This paper introduces the design and implementation of a system which can get the NEMA2.0 image data from the hard disks of the imaging equipments directly,then analyzes and transforms these image data into the DICOM3.0 image data and sends them to the image server. The design has the advantages of reliable image quality, low cost and information.

OBJECTIVEAccording to the characteristics of digital medicine and the demands of digitalized management in hospitals, we established a storage system that is affordable, highly expandable, and reliable.

METHODSThe multi personal computer storage system (MPCSS) was constructed using hardware and software. The image data were archived from major servers to storage personal computers (PCs) by using Neusoft-picture archiving and communication system (PACS) and backed up on storage PCs. We simulated data loss on storage PCs and then restored the data. We also expanded the storage system to enlarge its capacity.

RESULTSThe average transfer rate from MPCSS was 27.7 MB/s, and the average cost for this system was yen 74/GB. In the testing stage, only 6 of 187 instances of data retrieval (from 100 patients) failed.

CONCLUSIONThe MPCSS is much less expensive than other high capacity systems or devices. It is feasible and suitable for digital image storage.

We have recentely built a cluster and backup system based on a SAN + NAS integrated storage system at a low price. The integration of SAN + NAS provides a storage system of fine quality, high reliability and high stability for hospitals. The article mainly introduces the choice of the project, the design of SAN + NAS integration and its implementation.

A method is well known to backup the necessary and useful data into CD-ROM. It is, however, difficult for multiple users to simultaneously access these CD-ROMs which are scattered. In this paper, we have developed the system of which many user can concurrently access some CD-ROMs which are scattered in several locations. The system developed in this paper can be operated under a client/sever network and in window 95 for an easily usage. The system has, now, evaluated very good in some library of university, official department, and hospital in korea. The developing of the system is, further, to extend CD-Recorder, Juke-Box, and so on.

The authors have made a CD-ROM titled 'Atlas of Pathology (AP)' for medical students to understand histopathologic findings with ease. We used a 35 mm film scanner to convert an existing file into digital images. A pathologist and two professional programmers collaborated to create the program 'AtlasMaster 1.0' based on (IBM) PC for organization of previously captured digital images. Minimum system requirement for the 'AP' was Pentium II 166 MHz, 32 MB RAM, Windows 95 or 98, 800 600 resolution, 16-bit color, 20 speed CD-ROM drive. The 'AP' was composed of a execution file (Pathology_Atlas.exe), a DB file (pathology.mdb), and reference files (*.bmp, *.jpg, *.txt). The DB file contained fields for chapter, section, disease entity, and information for location of reference files. About 1,000 color images for various kinds of gross and microscopic pictures were stored in the CD-ROM and those were classified according to the chapters, sections, and disease entities. The 'AP' was easy to manipulate, and had advantages of self-learning for students. It could be applied to other fields in which many images were dealt with, such as histology, radiology, endoscopy, dermatology, and plastic surgery. The 'AP' was handy and very useful for medical students to study pathology and it would be a powerful self-learning tool.

PURPOSE: This study analyzed the effects of a CD-ROM educational program for the prevention of sexual violence in relation to the sexual knowledge of middle school students. METHOD: A one group, pre-test-post-test design was used. The subjects of this study were 171 middle school students in Kangwon Province, Korea. The questionnaire included 34 items relating to overall sexual knowledge, and included questions on sexual violence. The collected data were analyzed using the mean, standard deviation and paired-t tests. RESULT: There were significant differences in the sexual knowledge by demographic characteristics between the pre- and post-tests. Of the 34 items, 20 showed significant differences in the sexual knowledge between the pre- and post-tests. CONCLUSION: The overall level of sexual knowledge of the students increased after taking the CD-ROM educational program. Further testing will be required to determine the effects of the CD-ROM using a control group and random sampling.

In the traditional cadaver dissection course, it is hard to demonstrate dissection skills to all the medical students because of limitations such as the high ratio of students to instructors and the lack of facilities. To overcome these limitations, we developed a digital anatomy dissection course. Through this system, it was possible to perform effective instruction of anatomic dissection. This method could provide the appropriate teaching in a short period of time. Furthermore, students can review the dissection course on digital files saved on a CD-ROM. Clinical cadaveric workshops can be provided by this method not only for students but also for continuing medical education for clinicians.

PURPOSE: This study was performed to develop the electronic textbook (CD-rom title) about preclinical practice of oral and maxillofacial radiology, using multimedia technology with interactive environment. MATERIALS AND METHODS: After comparing the three authoring methods of multimedia, i.e. programming language, multimedia authoring tool and web authoring tool, we determined the web authoring tool as an authoring method of our electronic textbook. Intel Pentium II 350 MHz IBM-compatible personal computer with 128 Megabyte RAM, Umax Powerlook flatbed scanner with transparency unit, Olympus Camedia 1400L digital camera, ESS 1686 sound card, Sony 8 mm Handycam, PC Vision 97 pro capture board, Namo web editor 3.0, Photoshop 3.0, ThumbNailer, RealPlayer 7 basic and RealProducer G2 were used for creating the text document, diagram, figure, x-ray image, video and sound files. We made use of javascripts for tree menu structure, moving text bar, link button and spread list menu and image map etc.. After creating all files and hyperlinking them, we burned out the CD-rom title with all of the above multimedia data, Netscape communicator and plug in program as a prototype. RESULTS AND CONCLUSIONS: We developed the dental radiology electronic textbook which has 9 chapters and consists of 155 text documents, 26 figures, 150 x-ray image files, 20 video files, 20 sound files and 50 questions with answers. We expect that this CD-rom title can be used at the intranet and internet environments and continuous updates will be performed easily.

PURPOSE: To develop a software program for computer-assisted instruction on MR imaging of congenital heart disease for medical students and residents to achieve repetitive and effective self-learning. MATERIALS AND METHODS: We used a film scanner(Scan Maker 35t) and IBM-PC(486 DX-2, 60 MHz) for acquisition and storage of image data. The accessories attached to the main processor were CD-ROM drive(Sony), sound card(Sound blaster-Pro), and speaker. We used software of Adobe Photoshop(v 3.0) and Paint Shop-Pro(v 3.0) for preprocessing image data, and Paint brush from Microsoft Windows 3.1 for labelling. The language used for programming was Visual basic(v 3.0)from Microsoft Corporation. RESULTS: We developed a software program for computer-assisted instruction on MR imaging of congenital heart disease as an effective educational tool.
