WWW(Word Wide Web)은 인터넷 상에서 광범위하게 분산된 다양한 형식의 데이터를 손쉽게 검색할 수 있도록 하며, 모든 응용의 사용자 환경을 손쉽게 포함시킴으로서 새로운 미디어 타입의 통합을 위한 가장 성공적인 기술로 평가받고 있다. E-Mail 서비스는 WWW 시스템의 가장 기본적인 기능으로, 인터넷 기술이 발전하고 사용자가 기하급수적으로 증가함에 따라 E-Mail 사용자도 늘고있다. 그러나 기존의 서비스는 HTML의 텍스트 기반 구조를 통한 비동기적인 형태의 서비스를 계속 유지하고 있어, 최근 인터넷상의 상당수를 차지하는 오디오, 비디오와 같은 실시간 환경의 멀티미디어 데이터들을 통합하는 좀더 동기적인 표현방법이 요구되고 있다. 본 논문에서는 E-Mail 서비스에 대한 동기적 방법론을 제안하고 구현하고자 한다.

This paper deals with Load Flow Program for client/server system. Clients play roles of input and output of the data. The client upload input-data file to the server which takes the part of the function of solving the Load Flow. The developed LF COM(Component Object Model) carry out solving the Load Flow and saving the result and the input data to DataBase. It proved the developed System to be compatible through the Case Study.

The objective of this research was to develop a framework of the Soil Environment Information Management System (SEIMS). In this study, we found that the SEIMS needs to be consisted of three sub-systems (i.e., information input system, DB system, and opening to the public system), which is operated on the Web-GIS basis. Also, we suggested structure and detailed items for each sub-system which are acceptable under the basis of current legal and institutional system. Furthermore, we made several suggestions for future-oriented system. Further researches need to be pursued for developing efficiently the SEIMS, such as 1) DB standards for the SEIMS, 2) guidelines for each cleanup phase, 3) improvement of the SEIMS for groundwater quality, and 4) integrated SEIMS for both soil and groundwater system.

Many researchers have proposed the various methods to detect illegal intrusion in order to improve internet environment. Among these researches, IDS(Intrusion Detection System) is classified the most common model to protect network security. In this paper, we propose new log format instead of Apache log format for SSL integrity verification. We translate file-DB log format into R-DB log format. Using these methods we can manage Web server's integrity, and log data is transmitted verification system to be able to perform both primary function of IDS and Web server's integrity management at the same time. The proposed system in this paper is also able to use for wire and wireless environment based on PDA.

XML is standard of web document, and is used in language for document data exchange. XML document is used as example that change existing document to XML or makes new document by XML increases and XML search system to search XML document efficiently accordingly is requiring. This paper describes design and implementation of query processing system for translating XML elements and data between XML documents and relational database and consist of XML to DB processor, DB to XML processor and XML document management processor. Through this, described for design and embodiment of efficient XML document search system of JAVA base using XQL that is proposed in language of quality of XML document.

대량의 정보를 빠르게 처리하기 위해 DBMS의 성능관리는 필수적이고 이를 뒷받침하기 위해 많은 툴들이 있다. 이들 제품 중의 하나인 국산 Maxgauge는 오라클 데이터베이스의 성능 현황이 어떤지 조회하고, 설정된 임계 값을 초과하는지 강시하고, 성능 문제 발생시에 원인을 추적하는 기능을 제공한다. 하지만 이는 설치의 번거로움과 국한된 환경에서만 서비스를 받을 수 있다는 한계가 있기 때문에 우리는 웹을 통해서도 시간과 장소에 구애받지 않고 성능을 관리할 수 있게끔 클라이언트/서버 버전을 웹 버전으로 설계 침 구현하였다. 1)서론 2) MAXGAUGE 소개 3) Web버전 설계 및 구현 4) 결론 및 향후구현방향 5) 참고문헌

Recently, cyberattacks are increasing in social engineering attacks using intelligent and continuous phishing sites and hacking techniques using malicious code. As personal security becomes important, there is a need for a method and a solution for determining whether a malicious URL exists using a web application. In this paper, we would like to find out each feature and limitation by comparing highly accurate techniques for detecting malicious URLs. Compared to classification algorithm models using features such as web flat panel DB and based URL detection sites, we propose an efficient URL anomaly detection technique.

This study mainly focused on the development of real-time based damage investigation system using web-GIS. The study area was Gangseo-Gu in Busan where frequently has relatively higher magnitude of damages from natural disasters. GIS DB was built to provide geospatial data such as 1:1,000 and 1:5,000 topographic maps and IKONOS high resolution satellite data. The web-GIS system has demonstrated the higher contribution for the better response and recovery against any type of natural disasters through real-time communication and data dissemination among government agencies and personnel. However, further researches need to be made to improve system capabilities. In addition, for more effective system operation and maximizing the benefits of exploiting web-GIS system, linkage with national DB such as NDMS is essential.
