UTMB is developing with industrial partners the "24/7 telemedicine triage project" to provide emergency medical care to offshore oil and gas rigs and platforms in the Gulf of Mexico. The oil and gas industry is second only to the US department of defense in the number of employees stationed in remote areas. Providing medical care to such populations is logistically complex and expensive. In addition, emergency evacuation is often time-consuming and poses risks for both patients and medical crews. By utilizing high-resolution videoconferencing technology, through a satellite communication, patient visits will be conducted in real time and will provide more informed decisions about the need for more extensive treatment, thereby reducing unnecessary evacuations. In addition, patients who require evacuation will receive a higher standard of care while waiting for transport to a medical facility. UTMB physicians report that 39% of all patients from offshore facilities treated in the emergency department, could have been successfully treated through telemedicine without being evacuated to a hospital. The telemedicine project will employ standard procedures for medical triage, in which patients are directed to appropriate medical experts based on their symptoms or type of injury.

Legal Aspects and Clinical Outcomes: Future Challenges in Telemedicine
This invited paper aims to examine how telemedicine and e-health will develop over the coming years and, in particularly, to assess what legal and ethical barriers may lie in the way of this development. A description of the key principles and concepts involved in telemedicine and e-health and a short historical overview of their evolution over the past century is followed by consideration ofwhy empirical research into "Info-ethics" and other deontological and legal issues relating to telemedicine and e-health are so important. Five evolving health telematics applications are examined in some detail: electronic health records; the transmission of visual media in disciplines such as teleradiology, teledermatology, telepathology and teleopthalmology; telesurgery and robotics; the use of call centres and decisionsupport software and, of course, the growing role of the Internet in healthcare. These are discussed in the light of their moral, ethical and cultural implications for clinicians, patients and society at large. Telemedicine and e-health present unique opportunities for both patients and clinicians where they are implemented in direct response to clear clinical needs. But excessive reliance upon technology will damage the traditional clinician-patient relationships and we must therefore avoid complacency regarding the risks and responsibilities - many of which are as yet unknown - that distant medical intervention, consultation and diagnosis carries.

There are a number of challenges that have to be addressed before full-scale implementation of telemedicine technologies can be achieved. These challenges include cost and resource concerns, technical issues, legal issues, lack of awareness of telemedicine and, previously unsuccessful trials using telemedicine technology. This paper will address these challenges and suggest ways in which they can be overcome. The "MEDASHIP" project is an example of the highly beneficial potential that telemedicine can have providing that the challenges referred to in the first part of this paper are addressed. "MEDASHIP" ("Medical Assistance for Ships") is a European Commission co-funded project of 1 8 months duration running under the TEN-Telecom programme of the Directorate General for the Information Society. The project will result in the formation of a European company that will supply integrated solutions for medical consultations on board passenger ships, cruise ships and merchant vessels. The MEDASHIP project aims to address the wide disparities that still exist between the medical care available to European citizens when working or travelling at sea and that available on land as well as to increase the competitiveness of the European cruise industry as compared to American flagged-vessels, which are already using the improved standards of medical care available to passengers through telemedicine as a crucial tool in marketing their cruises.

The performance of high-speed non-directed diffuse indoor infrared wireless communication is mainly affected by intersymbol interference (ISI) due to multipath dispersion. The direct-sequence spread spectrum systems are applied to combat multipath dispersion. However, when the data rate is close to the channel 3dB bandwith, the spread spectrum technique may have a worse performance than OOK transmission as it is affected by more severe ISI. Exploiting muli-spot link, we can improve the performance of spread spectrum technique to be much better than OOK modulation because a higher channel bandwith are obtained. Both the analytical and simulation results are presented.

General Packet Radio Service (GPRS) is a new service designed for digital cellular network (GSM, PCS, etc.). Due to its high efficiency on radio resource and "always on" mobility, GPRS has been widely adopted all over the world. So far, at least seven among the top 10 mobile operators have launched their GPRS services. Shanghai Mobile began its GPRS project in 1999. After well preparation, the Shanghai's commercial trial GPRS network was started in July 2001. During the trial, network performance has been carefully studied, so does customer behavior. By the end of 2001, GPRS network has fully covered Shanghai. In 17 May 2002, Shanghai Mobile announced to put its GPRS service into commercial use. In this paper, the development history of the cellular mobile communication in Shanghai is briefly reviewed first, and then the current GSM network status is offered. Further more, GPRS commercial trial is introduced. Finally some trial results are provided.
