Opis:
A new standard of still image compression is characterised in the context of medical applications. Wide spectrum of JPEG2000 features is analysed with respect to its application potential to improve the performance of modern medical services (i.e. telemedicine, PACS, radiology information systems, wireless personal/home health care systems). Image data security techniques, error resilience technologies, client-side interactive Region of Interest (ROI) transmission and decoding (e.g. for teleconsultation with very large radiography exams), and storage of multiple image data sets are considered in detail. Selected tests of coders realized according to parts I and II of JPEG2000 for different modality test images are presented to evaluate the compression efficacy of this standard. Exemplary results of encoding process optimisation by wavelet transform and subband decomposition selection and screen-shots of software interfaces designed for these tests are also presented.

Opis:
The Medical information systems evolve constantly. The quality of the medical information system relies on competences, qualifications, and the organization of the participating partners. Those last ones belong to heterogeneous and autonomous information systems. So, it is necessary to assure a permanent cooperation. This paper shows a coherent architectural framework that allows the development of interoperable medical information systems in measure or these systems evolve. The essential idea is to use concepts of multi-agent systems to perform the different activities of medical information system and thus, to adapt the solutions provided by the agent paradigm to solve the different problems encountered while establishing a medical information system.

Opis:
In the paper, the method of acoustic model complexity level selection for automatic speech recognition is proposed. Selection of the appropriate model complexity affects significantly the accuracy of speech recognition. For this reason the selection of the appropriate complexity level is crucial for practical speech recognition applications, where end user effort related to the implementation of speech recognition system is important. We investigated the correlation between speech recognition accuracy and two popular information criteria used in statistical model evaluation: Bayesian Information Criterion and Akaike Information Criterion computed for applied acoustic models. Experiments carried out for language models related to general medicine texts and radiology diagnostic reporting in CT and MR showed strong correlation of speech recognition accuracy and BIC criterion. Using this dependency, the procedure of Gaussian mixture count selection for acoustic model was proposed. Application of this procedure makes it possible to create the acoustic model maximizing the speech recognition accuracy without additional computational costs related to alternative cross-validation approach and without reduction of training set size, which is unavoidable in the case of cross-validation approach.

Opis:
In the paper, the method of short word deletion errors correction in automatic speech recognition is described. Short word deletion errors appear to be a frequent error type in Polish speech recognition. The proposed speech recognition process consists of two stages. At the first stage the utterance is recognized by a typical speech recognizer based on forward bigram language model. At the second stage the word sequence recognized by the first stage recognizer is analyzed and such pairs of adjacent words in the recognized sequence are localized, which are likely to be separated by a short word like conjunction or preposition. The probability of short word appearance in context of found words is evaluated using centered trigrams and backward bigram language model for short words prone to deletion. The set of probabilistic language properties used to correct deletions is called here Local Bidirectional Language Model (in contrast to purely forward or backward model used typically in speech recognition). The decision of short word insertion is based on comparison of deletion error probability of the first stage recognizer and the error probability of the decision based only on centered trigrams and backward model. Despite its simplicity, the method proved to be effective in correcting deletion errors of most frequently appearing Polish prepositions. The method was tested in application to medical spoken reports recognition, where the overall short word deletion error rate was reduced by almost 45%.

Opis:
The article presents the method of building compact language model for speech recognition in devices with limited amount of memory. Most popularly used bigram word-based language models allow for highly accurate speech recognition but need large amount of memory to store, mainly due to the big number of word bigrams. The method proposed here ranks bigrams according to their importance in speech recognition and replaces explicit estimation of less important bigrams probabilities by probabilities derived from the class-based model. The class-based model is created by assigning words appearing in the corpus to classes corresponding to syntactic properties of words. The classes represent various combinations of part of speech inflectional features like number, case, tense, person etc. In order to maximally reduce the amount of memory necessary to store class-based model, a method that reduces the number of part-of-speech classes has been applied, that merges the classes appearing in stochastically similar contexts in the corpus. The experiments carried out with selected domains of medical speech show that the method allows for 75% reduction of model size without significant loss of speech recognition accuracy.

