The use of the computer in medicine has been increasing rapidly. Despite this growing use of them, however, they have yet to assume a major role in assisting the physician. The purpose of this article, using dBASE ll, is to assist an anesthesiologist by rapid search of his(her) own references in preparing educational material or do research and so on. This software was written to be an efficient alternative to the conventional manual searching and to provide the following features: 1) personnel unfamiliar with computer technology could achieve satisfactory results. 2) rapid data entry of raw data with conventional keystrokes. 3) extensive data editing and manupulation capabilities. 4) entering each data typed by user was indexed alphabetically in sequence of authors' name. 5) easy search of data through the authors name, title, keyword and identifying of them in CRT displays or printer. Using a microcomputer for data processing had several advantages over a conventional manual method.: 1) less time required to retrieve information. 2) visual presentation of data was facilitated. 3) data were more readily obtainable. But the major disadvantage of a computerized system were the initial time consumed during the input of the data.

PURPOSE: We compared the calculated percent depth dose curves of 6 MeV electron beam to that of measured to evaluate the usefulness of Monte-Carlo simulation method in radiation physics. MATERIALS AND METHODS: The radiation dose values of 6 MeV electron beam using EGS4 code with one million histories in water were compared values that were measured form the depth dose curve of electron beam irradiated by medical accelerator ML6M. The central exis dose values were calculated according the changing field size, such as 5 X 5, 10 X 10, 15 X 15, 20 X 20 cm2. RESULTS: The value calculated showed a very similar shape to depth dose curve. The calculated and measured value of Dmax at 10 X 10cm2 cone is 15mm and 14mm respectively. The calculated value of the surface radiation dose rate is 65.52% and measured one is 76.94%. The surface radiation dose rate has vaied from 64.43% to 66.99. The calculated values of Dmax are in the range between 15mm and 18mm. The calculated value was fitted well with measured value around the Dmax area, excluding build up range and below the 90% depth dose area. CONCLUSION: This result suggested that the calculation of dose value can be replace the direct measurement of the dose for radiation therapy. Also, EGS4 may be a very convenient program to assess the effect of radiation dose using by personal computers.

Building a database file in the medical literature using personal computer enables individualized computer user to search with a small amount of time and effort. We developed a computer program for searching medical literature. This program was developed with Clipper database language, and runs on IBM-PC-compatible computers. The data is based on the Index of Korean Journal of Urology which was revised in 1991. The program is focused on the function of retrieving and printing of keywords, authors and titles, etc. We expect more advanced and beneficial program for searching of medical literature based on this program.

Serially sectioned images (MR, CT, and anatomical images) of the whole body are helpful in anatomy education because three dimensional images can be reconstructed with the serially sectioned images, and then the three dimensional images can be sectioned and rotated. To make the most important anatomical images of serially sectioned images, sectioned surfaces should be inputted into the personal computer after serial sectioning of the cadaver's whole body. In this study, equipments (digital camera and strobes) and techniques for inputting the sectioned surfaces into the personal computer to make anatomical images and for processing the anatomical images have been developed. By using these equipments and techniques, the anatomical images with the actual feature of the sectioned surfaces, the right alignment, and the constant brightness could be made. These anatomical images will be the basis for making good three dimensional images which are helpful in anatomy education.

PURPOSE: A film-based teaching file takes up space and the need to search through such a file places limitson the extent to which it is likely to be used. Furthermore it is not easy for doctors in a medium-sized hospitalto experience a variety of cases, and so for these reasons we created an easy-to-use digital imaging teaching filewith HTML(Hypertext Markup Language) and downloaded images via World Wide Web(WWW) services on the Internet. This was suitable for use by computer novices. MATERIALS AND METHODS: We used WWW Internet services as a resource for various images and three different IMB-PC compatible computers(386DX, 486DX-II, and Pentium) in downloading theimages and in developing a digitalized teaching file. These computers were connected with the Internet through ahigh speed dial-up modem(28.8Kbps) and to navigate the Internet. Twinsock and Netscape were used. HWP 3.0, Korean word processing software, was used to create HTML(Hypertext Markup Language) files and the downloaded images were linked to the HTML files. In this way, a digital imaging teaching file program was created. RESULTS: Access to aWeb service via the Internet required a high speed computer(at least 486DX II with 8MB RAM) for comfortabel use ;this also ensured that the quality of downloaded images was not degraded during downloading and that these were good enough to use as a teaching file. The time needed to retrieve the text and related images depends on the sizeof the file, the speed of the network, and the network traffic at the time of connection. For computer novices, adigital image teaching file using HTML is easy to use. CONCLUSION: Our method of creating a digital imaging teaching file by using Internet and HTML would be easy to create and radiologists with little computer experience who want to study various digital radiologic imaging cases would find it easy to use.

STATEMENT OF PROBLEM: The use of Ceromer is increasing in dentistry. But, the research of Ceromer has not been conducted much. Purpose: This study was to evaluate the marginal fidelity and internal adaptation according to marginal position. MATERIALS AND METHODS: In this study 60 resin crowns were fabricated. The measurements of the marginal fidelity were carried out using stereomicroscope SZ-40(R)(Olympus, Japan) and the measurements of fracture strength were done using Instron 8871(R)(Instron Co., U.S.A.) at a cross head speed of 1mm/min. All of the measurements were statistically analyzed by ANOVA test, multiple range test and Weibull analysis. Statistical significance was set in advance at the probability level of less than 0.05. All of the measurements were analyzed with Window SPSS(R) Version 10.0 soft ware for the personal computer. RESULTS: 1. There were no statistical differences of the marginal fidelity between Targis(R) and Tescera(R), but difference between these two and BelleGlass(R) according to materials. 2. There were no statistical differences of the marginal fidelity between no fiber group and fiber group. There were no interactions between each maerial and with/without fiber group in the marginal fidelity. 3. There were statistical differences of the fracture strength between Tescera. and BelleGlass(R), but no statistical differences of the fracture strength between Targis(R) and Tescera(R), Targis(R) and BelleGlass(R) according to materials. 4. There were statistical differences of the fracture strength between no fiber group and fiber group. There were no interactions between each material and with/without fiber group in the fracture strength. 5. When comparing the fracture surface, no fiber group showed the resin which were fractured at the labial surface and separated from the adhesion surface. In fiber group, the fractures took a place in resin compartments. CONCLUSION: The marginal fidelity and the fracture strength were clinically acceptable. From these results, Targis(R) and Tescera(R) were superior than BelleGlass(R) in the marginal fidelity. But, when applying these resin crowns in clinic, more careful consideration is needed and further study is recommended.
