Medical education and research require various forms of information, which form multimedia data. While traditional computer can only deal with numeric and coded data, modern computer technology enabl es intergrated management of multimedia data. The present system was designed to perform convenient, acquisition, processing and analysis, and efficient presentation of medical multimedia data. APC-486 DX2 system epuipped with 8MB DRAM and 250 MB HDD provided fast enough computation speed, and image quality guaranteed by 17-inch SVGA color monitor. Both sound and image data are simultaneously acquired through a condenser microphone and audiocard, and respectively, in a video signal format. Printed pictures are digitized by a color scanner. Data transmission is also possible through a local area network (LAN). Acquired media data are structured in a hierarchy with the image data as apex. A variety of image processing and analysis algorithms were implemented and the media data can be reproduced simultaneously. Furthermore, simple and dynamic image animation can be performed to enhance data editing and authoring capability. Selected data sets can be reproduced in a user defined sequence, enabling "multimedia slide presentation". User interface was made in Windows format and all application programs were written in Borland C++ for future flexibility and extension. The present system will be of convenient use to acquire, manage, and present multimedia data for medical education and research.

OBJECTIVE: Thanks to the development of combining computer technology and communications, the concept of communications is undergoing radical changes. Using this method of communicating we have developed an Internet homepage of our department and another designated Medmark-neurosurgery. This homepage will be used to educate not only patients with neurosurgical disorders, but also residents in the neurosurgical field. It will be a forum for physicians to communicate among each other to discuss new skills, keep abreast of current develop-ments and share resources to enhance their practices. METHODS: The Internet homepage resources reside on an Alpha 1000 and local area networking system. Microsoft Windows NT and 95 were applied for both server and client use. Software for client use is also included. Uniform resource locator is SCHUH-neurosurgery is'http://hosp.sch.sch.ac.kr/ns' and for Medmark-neurosurgery it is'http://medmark.org/ns'. Material intended specifically for the neurosurgeon is classified and will be loaded on the server. RESULTS: The SCHUH-neurosurgery site had 3862 accesses for 2 years. The main page showed clinical, research and educational information. Personal homepage showed curriculum vitae, publications, research and clinical interest. It has been found to be very useful in communicating with neurosurgeons worldwide. The Medmark-neurosurgery homepage categorized 200 sites as 23 general information(23%), 9 consumer(4.5%), 8 association(4.0%), 56 departments(28%), 6 journals(3.0%), and 98 specialty(49%). Among the specialty sites were anatomy, tumor, vascular subcategories and much more information. CONCLUSIONS: We will present ideas on current and future applications of the Internet homepage in reference to neurosurgery with a comprehensive list of neurosurgical resources available on the Internet.

Electromagnetic interference (EMI) can affect various medical devices. Herein, we report the case of EMI from wireless local area network (WLAN) on an electrocardiogram (ECG) monitoring system. A patient who had a prior myocardial infarction participated in the cardiac rehabilitation program in the sports medicine center of our hospital under the wireless ECG monitoring system. After WLAN was installed, wireless ECG monitoring system failed to show a proper ECG signal. ECG signal was distorted when WLAN was turned on, but it was normalized after turning off the WLAN.

BACKGROUND: Reduction of the turnaround time of laboratory tests including blood collection and patient data input into computer is an essential step for improvement of laboratory services. We have evaluated some working situations for blood collection and patient data input into computer to find the best way to reduce the turnaround time in the first step of laboratory tests. METHODS: The time required for blood collection including waiting time and the time for patient data input into computer were recorded at five different situations consisting of various combinations of phlebotomists, a guide and a computer system with barcode labelling. The data were analyzed by Student's T-test and SAS (version 6.04, U.S.A.). RESULTS: A significant reduction of blood collection time was achieved by adding of one more phlebotomist rather than by adding of a guide, by adding the barcode system only, or by adding a clerk and the barcode system. The time for computer input of patient's information was remarkably reduced to one-fourth by the introduction of barcode system. CONCLUSIONS: The introduction of barcode system into blood collection process could not bring a reduction of turnaround time in blood collection however adding a phlebotomist brought a significant reduction of the time. The barcode system was only effective in a computer input of patient's information.

Nosocomial infection management is one of the most important subjects in terms of risk management in a hospital. To achieve the nosocomial infection management appropriately, both public relations and information gathering are important. When it comes to publicity, it is desirable that information is offered quickly and efficiently and the personnel are able to access the information easily anytime and wherever they are. As for information gathering, it is also important to collect the information concerning the nosocomial infection promptly, and to tell it quickly to infection management persons including infection control team members. The infection control committee of our hospital has engaged in both publicity and information gathering by using the committee web site established in the LAN of the hospital since January 2004. The web site carries notifications, organization chart, list of committee members, various manuals, guidance of educational activities, infection management, etc. It is also used for questions and answers, and gathering information concerning nosocomial infection. The number of times the web site was accessed was about 200 every month, and was considerable at night and on holidays. This method of using the web site seems to be useful to promote nosocomial infection management.

OBJECTIVES: The purpose of this study was to develop a prototype wireless local area network (LAN)-based tracking system and evaluate its efficacy. METHODS: A wireless LAN-based tracking system was developed with a personal digital assistant (PDA) having a simple text messaging function and a prototype stand-alone tracking device. Evaluation of the effectiveness of the tracking system was performed in two ways. Twenty-five messages were sent to nurses by direct communication and 46 messages were sent by the wireless system. Thirty cases by nurses and 30 cases by the wireless system to locate hospital equipment were performed. The time required to transfer messages and to locate equipment was measured and analyzed with a Mann-Whitney test and a paired t-test, respectively. RESULTS: The mean time required to transfer messages by direct communication and by the wireless system were 37.92 +/- 19.19 seconds and 30.65 +/- 9.80 seconds, respectively which were not statistically different (p = 0.108). The mean time required to locate equipment by the nurses and by the wireless system was 234.00 +/- 59.99 and 23.97 +/- 6.17 seconds, respectively which was statistically different (p < 0.001). CONCLUSIONS: The wireless LAN-based tracking system can save time for nurses to communicate and to check for the location of equipment in wards which allows nurses to spend more time and attention to patient care and safety.
