The advanced technology called "expert systems" can help solve many problems of developing countries; research workers say that its application to these problems is overdue. Expert systems are based on computers, which use information and reasoning techniques to solve problems that normally require human experts. They may rely on "artificial intelligence" software to help human experts do their work, to train new experts, and to provide some elements of expertise in situations where human experts are in short supply. For at least a decade, expert systems have proved themselves in developed countries, especially in agriculture, business, and primary health care. Can they help people in developing countries to improve their conditions or create wealth? This question is addressed, if not completely answered, in a newly published collection of papers. Health-care delivery, natural-resources management, and crop planning present challenges not only because their problems urgently need solving, but because they are complex enough to require expert judgement. In many developing countries with abundant supplies of underemployed educated persons, computers and computer-literacy are still uncommon. However, the rapid spread of microcomputers and electronic communications in all parts of the world is making it easier for people to use these powerful tools. In addition, the software for expert systems has become more affordable and user-friendly. Finally, in many countries survey databases are already available that can be used by expert systems; for example, in health-care financing in Rwanda and water-supply problems in Slovenia. T. W. Fermanian (University of Illinois, Champaign-Urbana) and R. S. Michalski (George Mason University, Fairfax, Virginia) list the features that make today's software so adaptable to the needs of developing countries: The programs not only accept rules of reasoning given by the user, but also infer new rules from the data and by "experience." They accept data and rules that have numerical probabilities or weighting associated with their use. They can be used on a personal computer. They have menu-driven screens. In addition, some programs reveal their reasoning on request, after solving a problem, thus providing valuable feedback to human experts, who can then further improve the reasoning rules. Examples: Dominican Republic, Ethiopia D. Mendez E. and S.V. Grabski (Michigan State University, East Lansing) are basing their agricultural studies on the Geographic Information System that is already well developed in the Dominican Republic. Their purpose is to help policy makers plan the best use of land for forests and food crops. Consider onions: they thrive best under certain conditions of soil pH, rainfall, temperature, drainage, etc.; the same kinds of information are part of the national geographic database. According to Mendez, the matching of crop and geographic databases "will be used when a farmer wants to know what crops a specific site is capable of supporting." Already the system has produced one benefit: it has demonstrated that the administrative boundaries of the country's agricultural regions have little relation to physical "agroecological" regions. Accordingly, the authors plan to use both kinds of mapping to help policymakers. The system now provides only feasibility analyses, but the next stage will include cost / benefit analysis. A sensitivity analysis to be developed will show how robust the answers produced by the expert systems are to changes in the underlying estimates. And every time a recommendation is implemented, the system will stored its outcome as part of its "experience." G. Porenta (University Hospital, Vienna, Austria) and colleagues are designing a decision support system to serve village health workers in Ethiopia. Diarrhea, worm infestations, eye disease, skin afflictions, and malaria make up about half of the daily work. Like most progams based on artificial intelligence, their software contains a large number of "if ... then" statements. For example, "if the patient is not a child," then ask "if a dry tongue is present." If so, then see a doctor. Symptoms are given weights to arrive at the treatment of choice. If several treatments-of-choice are indicated, the software selects the least costly. Porenta's program is based on particular assumptions about the environment: a highland region, civil war, poverty and famine, and closed rural-health centers. Transplanting the program to another region or country may require changing the assumptions. According to Porenta's team, the most important challenge now is to develop a more user-friendly, graphical interface. Other research workers are developing a health-related system in Chad. Practice and Promise In a summary chapter, V.S. Doherty, C.K. Mann, and J.J. Sviokla summarize existing knowledge about the use of expert systems in international development. First of all, they have found no case studies that clearly show success or failure of expert systems in this context. Indeed, all indications point to the critical need for field testing of the prototype systems that are described in the book's descriptive chapters. These systems were mainly developed under conditions in affluent countries, but the ready availability of microcomputers and expert software strongly suggests that developing countries can and should develop their own prototypes and test them in the field. Moreover, the low startup costs for installing expert systems should favor their local use; for example, by associations of farmers. In developing regions, expert systems can be used as a training aid, for expertise development, and to assist policy makers in articulating problems. According to Doherty, growth in the use of expert systems is favored by the investment that developing countries are making in computers and communications. This thoughtful and well edited book is based on a symposium held in Boston in 1988 and sponsored by the American Association for the Advancement of Science. In view of rapid developments, it is fortunate that several contributing authors have updated their papers and added current references. Of the 13 research chapters, one concerns water analysis, one is on enterprise development, three are on health-related systems, and the rest are related to agriculture. Charles K.

