Information filtering for internet search, in which new information retrieval environment is given, is different from traditional methods such as bibliography information filtering, news-group and E-mail filtering. Therefore, we cannot expect high performance from the traditional information filtering models when they are applied to the new environment. To solve this problem, we inspect the characteristics of the new filtering environment, and propose a semantic-based filtering model which includes a new filtering method using WordNet. For extracting keywords from documents, this model uses the SDCC(Semantic Distance for Common Category) algorithm instead of the TF/IDF method usually used by traditional methods. The world sense ambiguation problem, which is one of causes dropping efficiency of internet search, is solved by this method. The semantic-based filtering model can filter web pages selectively with considering a user level and we show in this paper that it is more convenient for users to search information in internet by the proposed method than by traditional filtering methods.

Deniable authentication protocol allows a sender to deny his/her involvement after the protocol run and a receiver can identify the true source of a given message. Meanwhile, the receiver has no ability to convince any third party of the fact that the message was sent by the specific sender. However, most of the proposed protocols didn't achieve confidentiality of the transmitted message. But, in some special application scenarios such as e-mail system, electronic voting and Internet negotiations, not only the property of deniable authentication but also message confidentiality are needed. To settle this problem, in this paper, we present a non-interactive identity-based deniable authenticated encryption (IBDAE) scheme using pairings. We give the security model and formal proof of the presented IBDAE scheme in the random oracle model under bilinear Diffie-Hellman (BDH) assumption.

인터넷 조사는 전통적인 방법에 비해 자료수집이 신속하고, 조사비용이 저렴하며, 양질의 자료를 얻을 수 있으며 멀티미디어를 활용한 고도화된 설문을 설계할 수 있다. 그러나 조사대상자의 신원 파악이 어려우며 구체적인 고객만족도에 대한 분석이 어려운 상황이다. 따라서 인터넷을 이용한 설문조사뿐만 아니라 고객만족도 조사까지의 확장이 가능한 시스템을 개발하였다. 이 시스템은 조사계획 과정에서 미리 조사 대상자에 대한 기본 정보를 취합하여 E-mail을 통해 조사 대상자의 특성을 파악할 수 있다. 또한 시스템을 통한 계획의 입력과 진행의 현황을 확인할 수 있다.

현대 사회에 있어서 신속하고 정확한 정보는 곧 수익증대의 중요한 요소로 자리 잡고 있으며 사회발전이 가속화 될수록 더욱 다양한 정보가 산출되고 있다. 그로인하여 광범위하게 분산되어 있는 정보의 추출은 매우 중요한 부분으로 부각되고 있다. 하지만 기존의 자료 집계 방법은 분산되어 있는 자료를 수집하기 위한 시간이 많이 소요되고 수집된 자료의 확인과정 및 통합 과정 또한 많은 시간이 소요되어 현대의 수많은 정보를 효율적으로 수용하지 못하고 있다. 이에 본 논문에서는 광범위하게 분산되어 있는 자료들에 대하여 효율적인 정보 추출을 제공할 수 있는 자료 집계 및 분석 시스템의 설계 및 구현 방안에 대하여 연구하고자 한다.

유비쿼터스시대 컴퓨터 인터넷 이용자는 웹상에서 제공하는 특성들에 따라 상거래 사이트에 대한 만족정도가 달라진다. 본 논문에서는 인터넷 구매 사이트에서 S/W(소프트웨어)를 구매해 본 경험이 있는 20세 이상의 일반인을 대상으로 2009년 3월 1일부터 2009년 3월 30일 까지 한 달 동안 개별면접 및 인터넷 전자우편을 통한 설문조사를 실시하여, 인터넷 이용자 만족에 영향을 미치는 인터넷 쇼핑몰의 특성 요인을 파악하였다. 이러한 연구결과를 토대로 본 논문에서는 소비자가 전문쇼핑몰의 어떤 특성에 관심이 있는지와 기업의 어떤 노력이 필요한지를 살펴봄으로써 이용자만족에 효과를 높일 수 있는 방법을 모색하고 인터넷 쇼핑몰 소비 전략의 시사점을 제공한다.

Purpose: This study was aimed to evaluate the effect of an internet community on knowledge, self-efficacy, and self-care behavior in workers with hypertension. Method: The research design used was a nonequivalent control group pre-test and post-test design. Sixty hypertensive workers participated in this study(Exp.=29, Cont.=31). The data was collected from the 3rd of November 2003 to the 27th of February 2004 using an interview with questionnaires. Information related to hypertension was provided on the internet community weekly and an e-mail newsletter was sent in order to increase participation in the internet community. We used a tool developed by Park Young-Im(1994) that measured knowledge related to hypertension and self-efficacy. A tool developed by Jung Mi-Young(2001) was used for self-care behavior. The collected data was analyzed with an $x^2-test$ and t-test using the SPSS WIN 10.0 program. Result: The internet community helped workers with hypertension to increase their knowledge related to hypertension, as well as increasing their self-efficacy and self-care behavior. Conclusion: An internet community could be applied as hypertensive nursing intervention.

Currently, obtaining information about the housing studies through the internet web sites is one of the outstanding mediums. Those are of the housings, architecture, interior design, furniture products, hotels and its journals, etc., and out of all those informations are the highly expected value of use. But. it may causes the public users to experience a negative effect, because many of those informations provided on the internet web sites related to the housing studies/informations are not providing an equal quality of information. And measuring the quality is also not easy. This study focuses on the establishment of evaluation criterion for the housing information-related internet web sites. In such a vein, it proposes a clear model to evaluate the information qualities with the 43 questionnaires / examining items. To test the questionnaires/rating items, the analysis has been implemented which has shown the reciprocal effect between the 2 major factors. One major factor with 4 variables on the information searches are (1) the accuracy/reliability of contents and techniques, (2) the design of a picture and communication, (3) the readability and security, and (4) the security of private information, and the other factor with 3variables on the additional services are (1) the diversities of contents and ease of orderings, (2) the abilities of search and e-mail, and (3) the events and after services. This study/rating model will provide the users with a fundamental material in evaluating the quality of housing information on the internet web sites.

This paper discussed the factors that necessitated information networking, types of networks, benefits of information networking, library information networking and the University of Port 0Harcourt library network initiatives. Information networking is a process of communication, exchange of ideas, resource sharing and collaboration between individuals, organizations, institutions and libraries and it is facilitated by ICTs and the internet for improved accessibility. It has been brought about by information explosion, rapid advancement in information communication technologies, inadequate funding and increased demand for quality information. Networks can be classified into local, national, regional, and international networks and are formed to serve different categories of user communities. Benefits of information networking include resource sharing, on-line conferences and participation in programmes at distant centers, collaboration among scholars in different countries. Communication flow through the internet, social media, and electronic mail. Library information networking started with the interlibrary loan which has metamorphosed into library consortia in which groups of libraries partner to coordinate activities, share resources and combine expertise. The University of Port Harcourt Library network initiatives started with an e-granary (a CD ROM) and the establishment of a local area network. The library subscribes to more than 10 electronic databases. Information networking has greatly improved the sharing of resources in acquisition and dissemination of information resources since no single institution can acquire the overwhelming number of information resources in their various formats.
