and students of the system using the resources of URAN. The methodology of distance learning is based upon the principles of shells. In such shells systems, which have their own internal structure and connections, only the content part of the shells changes, namely, information. Despite a variation in information other general system models of the shell do not change. At present there are 15 regional nodes of distance learning in the Ukraine, which are connected in the integrated medium by means of the URAN system.
The third segment of the Ukrainian information portal provides access to the electronic information resources of science and education in accordance with the three levels of the computer network—Internet, intranet, and corporate networks. This segment is connected to regional laboratories with remote access to information resources in the fields of economics and management, ecology, medicine, biology, physics, mathematics, modeling of complex processes, telemedicine, and other fields. These resources include online electronic libraries from various organizations, universities, academic institutions, the Ukrainian National Academy of Sciences, public libraries, and distance learning centers. The network of online electronic libraries includes library resources in scientific and educational fields. The system is built upon unified operational software, hardware, and technical platforms.
The fourth segment of the informational portal is a national educational information system called OSVITA. This system solves the educational management problems, such as the problems of automation of information collection and processing and the collection of state documents on education. OSVITA is a complex grouping of administrative legal, software, and hardware facilities. The system makes it possible to create a unified information infrastructure to process data on education, preserving their validity and integrity, and providing reliable information protection mechanisms. The OSVITA system ensures that complex information production systems used to create state documents on education will function.
An application of the Ukrainian information portal involves solving the problem of ecological monitoring of the Chernobyl nuclear power plant, as well as the development of the telemedical channel for the diagnosis and treatment of those working at this plant. One of the problems is the necessity for continuous control over the area above the plant. There are a number of regional centers monitoring ecological conditions in the area. The continuous monitoring of ecological conditions in the Ukraine shows that the plant zone itself and considerable adjacent territories are still polluted with radioactive substances such as plutonium isotopes. Such complex industrial factors have no analogies from the point of view of their harmful impact upon human health.
The power engineering specialists working in the Chernobyl nuclear power plant live approximately 30 km from Chernobyl. There are 4,363 people working at the reactor. Of those, 1,375 are women. Practically all the inhabitants of the city are in contact with ionizing radiation conditions. More than 84 percent of the inhabitants suffer from the Chernobyl disaster. These people need special, high-quality medical service and exhaustive consulting assistance. The obstacle is insufficient technical equipment in patient care institutions and remoteness from the regional center.
The purpose of the monitoring system is also to analyze the state of health of various professional groups while taking into account the risk factors. The system will make it possible to work out individual programs of health recovery. The absence of such a system is one of the reasons that approximately 600,000 people have become invalids from the Chernobyl catastrophe. A number of measures aimed at protecting the plant’s personnel against harmful impacts and risk factors will be implemented. Medical monitoring is necessary to establish the expert diagnostic system and the system of remote transfer of the analysis and research data. It will make it possible to carry out consultations by means of telecommunication.
The Chernobyl telemedicine system consists of two centers. One is the diagnostic and rehabilitation center, which is situated in Slavutych City. It monitors the main medical factors of employees of the Chernobyl power plant and members of their families, in accordance with individual programs. These data are transferred by the URAN system to the international telemedicine center, which is located in Kiev, at the National Technical University of Ukraine—Kiev Polytechnic Institute. Highly qualified specialists in the field of medicine work in this center. They analyze the data obtained on each patient and work out recommendations for prevention and
