오늘날 현대사회는 인터넷의 보급으로 지식정보화사회로 급속도로 변화하고 있다. 이전 대량생산시대와는 달리 소비자들의 욕구와 기호는 매우 다양하게 형성되고 있다. 여러 기업들이 생산하는 제품들도 대부분 시기와 계절에 따라 생산율과 판매율이 달라지고 있는 실정이다. 제품들의 생산 및 원가산출, 적정재고량 파악을 위해 기업들은 BOM(Bill of Material)을 작성하여 관리하고 있다. 하지만, 다양하게 변화하는 현대사회에 요구사항을 반영하지 못하고 여러 문제점들을 야기하고 있다. 본 논문에서는 원자재 공급업체에서부터 판매회사까지의 자동발주시스템을 완성하여 보고자 한다.

The development of systems that can generate automatically instructional material is a challenging goal for the e-learning community. These systems pave the way towards large scale e-learning deployment as they produce instruction on-demand for users requesting to learn about any topic, anywhere and anytime. However, realizing such systems is possible with the availability of vast repositories of web information in different formats that can be searched, reused and integrated into information-rich environments for interactive learning. This paradigm of learning relieves instructors from the tedious authoring task, making them focusing more on the design and quality of instruction. This paper presents a mobile learning system (Mole) that supports the generation of instructional material in M-Learning (Mobile Learning) contexts, by reusing and integrating heterogeneous hypermedia web resources. Mole uses open hypermedia repositories to build a Learning Web and to generate learning objects including various hypermedia resources that are adapted to the user context. Learning is delivered through a nice graphical user interface allowing the user to navigate conveniently while building their own learning path. A test case scenario illustrating Mole is presented along with a system evaluation which shows that in 90% of the cases Mole was able to generate learning objects that are related to the user query.

In urban life, an interest in safety and demands for safety information about crimes and traffic are increasing. As well, communication on the internet is so active. In this study, we analyze web sites in US, UK, and JP, which have started safety map services, and then we provide basic material for the introduction of safety map into Korea. According to the analysis result, in US and UK, the safety map web sites are administered by the government and provided to the general public. The geographical area is provided around administrative districts and statistical data. In JP, The safety map web site provide not a one sided service but the service that user can directly take a part in, and also there is an web site for crimes against vulnerable people.

This paper describes a web-based system called DESIGNER for the analysis and design for automated material handling equipment(MHE) applications in manufacturing. DESIGNER models the processes for system integration, economic analysis, performance analysis, and automated storage/retrieval system(AS/RS) design. Based on the information specified by users, the various analysis modules are invoked to meet the needs of the material handling applications. The results of the analyses provide system users with useful data for material handling system design and decision on investment in automated MHE. Example problems are also presented to demonstrate the use of the system.

To survive in rapidly changing business environment, the enterprises of all over the world are trying to integrate their IT infra structure and are trying to automate their business process. Service Oriented Architecture (SOA) is being accepted as an IT standard to support efficient system integration and flexible business process automation between enterprises or departments. The material control system is required this software architecture between manufacturing company and materials supply vendors. This paper introduces concept of SOA, relevant technology about SOA such as Web Services and Business Process Execution Language (BPEL) and Enterprise Service Bus (ESB) and describes how to automate materials control process by designing the material control system based on SOA. The analysis of requirements is proceeded by Unified Modeling Language (UML) and SOA delivery strategy is selected the top-down strategy. And this paper describes how to derive services and operations and how to arrange services in three service layers and how to design business process.

Most power plants have operated many independent computerize systems for maintenance. Independence of systems have caused complexity of business process and inconvenience of computer system management. Because the equipment and material master data is not standardize and structurize, it is difficult to manage equipment maintenance history and material delivery. Especially equipment classification criterion is important for standardization of every maintenance information. It is necessary to integrate function of independent systems for business process simplification and rapid work flow. this paper provides equipment classification criterion design and system integration method with the case of live system development.

본 논문에서는 244개 국공립 초등학교 홈페이지를 직접 접속하여 불건전 정보 유통과 개인정보 노출 측면에서 학교 홈페이지의 안전 실태를 조사하였다. 홈페이지 게시판에 음란물과 상업성 광고들이 나타나는 학교가 62.7%에 달하였으며, 87.3%의 학교가 학생들의 사진, 주소, 전화번호와 같은 학생의 개인정보를 노출시키고 있었다. 분석 결과 불건전 정보의 유통은 대부분 자동등록 프로그램에 의한 것으로, 이는 무분별한 게시판 개설 및 부적절한 관리에 기인한다. 이와는 대조적으로 개인정보 노출은 교사와 학생들의 부주의한 정보관리에서 비롯되었다. 이것은 교사와 학생들이 개인정보 노출에 따른 위험성을 제대로 알지 못하고 있다는 것을 나타내는 것이다. 따라서 안전한 학교 홈페이지의 구축과 이용을 위해서는 먼저 실명에 의한 회원관리와 게시판 사용권한에 대한 통제가 강화되어야 한다. 그리고 현재 학교 홈페이지에 나타나는 역기능은 물론 잠재적 위험요인에 대한 교사의 올바른 인식이 필요하다.

PLM(Product Lifecycle Management) is an information management system that can integrate data, processes, business systems and human resources throughout the enterprise. BOM(Bills Of Material) is key data for designing, purchasing materials, manufacturing planning and management, which is basic for product development throughout the product life cycle. In this paper, we propose the efficient system to increase the data loading speed and the processing speed when using such large BOM data. We present the performance and usability of IMDG (In Memory Data Grid) for data processing when loading large amounts of data. In the UI, using the pure web grid of JavaScript instead of the existing data loading method can be improve performance of data managing.

This study was for applying web based street fashion design analysis system(web-SFAS), which was designed in preceding research and realized, to a practical use. Web-SFAS was developed to analyze data fast, accurately, conveniently, and to provide them to related fields by using Information Technology (IT) in fashion design industry. By inputting, sorting and analyzing actual image data into this system, it purposes to check if it needs to be corrected and to verify its operation and application. This study was collected in 2004 s/s 177 points image data and survey results input to the system This system analyzed the results as follow ; First, in all four areas of S/S, many people wear soft materials and plain T-shirts on top and tough material and plain jeans on the bottom. Second, In the case of dresses, in many areas people wear tough fabric plain A-line, one-piece dresses but in Hapsung-dong, many people wear geometrical figures. Third, fashion image, most people wear a sportive casual style with semi casual in a close second. Therefore, web-SFAS can be useful system analyzing for the trendy apparel type, design, material, color, image and variable in demography through street fashion image data.

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
