Many more use e-mail purely on a personal basis and the pool of e-mail users is growing daily. Also, the amount of mails, which are transmitted in electronic commerce, is getting more and more. Because of its convenience, a mass of spam mails is flooding everyday. And yet automated techniques for learning to filter e-mail have yet to significantly affect the e-mail market. This paper suggests Web Mail Filtering Agent for Personalized Classification, which automatically manages mails adjusting to the user. It is based on web mail, which can be logged in any time, any place and has no limitation in any system. In case new mails are received, it first makes some personal rules in use of the result of observation ; and based on the personal rules, it automatically classifies the mails into categories according to the contents of mails and saves the classified mails in the relevant folders or deletes the unnecessary mails and spam mails. And, we applied Bayesian Algorithm using Dynamic Threshold for our system's accuracy.

E-mail became the universal communication means today that is widely used socially. It is being used as an important communication means in a problem about interchange and commerce with foreign countries as well as exchange of opinions within public agency and in relationship with other institution, corporation or organization. Also, in the trend of pointing to digital government, e-mail is becoming the primary means of contacting with the people. However, our country is not recognizing e-mail as official record yet, and is not offering any guideline for managing e-mail. E-mail is one form in electronic record, and needs to be acquired and managed as record given having been used for public service. It is essential to prescribe meta-data elements necessary for acquisition and management. Accordingly, the final purpose of this study is to offer the foundation in the e-mail record management of our country, by suggesting meta-data elements that will need to be secured when acquiring e-mail record.

We propose an undeniable digital signature scheme which is practical since it has less computation and communication overhead than Chaum's one. We expect that this protocol be useful to develop secure systems such as electronic contract system, electronic mail system and electronic cash system.

The purposes of this study were to define the current status of information infrastructures and electronic information retrieval systems in university libraries in Korea, to assess the impact of information technology on library collection development in Korea universities, and to determine the relationship between electronic information retrieval service and library collection development. Data was collected by a mail survey. Questionnaires were mail in December, 1997 to all 134 4-year university libraries. Approximately 78 percent of the questionnaires was returned.

Lately, electronic commerce through the Internet has been rising in attention. An important element in such commerce is EDI. EDI is mainly used with VAN but its use is not common due to the high cost of EDI transfer. Thus, only large corporations with frequent use of EDI are able U benefit from it, To smaller companies that have small usage, EDI is becoming a burden. Considering this fact as well as current changes within the enterprise environment, it is apparent that a new generation of EDI is required. To resolve the problems of VAN EDI, the proposed Internal EDI was implemented. Internet EDI deals with the use of the widely spread Internet instead of VAN. By using Internet EDI, it is possible to reduce the high cost that came when using VAN. There would be no extra transfer cost since transmission will be done through the Internet. Also, electronic commerce that is mostly used today between an individual and a company may grow to become a true electronic commerce between companies.

Many users feel a great pain owing to losing edited files. It is very serious loss in time and money. This problem occurs because email attachments are edited in 'Inbox' and the compute immediately shuts down with 'Save'. This is caused by the illusion that the 'save' in a temporary folder is saved to a secure hard disk. Our thesis proposes a loss-prevention system WatchDog for safe storage and folder management of the e-mail attachments. The proposed system operates a warning window pop-up when we 'Open(O)' and 'Save' the attachment. In addition, convenient folder management plans for safe copying and movement are shown through example programs.

The purpose of this paper is to develop standardized metadata elements of e-mail records with respect to international standards based on analyzing the Australian Government Email Metadata Standard(AGEMS) elements and Korean Records Management Metadata Standard including e-mail records. To achieve the goal, we investigated and analyzed ISO15489 and ISO 23081 which are the international standard related to records and metadata of records. Second, a case study related to the features of e-mail records produced in public institutions in Korea was performed. Third, we made a comparative study of Australian Government Email Metadata Standard(AGEMS). With the results, we proposed mandatory and optional metadata elements for managing e-mail records. Also, the DTD of proposed metadata elements were developed. The proposed metadata elements of e-mail was applied to e-mails which were produced from a administrative information system of a local government in Korea.

The purpose of this research is to evaluate the degree of transactions of the electronic commerce in the hospitals. We created well-organized questionnaire to achieve this goal. we did telephone interviews with the hospitals, and then we reached out to the hospitals by e-mail and postal mail. We interviewed 311 hospitals, and 104 hospitals participated in this study. We conducted cross tabulations. The results are following : Among the subjects, male was 77.9%(81) and female was 22.1%(23). 51.0% of the hospitals used electronic commerce in their work purpose. The proportion of the hospitals that started their electronic commerce before 2000 years was 30.2% and after 2000 years was 69.8%. In the major electronic commerce service providers, 30.4% of the hospitals had their contract with auction, 18.4% of the hospitals had their contract with public procurement services. which is running by Korean government, and 11.8% were with EZmedicom and 10.8% were working with Carecamp. Through electronic commerce, the most high usage was office supplies 41.0% and the send area was medical supplies 11.2%. The results of this study suggest that electronic commerce in health care field is a very new area compared to other industries. There may be lots of barriers in the aspects of a way of working and norms of health care field. Electronic commerce system and contracts with their electronic commerce service providing partners.

This paper describes the design of Korean electronic Mail system which is installed at DECnet in Seoul National University computer center. In our system we introduce facilities for command processing and naming service in Korean, which was impossible in most mail systems. We emphasize flexibility in the design of Message Transfer Agent, for there are numer-ous code representions for Korean language.
