This Study aims at developing electronic application protocols to provide the requiring hospital with basic information necessary for the treatment of the emergency patients, and thereby contributing for the improvement of the quality care and the related medical systems. For the study, data on the basic items of information were surveyed from the five large-sized hospitals with 300 inpatient beds or more. The delivery system between hospitals, data structure and the electronic protocol to provide the basic information were designed and tested. The results and conclusions of the study are as follows: Firstly, besides such information items that have been usually used as allergy, drugs used and disease history, five items of patient personal information, three items of insurance related information, and eleven items of diagnostic and treatment information were additionally included as basic items of information of the hospital emergency patients. Secondly, the information delivery system was designed in the way that the emergency information center takes the intermediate role in the process of the information delivery from the needing hospital to providing one. Thirdly, data structure were defined and designed for each stage of information delivery, and HL7 protocols were designed using the data structure. Fourthly, the HL7 protocols were tested using XML, and it was verified that the delivery of the basic information functions as intended, and Finally, in order for the HL7 protocols to be put to practical use, an automated electrical transmission system that can provide to the hospital that needs the basic information should be designed and constructed in the corresponding area.

As internet becomes very important communication means for numerous people, a variety of advertisement are beginning to appear on the internet. People can get information about various things and do shopping via internet. This study was carried out to investigate the effect of internet advertisement on various groups. For this study, 200 people were surveyed. The results obtained were as follows: 1. Among the various advertisement types, since most people use e-mail and check e-mail very often, the advertisement through e-mail turned out the most effective advertisement means. 2. The type of advertisement using animation and moving pictures were preferred for most consumers. 3. As for the age groups, young people had the preference for the banner style and old age groups were interested in advertisements including free gift or discount events. 4. As for the favorite hours, the people in the twenties and the thirties preferred evening time(18:00 to 24:00) and people in the forties and fifties afternoon(12:00-18:00). 5. Male consumers showed preference (or the advertisement including free service programs and female consumers preferred the advertisement including discount programs or gifts.

PCS망에서의 위치관리 방법에 관한 연구

To support a lot of subscriber and multimedia services in the PCS network, wireless network is required to have higher bandwith utilization. And the challenge of supporting rapidly growing numbers of mobile susbscribers is being met through increasingly smaller radio cells. This, however, results in increased signalling for location management procedures, which reduces the bandwith available for user traffic. Location area in current systems is consist of static and arbitrarily-definded collections of cells, which do not take into account individual subscriber mobility patterns, either in space or time. A location management algorithm is proposed which uses the mobility history of individual subscriber to dynamically create individualized location areas, based on previous movements from cell to cell. The average duration spent in each visited cell is also maintained and is used to define paging which are most likely to contain the subscriber. And we propose a location management scheme which operates adaptively according to the speed of mobile station. It could be seen from analysis results that the signalling traffic for the registration and paging could be significantly reduced by using the proposed location management scheme.

PACS 시스템의 문제점과 개선방향

The PACS is very efficient system in the hospital, but the implementation of PACS and teleradiology still seem to have many problems to solve. In particular, the cost of such a system will not be overcome as soon as other factors such as image quality and transmission throughput rate. And other problems are the technical diffculties, the lakes of understanding about the PACS and inefficient communication networks in our country. In order to archieve the sucessful PACS, we must improve the problems as flowing : 1. We must follow the international standards on communication protocol and file format. 2. Because PACS promote a health of the people, it is necessary to provide the political support, installation grant-in-aid support, etc. 3. It is necesssary to make a related legislation. 4. We must accumulate a store of technology about the PACS and cultivate men of talent. we needs to make a requirements for good PACS and to evaluate in terms of clinic and engineering after PACS installation.

본 논문은 무선링크 환경에서 VoIP(Voice Over Internet Protocol)서비스를 효율적으로 지원하는 방안에 대하여 다룬다. 특히, 본 논문에서는 무선 링크의 할당 방식에 따른 VoIP 지원시의 장점과 단점을 고려하였다. 그 결과 VoIP 지원 시에 패킷 교환 방식이 몇 가지 점에서 더 유리한 방법이라는 결론을 내렸다. 그리고 무선 상에서 성공적인 VoIP 서비스를 제공할 수 있도록 몇 가지 주요 요구사항들을 제안하였다. 또한 무선 채널을 효율적으로 이용하는 VoIP 적응 계층인 VoIP CP(VoIP Convergence Protocol)를 제안하고, 이것에 대한 성능 분석 및 평가를 하였다. 결과에 의하여 ITU-T G.723 처럼 긴 싸이클의 Voip 보코더 CODEC을 사용하는 것이 VoIP 동시 사용자의 수를 늘리는데 훨씬 유리한 것으로 나타났다. 이 경우, 시스템의 동시 사용자가 회선 기반 방식보다는 거의 60% 이상 증가하는 것으로 나타났다. In this paper, we consider pits and falls of V oIP service scheme over the air link environment. It results that V oIP over packet switching is a more attractive approach in several points. We point out the ffilIior requirements for successful V oIP service over the air. Also, we propose V oIP CP concept for efficient wireless channel utilization. Additionally, we analyze and evaluate the performance. According to the results, It shows that the long cycle VolP vocoder CODEC such as ITU-T G.723 is better than short cycle V oIP vocoder CODEC. In this case, the increase of the simultaneous user of system is almost 60% larger than conventional circuit switching.

In this paper, we consider merits and demerits of VoIP service support approach over the air link environment. And, we decide that VoIP over packet switching is a more attractive approach in several points. Then, we point out the major requirements for successful VoIP service over the air link. Also, we propose VoIP CP concept for efficient wireless channel utilization. And, we analyze and evaluate the performance. According to performance results, we show that VoIP over wireless network based on packet switching could give a performance improvement of increased VoIP subscribers at simultaneous time or improved data service capability by re-using silence period of voice service.
