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.

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.

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.

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.

Current diagnosis and surgical correction of craniofacial surgery would benefit from accurate and standardized data of computed tomography (CT). The ability of CT to identify bony and soft tissue features makes it particulrary useful for the management of craniofacial skeletal anomalies. Development of computer technology make it easy to store the large volume data of medical digital data and to manipulate the data at the office of surgeon. Digital data produced by modern modalities has its own advantages compare with conventional film datas; Accuracy, permanent storage, reproducibility. and etc. So the storage and archiving of the digital data of craniofacial field would have the utmost significance for the futher development of the craniofacial surgery. The raw data of thirty craniofacial CT data were transferred from a CT system to a personal computer via Ethernet TCP/IP connection. The transmission of DICOM data to the personal computer was successful and the transmitted images and their header information were displayed by DICOM viewing programs. This method of transfer and storage of digital data was useful for managing digital images and convenient for physicians in the hospital without PACS.

BACKGROUND: In hospital laboratory using Microscan, the search for an isolate or the analysis for antimicrobial susceptibility rates were obtained by the Data Management System (DMS) software. However, it is hard to convert DMS database to other file formats in addition to some limitation in using the database. We applied BacLink 2 and WHONET 5.1 softwares to convert and analyse DMS database for the utilization of the isolate profiles and the antimicrobial resistance rates. METHODS: Specimen and microbial data were printed as 'Short report form', an ASCII text file, from Microscan DMS. BacLink 2 software was used to convert the printed file to dBASE format file. Statistical analyses were performed using WHONET 5.1 software. RESULTS: Data of isolates were obtained as 'Short report form' in one month intervals. This file could be converted to other database file using BacLink 2 software. The antimicrobial resistant profiles were obtained, and the susceptibility, intermediate resistant, and resistant rates for each isolates could be analyzed. CONCLUSIONS: In this study, BacLink 2 and WHONET 5.1 software were successfully applied for the conversion of the database. Analysis of isolate profiles and antimicrobial resistant rates could be performed in other personal computer systems. The database management by BacLink 2 and WHONET 5.1 software could be applicable for the convenient statistical analysis in microbiology laboratories using Microscan.
