Geospatial information data came recently in use to build the location-based service in various fields. These data were shown via a 2-D map in the past but now can be viewed as a 3-D map due to the dramatic evolution of IT technology, thus improving efficiency and raising practicality to a greater extent by providing a more realistic visualization of the field. In addition, many previous GIS applications have been provided under desktop environment, limiting access from remote sites and reducing its approachability for less experienced users. The latest trend offers service with web-based environment, providing efficient sharing of data to all users, both unknown and specific internal users. Therefore, real-time information sensors that have been installed on steep slopes are to be integrated with 3-D geospatial information in this study. It is also to be developed with web-based environment to improve usage and access. There are three steps taken to establish this system: firstly, a 3-D GIS database and 3-D terrain with higher resolution aerial photos and DEM (Digital Elevation Model) have been built; secondly, a system architecture was proposed to integrate real-time sensor information data with 3D Web-based GIS; thirdly, the system has been constructed for Gangwon Province as a test bed to verify the applicability.

This paper outlines the concept of real time reference service(RTRS). Then, it analyzes real time reference service in the 13 libraries for effective reference service. As a result, the most used software was AOL instant Messenger, followed by Conference Room from WebMaster, and LivePerson. Hours of service was generally same as reference desk hours. The users were Students. faculty, staff, and alumni, This study also demonstrated how the RTRS in LC works. The results showed that real time reference was able to response to patrons quickly for reference questions with interactive method.

인터넷 사용의 대중화에는 웹 서비스의 힘이 컸다고 할 수 있다 지금까지도 웹 기반의 서비스가 점차 확대되고 있고 이에 따라 웹 공격과 웹 보안이 이슈가 되고 있다. 웹 서비스를 이용하는 어플리케이션은 기존 보안도구를 통한 분석 작업과 모니터링에 관리자의 개입이 많이 요구되었고, 자동화된 방법 중의 하나인 로그를 이용한 분석 방법들은 실시간으로 확인하고 대응 할 수 없는 단점이 있다. 본 논문에서는 기존의 웹 공격 탐지 방법과 시각화 방법들의 개선사항들을 제안한다.

The use of POP(Point of Production) systems which help to report the realtime production information to the supervisor class and to send commands to the shop floor is increasing gradually. Future companies will need to break the limit of regions and to exchange information among remote-sited departments and companies located abroad. In order to achieve this goal, Internet which is growing remarkably nowadays will be the best tool. In this research, a prototype of the POP system based on Internet is developed using the Java language. The developed POP system can monitor production status by collecting information from shop floor through a web server and can control production equipments from remote sites.

Recently, there has been much interest in the middleware that can smoothly acquire and analyze Geosensor information which includes sensor readings, location, and its surrounding spatial information. In relation to development of the middleware, researchers have proposed various algorithms for energy-efficient information filtering in Geosensor networks and have proposed Geosensor web technologies which can efficiently mash up sensor readings with spatial information on the web, also. The filtering algorithms and Geosensor Web technologies have contributions on energy-efficiency and OpenAPI, however the algorithms and technologies could not support easy and rapid development of u-GIS applications that need various Geosensor networks. Therefore, we propose a new Geosensor network middleware that can dramatically reduce the time and cost required for development of u-GIS applications that integrate heterogeneous Geosensor networks. The proposed middleware has several merits of being capable of acquiring heterogeneous Geosensor information using the standard SWE and an extended SQL, optimally performing various attribute and spatial operators, and easily integrating various Geosensor networks. Finally, we clarify our middleware's distinguished features by developing a prototype that can monitor environmental information in realtime using spatial information and various sensor readings of temperature, humidity, illumination, imagery, and location.

It is necessary to Self Directed Astronomy Learning based on web to bring up individuality and creativity. Accordingly, the contents of this study is constructed by Astronomy which connects with our life but unable to observe actually. The contents is dynamic animation for learner's interest. The learners are able to decide their grade for themselves through the on-line evaluation according to their precedence learning. The Learner is able to evaluate by multiple-choice provide feedback by realtime. The contents is learned by themselves and introduced by the familiar contents in the real life, that is presented as the subject of experiment or observation connected with learning contents in the life.

Recently, there are requires for auction system by growing up internet. This paper says if the customers add wonted goods to wanted list, the system automatically announce information to the customer via Inter Web browsing, whenever the proper goods to register to the auction system by seller. The system provides registration customer information, registration goods, wanted goods. And the application program can be downloaded from the Web System. Especially, this paper provides us very convenience check up service using the mobile phone, we can check our wanted goods or auction lists without regarding to place or time, we can alse purchase the goods more rapidly and easily.

In this paper, we propose the realtime network traffic monitoring system usin SNMP that can supported network and system operation, management, expansion, and design using network analysis and diagnosis to a network administrator. The proposed system consists of two parts: analysis server for collection and analysis of the network information, and supports real-time monitoring of network traffic, and client system shows user a graphical data that analyzed a returned result from the server. This system implements web-based technology using Java and contributes to enhance the effectiveness of network administrator's management.

현재의 만성질환 환자들은 잦은 검진과 치료를 요구로 한다. 하루에도 수차례 해야 하는 검사를 일일이 병원을 찾아가 할 수 없으므로 환자 개인이 측정기를 이용해 측정을 하고 있으나 그 때의 상황만 알 수 있을 뿐, 상태가 호전되고 있는지 또는 악화되고 있는지 포괄적으로 알 수 없는 것이 사실이다. 이에 본 논문에서는 개인이 가지고 있는 측정기에서 측정된 데이터를 인터넷 또는 통신모듈이 탑재된 측정기를 통해 실시간으로 전송받아 웹서비스를 통해 산재해 있는 분석엔진 시스템으로 전달하여 환자의 상태를 분석하고 의사와 환자에게 자동으로 알려줌으로써 환자에게는 자신의 현재 상태를 정확히 알고 치료에 임할 수 있게 하는 기회를 만들어 주고 의사에게는 상세한 추가정보를 비롯해 환자가 현재 제대로 치료에 임하고 있는지 확인 할 수 있는 정보를 제공하여 의사가 치료와 관련된 여러 판단을 쉽게 내릴 수 있는 만성질환자 상태 분석 및 제공 시스템을 제안하고자 한다.