Expert Systems in Health for Developing Counbtries Dayo Forster: `Expert Systems in Health for Developing Countries: Practice, Problems and Potential' May 1992 ISBN: 0-88936-637-3 Manuscript report published by the International Development Research Centre (IDRC), Ottowa (64 pages) Dr Forster was commissioned by the IDRC to do a survey on expert systems in health care for developing countries as a follow-on from her related thesis work. This is a review of several expert systems for health in developing countries. The document examines 15 pieces of software and the author has compiled a bibliography of more than 150 articles and pieces on this and related areas. More than half the document is devoted to two very useful lists; the large bibliography and a list of people throughout the world connected with this area. Medical Informatics in Brazil (Reproduced from mailing list SMDML without permission) The Center of Biomedical Informatics is an interdisciplinary research center affiliated to the State University of Campinas (UNICAMP). AIMS The Center of Biomedical Informatics has the following aims: - to promote interdisciplinary research and development in all fields related to the application of Informatics to the Biological and Health Sciences; - to promote specialized training and education in these areas, by means of courses and graduate programs in collaboration with other UNICAMP units; - to make available and to extend this knowledge to the participating and user's community, through publications, seminars, technical consultancy, etc. The Center of Biomedical Informatics has played a leading role in the development and progress of Health Informatics in Brazil. Its members were instrumental in forming the first professional society in the area (the Brazilian Society of Health Informatics), its first and only journal (Brazilian Journal of Health Informatics), in organizing and hosting the First Brazilian Congress of Health Informatics (Campinas, 1986), and in actively helping federal, state and research/higher education and research granting agencies in setting up programs in the area. RESOURCES Currently, NIB has a staff of 2 full-time researchers, 5 associated researchers, 3 full-time systems analysts and 2 administrative assistants. There are an additional 20 persons involved with NIB activities, including other investigators, undergraduate and graduate students, etc., associated to ongoing research projects. NIB is located in a building belonging to the huge in-campus complex comprising the 1,000-student Medical School and the 500-bed University Hospital complex. The majority of projects within NIB are oriented towards practical applications of microcomputers to health care and research. NIB is connected to the University's Computing Center facilities, which are one of the most advanced in the country. They consist of a cluster of four high-performance Digital VAX mainframes, a Cyber 700 and an IBM 3090 mainframe with a 300-mips vector facility, all connected to a local optical fiber Ethernet network which integrates other VAX and IBM superminicomputers located in several Institutes. RESEARCH AND DEVELOPMENT The most important areas of research and development at NIB are: - hospital and laboratory automation; - general clinical applications (history-taking, clinical database management, health risks appraisal, medical decision-making); - scientific applications in several areas (neurology and neurobiology, cardiology, anesthesiology, ophthalmology, internal medicine, dentistry, nursing, intensive therapy, obstetrics and gynecology, etc.) - computer-assisted health education and training, and teaching of Informatics to health students and professionals; including intelligent CAI, hypertext and hypermedia applications - biological image and signal processing - knowledge engineering, intelligent data bases in Health, expert systems and neural networks applications in Biology and Medicine. The main line of excellence of the Center's research is devoted to applications in the Neurosciences. Many of the Center's research and development projects are carried out in close collaboration with other Departments and Centers in or outside UNICAMP, including the Medical, Dentistry and Nursing Schools, the University General Hospital, the Institute of Biology, the School of Physics Education, the School of Electrical Engineering, the Institute of Mathematics, Statistics and Computer Science, the Biotechnology Center, the Center of Informatics in Education, etc. TRAINING AND EDUCATION NIB offers regularly many lectures, courses and technical seminars to students and users in the health care area, both internal and external audiences. Some of the courses described below have been given in programs of permanent collaboration between NIB and several professional and scientific associations in the health sector, such as the Medical Association of Sao Paulo, the Dentistry Association of Sao Paulo, the Brazilian Nursing Association, etc.: - Basic and Advanced Concepts in Health Informatics; - Utilization of Microcomputers in the Clinical Practice - Applications of Computers