데이터베이스와 연동하는 웹 응용에 대한 수요가 비즈니스론 포함하는 모든 분야에서 급속히 증가하고 있다. 그러나 급증하는 수요에 비해 웹 응용의 작성 및 유지 보수에 많은 시간과 노력이 소요되고 있다. 본 논문에서 소개하는 웹 스크립트 자동 생성기인 WebGen은 웹 응용에 필요한 폼들과 이 폼들을 통해 이루어지는 질의에 대해 데이터베이스와 연동하여 처리하는 웹 스크립트들을 자동 생성하는 소프트웨어 도구다. WebGen은 웹 응용 개발자가 작성하는 구성파일(configuration file)에 정의된 선언적인 내용을, 생성될 스크립트의 기본 원형인 내장된 템플릿(template)에 반영하여 5개의 웹 스크립트들(Search, Select, Edit, Information, Action)을 생성한다. Action 스크립트를 제외한 나머지 스크립트들은 사용자 인터페이스로 각각 해당되는 웹 폼을 생성한다. 따라서 WebGen은 웹 응용 작성을 위한 시간과 노력을 크게 줄여 웹 응용의 생산성을 향상시킨다. 상용 웹 스크립트 생성기들과 달리, WebGen은 상호 독립적인 템플릿들을 기반으로 하기 때문에 버전 관리가 용이하고 한 폼에 표현 가능한 정보도 관심의 대상인 엔티티 외에 이 엔티티와 직 간접적으로 연관된 모든 엔티티들을 포함한다.

Increased competitive challenges are forcing companies to find better ways to bring their applications to market faster. Distributed development environments can help companies improve their time-to-market by enabling parallel activities. Although, such environments still have their limitations in real-time communication and real-time collaboration during the product development process. This paper describes a web-based collaborative framework which has been developed to support the decision making on a 3D design developing process. The paper describes 3D design file for the discussion that contains all relevant annotations on its surface and their visualization on the user interface for design changing. The framework includes a native CAD data converting module, 3D data based real-time communication module, revision control module for 3D data and some sub-modules such as data storage and data management. We also discuss some raised issues in the project and the steps underway to address them.

Manufacturing companies should perform process planning and its evaluation concurrently with new product developments so that they can be highly competitive in the modern market. Process planners should make decisions in the manner of concurrent and collaborative engineering in order to reduce the manufacturing preparation time and cost when developing new products. Automated generation of analysis models from the integrated database, which contains process and material information, reduces time to prepare analyses and makes the models reliable. In this research, we developed a web-based system for concurrent and collaborative system for production flow analysis, using web, database, and simulation technology. An integrated database is designed to automatically generate analysis models from process and material plans without reworking the data. This system enables process planners to evaluate their decision fast and share their opinions with others easily. With this system, it is possible to save time and cost for assembly process and material planning, and reliability of process plans can be improved

Integration of engineering information through the IT (Information Technology) is very important key during the collaboration design process. How can we realize the data efficiently in real-time at the early design stage? How can we manage to integrate the separate information made by each designer or department effectively in real time? IT global trend is the unique way of handling these complicated problems from the information inundation. This paper suggests the design process management system deduced from the analytical results considering BPM (Business Process Management) solution workflow. Workflow based design process management system can help user share and integrate the needed information at the right time through Internet. It is found that the proposed tool works well for a beam design case, and this framework can be thus further expanded for an engineering design environment smoothly.

UDDI (Universal Discovery Description and Integration) Registry is used for Web Services registration and search. UDDI offers the search result to the keyword-based query. UDDI supports WSDL registration but it does not supports WSDL search. So it is required that contents based search and ranking using name and description in UDDI registration information and WSDL. This paper proposes a retrieval engine considering contents of services registered in the UDDI and WSDL. It uses Vector Space Model for similarity comparison between contents of those. UDDI registry information hierarchy and WSDL hierarchy are considered during searching process. This engine suppports two discovery methods. One is Keyword-based search and the other is template-based search supporting ranking for user's query. Template-based search offers how service interfaces correspond to the query for WSDL documents. Proposed retrieval engine can offer search result more accurately than one which UDDI offers and it can retrieve WSDL which is registered in UDDI in detail.

