인터넷의 발달과 함께 웹 기반의 멀티미디어 컨텐츠들도 많은 발전을 하게 되었다. 기존의 텍스트 형식만을 지원하던 많은 시스템들이 멀티미디어 기능을 추가하게 됨으로 보고, 듣고, 말하는 복합기능이 요구되었다. 또한 컴퓨터와 전화를 연결하여 데이터베이스 응용의 부가가치를 향상시키는 CTI 기술의 마른 성장은 다양한 분야로 확산되어 가고 있다. 본 논문에서 이러한 기술의 통합을 시도하여, Oracle8i DB를 공유한 Linux기반의 CTI프로그램과 Window기반의 ActiveX 모듈을 연동한 전화 음성게시판(Voice-BBS)을 설계 및 구현하였다. 제안한 시스템은 PSTN 상에서 뿐만이 아니라 웹상에서도 음성 데이터를 저장하고 재생할 수 있도록 설계되었다.

Most educational Web contents developed so far can be regarded' as another type of printed textbooks since they are made up of static lists of textual information. It results in a lack of capability in such educational viewpoints as interaction between students and/or teachers, self-directed learning of individual students, and so on. This paper proposes a new style of Web contents, which can improve the self-directed learning capabilities as well as the interaction between students, with the topic of "the life cycle of frog" that the student studies in the third year of elementary school. It has been designed to provide BBS and a studying material appropriate to the achievement level of individual students, and implemented with DHTML and Java.

It is difficult to find web contents for visual disabilities in spite of rapid growing internet users, infrastructures and advance of computer technology. For the case of usenet newsgroup concerning disabilities, hit rate is even less than E-mail because of lack of accessibility, educational support and economical expense for internet. This paper is addressed to voice usenet newsgroup service by using telephone or web browser for visual disabilities without additional S/W support such as 775, usenet program and installation program, suggests a design method and an implementation example for it. Main features of it are easiness of man machine interface, popularity of access device such as telephone or web browser and independency of particular news server by using NNTP. This system supports general MIME format, is implemented for usenet server of Korean Social Worker's Community and will be implemented for Gomduri InfoNet BBS of Korean Society for Rehabilitation of Persons with Disabilities.

본 연구는 웹의 비동기적 상호작용의 하나인 게시판의 교육적 효과에 대해 연구하는데 있다. 전자게시판의 활용은 주로 학생 상호간의 의사소통 수단으로 활용되어 왔다. 본 논문은 교사의 개입이 없는 방임형 게시판과 교사가 직접 개입하는 교사 개입형 게시판의 의사소통 능력과 상호작용의 질적 수준을 학습효과라는 관점에서 분석한다. 내용 분석을 위한 적절한 도구를 고안하고 교사 개입의 방법과 수준 등에 대한 논의를 한다.

Web Forensics algorithm used to an extraction of technical Web Forensics data to be adopted to proof data regarding a crime cyber a computer at data of a great number of log History is an essential element. Propose Web Forensics algorithm, and design at these papers, and try to implement in a Web server system of an actual company. And make the Web dispatch Loging system configuration experiment that applied integrity regarding Web log History information or authentication regarding an information source. Design Web Forensics algorithm and the Flow which used for Web log History analyses at server of e-mail, webmail, HTTP (Web BBS, Blog etc.), FTP, Telnet and messengers (MSN, NateOn, Yahoo, DaumTouch. BuddyBuddy, MsLee, AOL, SoftMe) of a company, and implement through coding. Therefore have a purpose of these paper to will contribute in scientific technical development regarding a crime cyber a computer through Web Forensics.

Background: Preclinical studies have demonstrated that ${\beta}$-adrenergic receptor antagonists could improve the prognosis of breast cancer. However, the conclusions of clinical and pharmacoepidemiological studies have been inconsistent. This review was conducted to re-assess the relationship between beta-adrenoceptor blockers and breast cancer prognosis. Materials and Methods: The literature was searched from PubMed, EMBASE and Web of Nature (Thompson Reuters) databases through using key terms, such as breast cancer and beta-adrenoceptor blockers. Results: Ten publications met the inclusion criteria. Six suggested that receiving beta-adrenoceptor blockers reduced the risk of breast cancer-specific mortality, and three of them had statistical significance (hazard ratio (HR)=0.42; 95% CI=0.18-0.97; p=0.042). Two studies reported that risk of recurrence and distant metastasis (DM) were both significantly reduced. One study demonstrated that the risk of relapse-free survival (RFS) was raised significantly with beta-blockers (BBS) (HR= 0.30; 95% CI=0.10-0.87; p=0.027). One reported longer disease-free interval (Log Rank (LR)=6.658; p=0.011) in BBS users, but there was no significant association between overall survival (OS) and BBS (HR= 0.35; 95% CI=0.12-1.0; p=0.05) in five studies. Conclusions: Through careful consideration, it is suggested that beta-adrenoceptor blockers use may be associated with improved prognosis in breast cancer patients. Nevertheless, larger size studies are needed to further explore the relationship between beta-blocker drug use and breast cancer prognosis.

Intranet is an internal information system which utilizes Intranet technology. Intranet is quickly adopted by many organizations worldwide. Electronic survey was conducted in Korea Electric Power Corporation where part of the information systems are offered by the Web-based systems. 842 questionnaires were analyzed to investigate the usage of the information systems and the Internet to access information. Some heavily-used and hard-to-access internal publications and outside publications were identified, and investigated whether they would be accessed via the information systems, the Internet, and the BBS. The study also Identified some problems associated with the information systems, md the users' preference of Web-based services was also examined. It was also examined whether the usage of the information systems, the Internet, and the BBS was different by some factors such as the kinds of work, the years at work, and the location of work. In conclusion, this study recommends that the Intranet should be established linking all the current systems of the company to provide wide variety of information the users want.

In this study we try to design and develop a mixed model of project-based learning with internet. In order to support the developed model, we separately developed a web-based tool, called Project Learning BBS. The classroom teaching for advertisement-photo production with the model has been carried out during May-July in 2002 and March-July in 2003 respectively with 40 students each. The overall activities of group collaborative work done during the teaching periods have been formatively evaluated with classroom observation, interviews and students' portfolios that were related to the processes of photo planning, video shooting and editing. It has also investigated how the students involved the web-based group discussion activities. In short, data analysis indicated that the participants accepted the proposed project-based learning model for their learning events in a positive way in order to increase the utilization of CMC.