in Nursing - Applications of Computers in Dentistry - Introduction to Computer Programming in the Health Sciences - Applications of Microcomputer Database Management Systems in Health Care - Medical Applications of Image Processing - Microcomputer Applications in Data Processing and Analysis in the Health Sciences - Artificial Intelligence Techniques and Applications in Medicine - Artificial Neural Networks in Medicine - Applications of Computers to Medical Education Starting 1986, an intensive Summer Course on Health Informatics has been offered to participants coming from other Brazilian Universities, with the aim to disseminate the Center's experience in setting up R and D centers in Health Informatics. The Center provides also the main support to the Chair of Medical Informatics at the School of Medicine, which is responsible for courses at undergraduate and graduate levels to Medical and Nursing students, since 1988. At international level, NIB has collaborated with the World Health Organization (Division of Information Systems Support) in developing teaching materials and in providing faculty resources to seminars and courses on microcomputer applications to health care management. In order to provide better opportunities for specialization studies in Health Informatics, the Center has established a collaborative program with the Medical and Engineering Schools at UNICAMP, designed to attract undergraduate students of Medicine, Nursing, Dentistry, etc., who are interested in a long term career in this area. Training is carried out through special courses developed by NIB, and by supervised research work on an individual basis. The students who show a higher potential are supported by state- granted fellowships until they graduate. There are currently 5 students enrolled in the Centaur Project. Finally, there is an ongoing collaboration between NIB and other University faculties, with the aim of forming specialists in Health Informatics, at the graduate level. There are currently 6 candidates preparing their Masters and doctoral dissertations under this program. Preparations are also being made to establish an autonomous, separate joint graduate studies program in Health Informatics, which will lead to a Masters degree. DOCUMENTATION AND INFORMATION SUPPORT With the aim to provide services of information support and documentation to researchers, lecturers, students and end- users in Health Informatics at a national level, NIB has established a clearinghouse and a central library facility with books, journals, product specifications and folders, technical manuals, software listings, etc. A national, public-domain software library for microcomputers has also been formed (MEDSOFT), and already includes a great variety of application software packages in health care and administration, which are distributed to users under a nominal cost. Some of these materials (software and bibliographic references, as well an information service about new products, congresses, new publications, etc.) are also disseminated to end-users through electronic mail. Finally, the Center's staff is responsible for the editing and publishing, in a joint effort with a private publisher, of the Brazilian Journal of Health Informatics, which is the only publication of its kind in Latin America, and is sponsored by the Brazilian Society of Health Informatics.

Networking in Africa (Reproduced from newsgroup soc.culture.african without permission) Tony Putnam (tonyp@ucthpx.uct.ac.za) writes: Electronic networkers from all over Africa, with providers of support from the more technologically-developed countries, took part in a workshop last month in Toronto, Ontario, Canada to discuss future developments of the fast-growing use of electronic mail in Africa. Many of the participants were operators of Fido systems. Fido is a distributed networking system running on personal computers that collect messages automatically during regular calls to a "host" computer (like IGC). Fido users may then read and respond to their messages at leisure "offline." Responses are collected and sent during the next call to the host. Messages are compressed into "packets" and sent using the most efficient means possible, given poor telephone lines. Over the last eighteen months, Fido has emerged as one of the predominant technologies providing electronic networking in Africa, especially where UUCP-based systems (a more traditional means of computer networking) are unavailable. There are now gateways between Fido and APC networks, for both mail and conferences, and there are several well-established Fido-based networks that are working closely with the APC. The Toronto workshop was very successful, covering both technical and organisational aspects and laying the foundations for solid growth based on the existing networks. Fido hosts connecting to APC gateways on GreenNet and Web (Canada) are already operating in Senegal, Kenya, Burkina Paso, Egypt, Uganda, Tanzania, Ethiopia, Ghana, Zimbabwe, South Africa, and Zambia. It is expected that this will expand to forty African countries within the next three years.