설계, 시공, 감리, 조달, 유지관리 등의 건설 전 단계에서 사용되는 서류작업은 Digital기술의 발전으로 전산화되고 있다. 또한 각 단계에 활용되는 자료는 자료 표준에 따라 점차 통합되는 추세에 있다. 한편 정보인프라의 확산은 건설산업에서 인터넷의 이용을 요구하고 있다. 기존 자료의 운용 방식은 서버-side 방식에 의존함에 따라 다중 사용자 접속시 전체 시스템에 성능 저하를 초래하거나, 이를 해결하기 위하여 많은 비용을 요구하며, 이에 따라 건설원가의 상승에 따른 경쟁력 약화를 야기 시킨다. 본 논문에서는 이를 해결하기 위한 방법으로 현재 사용되고 있는 Web용 자료관리 방법을 조사, 비교 분석하였다. 결과로 적합한 자료관리방법으로는 향후 인터넷으로 표준으로 대두되고 있는 XML을 채택하였다. XML자료관리 방식은 Client-side 방식이므로 자료관리 효율을 향상시킬 수 있다. 이를 이용해 건설분야에서 요구되는 관리기법 중 VE에 적용하여 시스템을 구축하였다. 본 논문에서 제시한 XML을 이용한 VE시스템은 방대한 자료로 구성되어있는 VE자료를 효율적으로 관리할 수 있다. 그러므로 이를 이용한 신속한 의사결정은 건설시장에서의 경쟁력을 높일 수 있을 것이다. 그리고 본 연구에서는 VE자료 관리의 효율 향상을 위해 XML based DBMS의 도입을 제안하고, 현장에서의 정보 접근성을 높이기 위해 Mobile Computing 기법 도입을 제안한다

One of the roles of the Semantic Web services is to execute dynamic intra-organizational services including the integration and interoperation of business processes. Since different organizations design their processes differently, the retrieval of similar semantic business processes is necessary in order to support inter-organizational collaborations. Most approaches for finding services that have certain features and support certain business processes have relied on some type of logical reasoning and exact matching. This paper presents our approach of using imprecise matching fur expanding results from an exact matching engine to query the OWL MIT Process Handbook. In order to use the MIT Process Handbook for process retrieval experiments, we had to export it into an OWL-based format. We model the Process Handbook meta-model in OWL and export the processes in the Handbook as instances of the meta-model. Next, we need to find a sizable number of queries and their corresponding correct answers in the Process Handbook. We devise diverse similarity algorithms based on values of process attributes and structures of business processes. We perform retrieval experiments to compare the performance of the devised similarity algorithms.

The small and medium construction companies are facing potential EHS(Environment, Health & Safety) of major accidents to cause casualties or a financial loss and increasing social responsibility. So, they have to voluntarily accomplish the EHS management system rather than passively with regard to EHS regulation. In this study, the framework of integrated EHS management system is developed based on cloud computing, and construction companies are to materialize self-regulation EHS process of construction workplace and to standardize the total EHS business process using the developed system. The proposed system also provides risk analysis, education/control and continuous improvement for EHS tasks and users can easily access the system on the web at a low price through cloud computing service. Eventually, the integrated system contributes to the managerial improvement by minimizing economic and physical loss caused by construction accidents.

This paper proposes an improved architecture of web-based monitoring systems for monitor of processes in plants from the soft real-time point of view. The suggested model is designed to be able to guarantee the temporal and spatial consistency and transmit the monitoring data periodically via the intranet and the Internet. The model generates one thread for monitoring management, one DB thread, one common memory, and corresponding monitoring threads to clients. The monitoring thread is executed during the smaller time than the execution time of the process used in the conventional methods such as CGI and servlet method. The Java API for the server API, VRML, EAI(External Authoring Interface) and Java Applets for efficient dimensional WEB monitoring are used. The proposed model is implemented and tested for a FMS plant, Some examples show that the proposed model is useful one.
