Abstract:

The paper presents the implementation of the patient medical digital passport, using distributed ledger for storing encrypted electronic health records, patient and medic digital entities and accesses for data. A system for the secure distributed storage of highly sensitive confidential medical data is described.

Abstract:

The presented web database on experimental homolytic bond dissociation energies in organic compounds is intended for use by a wide range of theoreticians and practitioners in free access. The paper provides a brief overview of the sources of the dissociation energies of bonds of organic molecules, which are calculated theoretically, measured experimentally and estimated from kinetic and thermochemical experimental data, their presentation in the Internet database. A web database on homolytic bond dissociation energies of organic compounds is presented. The reported bond dissociation energies are calculated from experimental kinetic and thermochemical data. Descriptions of experimental data sources, classes of organic compounds and calculation methods are given. The logical structure of the database and the description of the main fields of its tables are given. The main search form of the database interface is presented and an example of a search result for a specific organic compound is given. Bond dissociation energies are calculated at a temperature of 298.15 K, which is usually absent in most sources. The analogs of the present base are inferior to the latter in taking into account temperature correlations. Currently, work is underway to analyze and analyze the published data taking into account the entropy effects.

Abstract: Methods of the semantic documents parsing in digital control system of scientific collections, including electronic journals, offered. The methods of processing documents containing mathematical formulas and methods for the conversion of documents from the OpenXML-format in ТеХ-format considered. The search algorithm for the mathematical formulas in the collections of documents stored in OpenXML-format designed. The algorithm is implemented as online-service on platform science.tatarstan.

Abstract:

The paper is devoted to the development of an expert system for diagnosing pneumonia based on fuzzy logic and implemented using the Mamdani algorithm. The paper discusses the main stages of the system development, including fuzzification of input data, definition of fuzzy rules based on medical expert knowledge, aggregation of fuzzy inferences and their defuzzification to obtain the final diagnostic result. The web interface of the system is implemented using the Django framework, which ensures ease of interaction for users. The use of a medical expert system for diagnosing pneumonia can reduce the time required to establish a diagnosis and improve the quality of diagnosis by integrating the experience of medical experts and modern information technologies.

Abstract:

The paper is devoted to the study of the cognitive function associated with the generation of elliptical sentences in the Russian language. The study is conducted by testing this cognitive ability using a computer system specially developed by the authors for this purpose. Testing of this cognitive ability is proposed and implemented for the first time. The system is an extension of Moodle and is openly hosted in the github repository. Elliptical constructions are limited to verbal and nominal ellipses, which are theoretically possible to be completely reconstructed based on the context of the sentence. The study is conducted with the participation of SPbPU students as respondents. The texts of planimetric tasks are chosen as the subject area. As a result of the analysis of testing data, the following results are obtained: the influence of the respondent’s knowledge of the subject area (planimetry) on the test results is established; a tendency towards self-study of respondents was discovered, which is manifested in a reduction in time and an increase in scores as they pass tests; it is shown that respondents are poorly motivated if they do not see feedback on the answer to the completed task. The paper discusses the problems of further development of the testing system and its use in adapting questionnaires (tasks) to assess the knowledge of SPbPU students in the field of automation of bug detection in programs, as well as for diagnosing the functional state of operator specialists and express diagnosis of dementia. It also seems promising to use the system to improve the processes of syntactic parsing of elliptic sentences and automate the restoration of ellipses in the subject area of planimetry.

Abstract: There are three main ways of obtaining information: searching, browsing and alerting. The first two are being widely developed by libraries using the Web, but the last has been somewhat neglected. The NewsAgent for Libraries project was originally funded under the eLib Programme by JISC (Joint Information Systems Committee of the UK higher education funding councils) as a two-year collaborative project started in April 1996.
Several small publishers of library and information science journals worked with network specialists, market evaluators and commercial software developers to design an open, distributed architecture for disseminating information via email and personalised Web pages. Dublin Core metadata was used, enhanced by NewsAgent specific keywords, to map stored user subject profiles against information feeds. Metadata was harvested using software robots to build an Oracle database where both user profiles and document attributes were stored.
Users can join the service via a Web page, to receive information updates by email or as a personalised Web page. Users can select predefined Topics in which they are interested, or create new named ones (stored queries). They can also modify existing Topics. Topics are presented in groups, called Channels.
A major part of the project was an extensive study of the potential end users of the service, before and after a prototype service was created. The project was considered a success, although further development of both software and marketing strategy were needed before a full scale launch could be planned. This is now expected in autumn 1999. In addition to this service, the software is being applied to other services by different organisations, targetted at groups such as small businesses, medical information and environmental information. It is expected that a commercial software package will be available from Fretwell-Downing Informatics as a result of the project.
