  • The purpose of this research is to survey the current status of CD-ROM acquisitions and use at public libraries. For this purpose, the questionnaires prepared to examine the information environments, CD-ROM acquisitions and use as well as the future plans for CD-ROM use were sent to seven public libraries in Daegu. This paper consists of the introduction, the characteristics and trends of CD-ROM publications, the present status of CD-ROM publishing in Korea, and the analyses of acquisitions and use of CD-ROMs at public libraries. It is intended to find out if there is any relationship between CD-ROM publishing and CD-ROM use at public libraries. It concludes that the CD-ROM collections of public libraries are related to the publishing of CD-ROM, but the use of CD-ROMs cannot be claimed to reflect the publishing. Some interpretations and recommendations for the results are suggested.

  • This study intended to examine and analyze current status of CD-ROM use in reference and information service in major university libraries. 66 university libraries with holdings of over 200,000 were selected throughout the country, and questionnaires were sent out by mail for data collection. Current status of CD-ROM use, some issues and problems on CD-ROM searching by reference librarians and users, and future trends of CD-ROM use were examined. Few suggestions were made for the effective CD-ROM use in reference and information service.

  • The present study is aimed at the comparative evaluation of several CD-ROM MEDLINE versions for biomedical information retrieval and searching. The CD-ROM MEDLINE has recently been introduced in Korea and is actively using for health and medical professionals as an effective delivery tool of biomedical information. And this evaluative study revealed some different advantages and disadvantages in searching information among several CD-ROM MEDLINE versions. The present study also provides some findings of CD-ROM user's information seeking behaviors.

  • 최근 저장 장치로 많이 사용되고 있는 IBM PC의 CD-ROM(Compact Disc Read Only Memory)과 MP3(MPEG-1 Layer Ⅲ Audio) 디코더 칩을 이용하여 PC 작동과 관계없이 독립적으로 작동하는 CD-ROM 기반의 MP3 Player를 구현하였다. 여기서는 CD-ROM의 규격과 CD-ROM에 사용되는 ATAPI(AT Attachment Packet Interface) Format, MPEG-1 Layer Ⅲ의 오디오 부분에 대하여 알아보고 MP3 디코더 칩을 사용하여 CD-ROM에서 읽은 MP3 데이터즐 재생하는 방법을 취하였다. 이리하여 PC 자체로 MP3를 작동시키는 부하를 경감시키는 효과를 얻었다.

  • This study aims to provide a guide to the selection and purchase of a good CD-ROM encyclopedia by establishing evaluation criteria for CD-ROM encyclopedia. This study first divided evaluation criteria into the following rune categories: reviews available, print version, availability of trial disc, hardware requirements and ease of software installation, database contents, retrieval software, standalone/network version, standard/deluxe version, costs. Next, it suggested evaluation points and items in detail under each category.

  • This paper presents vibration control of a CD-ROM(compact disc-read only memory) drive feeding system consisting of a new type of CD-ROM mount using an electro-rheologocal(ER) fluid. Chemically treated starch particles and silicon oil are used for EF fluid, and its field-dependent yield stresses are experimentally distilled under both the shear and the flow modes. On the basis of the yield stress, an appropriate size of ER CD-ROM mount adapted to conventional feeding system is designed and manufactured. Vibration isolation performance of the proposed mount is evaluated in the frequency domain and compared with that of conventional rubber mount. The ER CD-ROM mount is then installed to the drive feeding system and the system equation of motion is derived. The skyhook controller is then incorporated with the fuzzy technique to improve the performance of ER CD-ROM mount. A set of fuzzy parameters and control rules are obtained from a relation between vertical displacement and pitching motion of the feedng system. Followingthe formulation of the fuzzy-skyhook controller, computer simulation is undertaken in order to evaluate vibration suppression of the CD-ROM drive feeding system subjected to various excitations.
