulation can be used for vulnerability testing.

AMobile-supported spatial database systems have been introduced with development of mobile computing technology, they offer an advantage that we can access the data wherever we are. However, the studies on database system in traditional distributed environments must be reconsidered again, because of characteristics of mobile database system such as mobility and instability of wireless network. A new transaction model should be required for considering the characteristics, since especially a mobile computing environment is location-dependent, compared with the location transparency in a distributed computing environment. In other aspect, normally mobile host may be moving not in all space, but in some limited path. That is, a host is moving along the roads or the geographical features adjacent to the roads. The transaction processing should be considered not on the spatial coordinate but on the geographical features. In this paper, the feature based transaction processing model is proposed to process location-dependent transaction efficiently.

In this study, in Tongyeong area the distribution of marine products that were produced and treated through fishing and cultivating industry and the trend of main fisheries were investigated for fisheries distribution system and fisheries official circles, and then a structural model of fisheries distribution system for direct transaction was suggested under internet environment, which is an important scheme offering a necessary information rapidly and practically to both producers and consumers. Database system was structured according to distributed process. An op-elative scheme were suggested for sewers of local area information center, complementing functions to exceed each server's ability.

Lately computing environment is changing into integrating open system. This paper proposes Integrated Management Model to improve productivity about new software development. The model is divided by Management Model to deal with the rapidly changing environment effectively into three layers: the first layer classifies and displays information to users, the users, the second layer controls function, the integration and management layer, and the last layer manages data, the objects management storage layer. So it designs of Efficient Object Management Repository Using Integration Management Model. This might support afterward prototyping in maximizing the reuse of software, which is advantage to the integration of the system, and in promoting its productivity.

신발산업은 아직 표준화 되지 못한 부분이 많으며 현재 생산, 자재, 인사, 수/발주, 재고관리 등에 있어 각 회사마다 서로 다른 업무양식을 사용하고 있다. 그리고 동종 업계간에도 자료가 호환되지 못하고 있는 실정이다. 따라서 본 논문에서는 갑피생산을 위한 목록 표준화를 지원하는 시스템을 구현하였으며 특히 자재, 생산, 재고 관리를 웹 상에서도 유용하게 사용할 수 있는 생산관리 시스템을 구현하였다. 이 시스템은 ASP 기반의 신발 갑피 생산 웹솔루션으로서 거래처, 자재, 재고, 발주, 생산관리까지 일관된 관리체계를 지원해 통합정보인프라를 제공한다. 아울러 웹 기반으로 구축할 수 있도록 분산처리 구조를 가지며, 통합데이터베이스 기능을 사용하여 한번 입력된 데이터는 원하는 곳에서 반복 활용 가능 하도록 이루어져 있는 시스템으로 신발 갑피 생산 시스템에 효율성과 경쟁력을 극대화 시키는 시스템 이다.

The purpose of this study is to examine the The correlation between information processing types and mathematical communication abilities / word problem solving abilities. The results obtained are as follows: 1 Simultaneous/continuous information process types showed statistically high correlation with mathematical communication abilities. However, the correlation between simultaneous information process and mathematical communication abilities is a little higher than the correlation between continuous information process and mathematical communication abilities. 2. There is a high correlation between mathematical communication abilities and word problem solving abilities. Especially, speaking ability is much more correlated with four factors of word problem solving than reading, writing and listening, Through this study, we can conclude that information process types should be consider ed in order to improve mathematical communication abilities and mathematical communication abilities is essential in word problem solving.

이 연구는 한려해상국립공원 지역을 사례 지역으로 해상양식장 면적변화 등 변화탐지에 목적을 두고 1984년의 위성영상과 최근에 촬영된 LANDSAT 위성영상을 이용하여, 변화탐지기술과 영상처리기술을 활용 국립공원 경계내부의 양식장 현황파악과 변화과정을 모니터링하고 국립공원 관리에 활용할 수 있도록 시행되었다. 연구결과 1984년 3월 당시의 양식장 면적에 비해 2002년 4월의 양식장 면적이 63% 가량 감소한 것으로 나타나는데 이는 과거 통영만과 거제만 전처에 골고루 분포하고 있던 해상양식장이 2002년도에는 거제만 부근으로 집중하고 있는 것으로 분석되고 있다. 그 원인으로는 넙치와 우럭과 같은 고급어종을 기르는 해상가두리 양식장 형태의 자본ㆍ노동집약적인 양식으로 진행되어 가고 있는 추세를 반영하고 있다.

This paper describes how to implement reporting system for web-based information system. Reporting system is the S/W module that user is able to produce output of data in formal format. In Client/Server system, remote user can make formal output with client-side reporting component module. This client reporting component is usually system dependent. With web based information system, intranet, evolving, this client/server system need to he migrated to web-based reporting system. Reporting system component support multi-processing and real-time text/graphic output of server data. Ant Client can save or pint web page of client module. Especially, for real test its function and user interface, this reporting component is adopted in real network management system. The result shows that this reporting system component is very smart and excellent for real time web based monitoring system.
