안전측면에서 볼 때 각종 유해위험물질 정보분석은 산업현장의 교육자료 및 기초자료로 활용할 수 있고 이러한 사전 교육을 통해 예비지식을 습득함으로써 유해위험물질로 인해 발생 가능한 사고를 미연에 방지할 수 있어 유용하다. 이로 인해 각종 유해위험물질 정보를 제공하고자 1994년 말에 한국산업안전공단에서 제시한 "화학물질의 위험특성 조사 및 MSDS의 제도화 연구 보고서"에서 물질안전보건자료(MSDS)를 검색하는 도스용 프로그램이 개발되었고 국내에서는 통신을 이용한 서비스로는 KISCO-NET의 물질안전보건자료를 검색하는 대화형 방식의 서비스가 있다. 최근 들어 국외에서는 하이퍼텍스트 포맷을 사용한 그래픽환경의 클라이언트 프로그램인 웹 브라우저(Web Browser)로 World Wide Web 서버에 구축되어진 물질안전보건자료를 검색하는 사이트(site)가 늘어나고 있다. 이는 웹 서버가 단순히 문서만 전송하는 것이 아닌 멀티미디어 서비스를 지원하고 있을 뿐만 아니라 그래픽 환경의 클라이언트 프로그램으로 자료의 검색이 손쉽다는 점에서 웹상의 데이터 베이스화는 늘어가고 있는 추세이다. 하지만 현재까지 국내에는 물질안전보건자료를 웹상에서 검색할 수 있도록 한 웹 서버 구축사례는 없다. 따라서 1995년 초부터 작업을 시작하여 물질안전 보건자료를 검색하는 웹 서버를 국내에서 처음으로 구축하였으며 현재 거의 완성단계에 이르러 시범운전을 하고 있다.운전을 하고 있다.

In this paper, we suggest the algorithm that inserts or deletes documents into web sites without creating tag. This algorithm uses tag which links between documents to automatically inset or delete the web documents. This study extracts the texts in the ... tag of the document to put into the structure as a type of graph creating the link as a node m of sub-node. That is, in this case of configurating new link between web documents, this algorithm allows to insert or delete the node to or from the graph without creating the tag. In the case of deleting the document, it removes the broken link connecting the sub-nodes of deleted node newly to its parent node.

This paper describes construction of web services system for secure message transmission appling web services standards. This system composes single sign on module, SSL module and secure message module. We applied these modules to price comparison site. Single sign on module used SAML standards. This module was designed, in order to provide authentication and authorization. As SSL module processes message encryption among end to end, messages of this system are secure. Secure message module is designed according to WS-Security standards and processes authentication, XML signature and XML encryption.

In the fourth industrial-revolution era, the construction industry is transitioning from traditional methods to digital processes. This shift has been challenging owing to the industry's employment of diverse processes and extensive human resources, leading to a gradual adoption of digital technologies through trial and error. One critical area of focus is the safety management at construction sites, which is undergoing significant research and efforts towards digitization and automation. Despite these initiatives, recent statistics indicate a persistent occurrence of accidents and fatalities in construction sites. To address this issue, this study utilizes large-scale language-model artificial intelligence to analyze big data from a construction safety-management information network. The findings are integrated into on-site models, which incorporate real-time updates from detailed design models and are enriched with location information and spatial characteristics, for enhanced safety management. This research aims to develop a big-data-driven safety-management platform to bolster facility and worker safety by digitizing construction-site safety data. This platform can help prevent construction accidents and provide effective education for safety practices.

To achieve web application security goals effectively by providing web security features such as information leakage prevention, web application firewall system must be able to achieve the goal of enhancing web site security and providing secure services. Therefore, it is necessary to study the security evaluation of web application firewall system based on related standards. In this paper, we analyze the requirements of the base technology and security quality of web application firewall, and established the security evaluation criteria based on the international standards for software product evaluation. Through this study, it can be expected that the security quality level of the web application firewall system can be confirmed and the standard for enhancing the quality improvement can be secured. As a future research project, it is necessary to continuously upgrade evaluation standards according to international standards that are continuously changing.

Construction management has been a target of the result and the index which were decided by whether the resourecs(time, cost and progress...etc) were used. but this has been serious problems in time and cost because of the shortage of storage space, the incident, lowering of efficiency for works, working impossible of between work categories and the demage of finished products. Therefore I noticed that more correct and more objective establish of data collecting system was necessary. it was through the diversification of information for exchange and communication between the construction site and participants. DVR(Digital Video Recorder) and internet technology were suggested for a solution to this problem. the collected information by DVR was divided to 3 steps as how long it used and how much it processed for improving efficiency of using and storage of information. and then it was verified through applying to cases at construction site.

Manufacturing execution system is a factory information system that handles production-related quality data as well as executes production plans of process unit for all resources in the production process on site. As the 4th industrial revolution, which maximizes an automation and connectivity with artificial intelligence, has become a hot topic, manufacturers are showing interest in building a smart factories, but enormous construction costs and unstandardized production processes are obstacles to smart factory construction. Therefore, this paper designs and implements a manufacturing execution system for building a smart factory in a deterioration factory. we propose a Web-based manufacturing execution system aiming at a smart factory at the basic level for steel wire processing. The proposed system will smoothly support interworking with the existing ERP system using REST APIs, and will consider extensibility so that it can be used in various devices and browsers. We will show practicality by implementing the proposed WoT-based manufacturing execution system.

인터넷의 발달과 함께 많은 학교들이 홈페이지를 운영하게 되었다. 학교 홈페이지는 온라인 상에서 이루어지는 학생과 학생, 학생과 교사 등 상호작용의 장으로서 그 역할을 담당하고 있고, 그 수단으로서 보드를 통해 생성된 게시판을 많이 이용하고 있다. 기존에 학교에서 사용되고 있는 게시판들은 일반 홈페이지에서 사용되는 보드를 이용한 것이 대부분이어서 학교상황에 최적화된 것이라고 보기는 어렵다. 본 논문에서는 사용자의 사용도를 중심으로 적응형 웹사이트를 구축할 수 있도록 지원해주는 학교용 웹보드를 설계하고 구현하였다. 특히 사용도를 평가하기 위한 알고리즘을 제시하고, 일반 학교에서 사용되고 있는 게시판을 분석하여 학교현장에 필요한 웹보드를 설계 및 구현함으로 사용자들은 쉽고 친숙하게 사용하고, 이를 이용한 학교홈페이지는 활용면에 있어 성과가 있을 것이라 기대된다.

It can be replaced with a smart work service centering on tasks that do not require on-site work among container terminal tasks. Here, the cloud service is helpful for small and medium-sized stevedoring companies as it reduces the cost and time required for initial system construction, and allows you to pay usage fees as needed. This study introduces a case study on the development of web services that comply with industry standards so that advanced ICT can be used in connection with the terminal operation system.

The slope monitoring systems which have been operating at home and abroad were investigated and then the real-time monitoring management system for evacuating inhabitants based on Web-EOC(Emergency Operating Center) was constructed. We tried to analyze realistically and precisely the situation by changing from the existing field-centered management to sensor-centered management that measures coordinates and provides in real-time data of measuring/monitoring sensors installed at a field site and developing related viewer programs. In addition, the 3D based monitoring management system, which has alarm functions in case of emergency and provides information about the evacuation place, was constructed on the base that is able to expand to nationwide fields by using Vworld 3D map. Ten steep slope monitoring sites were registered on Web-EOC slope monitoring management system constructed in the research and then application instances were suggested.