Opis:
In the paper a method of optimal selection of utterances used as command entry-words for voice controlled application is presented. Voice controlled programs seem to be particularly useful in the area of medical informatics, where a physician interacts with a program by voice while operating the medical device or being involved in examinations requiring manual activities. The proposed method selects command words from sets of proposals defined for each command so as to minimize the overall probability of incorrect command recognition. First the entry-word dissimilarity matrix is calculated. The word dissimilarities are evaluated using HMM models consisting of appropriately trained acoustic models of the phonemes constituting words. The trained HMM is used as the sample utterance generator for the word. The artificially created utterance samples are then recognized by speech recognizers created for pairs of words. The estimation of correct recognition probability is used as the word dissimilarity measure. The word dissimilarities are then used to determine the average assessment of words selections that can be used as commands. Selection is created by choosing single word from sets of candidates defined for each command. Finally, suboptimal selection is found by using genetic algorithm. Experiments carried out prove that suboptimal selection of command entry-words can observably increase the accuracy of spoken commands recognition in many cases.

Opis:
Reports by institutions monitoring this market show that of over PLN 7 billion spent annually in Poland on advertising, almost half is spent on advertising OTC medicines, medical devices and dietary supplements (Instytut Monitorowania Mediów, 2019). Considering this, and taking into account legal regulations that significantly limit promotion at the point of sale (Art. 93 of the Pharmaceutical Law Act), advertising seems to be the most important tool for stimulating demand for over-the-counter products as well as one a basic source of of the residents of Poland on ailments, their treatment and prevention. The study examined 71 advertisements, including 47 ads for medicines, 10 for medical devices, 12 for dietary supplements and 1 ad for food for special medical purposes. Among the sample, 27% ads contained manipulation in the marketing message. The current tools of market control institutions enable the analysis of explicit claims but not implied messages in advertising. Our analysis shows that this is not enough to protect patients and other market participants from misleading or false advertising. It is absolutely necessary to enhance the control over the advertising of medicines, dietary supplements and medical devices by analysing the implications contained in the advertisements.
Analizy instytucji monitorujących ten rynek wykazują, że z ponad 7 miliardów złotych rocznie wydawanych w Polsce na reklamę, blisko połowa przypada na reklamę leków OTC, wyrobów medycznych i suplementów diety. W związku z tym oraz regulacją prawną znacznie ograniczającą promocję w miejscu sprzedaży (Art. 93 Ustawy Prawo farmaceutyczne) reklama produktów farmaceutycznych wydaje się najważniejszym instrumentem pobudzania popytu na produkty dostępne w aptekach bez recepty oraz podstawowym źródłem wiedzy mieszkańców Polski na temat dolegliwości i ich leczenia oraz profilaktyki. Badaniu poddano 71 badanych reklam: 47 z nich to reklamy leków, 10 – wyrobów medycznych, 12 – suplementów diety i 1 żywności specjalnego przeznaczenia medycznego, aż w 27% stwierdzono manipulację przekazem marketingowym. Obecne narzędzia instytucji kontroli rynku umożliwiają analizę treści eksplikowanych, ale nie implikowanych przez reklamę. Przeprowadzona analiza wykazuje, że nie wystarcza to, aby zabezpieczyć pacjentów i innych uczestników rynku przed nieuczciwą reklamą. Bezwzględnie konieczne jest uzupełnienie nadzoru nad reklamami leków, suplementów diety oraz wyrobów medycznych o analizę imlikatur zawartych w reklamach.

Opis:
Internet of medical things (IoMT) network design integrates multiple healthcare devices to improve patient monitoring and real-time care operations. These networks use a wide range of devices to make critical patient care decisions. Thus, researchers have deployed multiple high-security frameworks with encryption, hashing, privacy preservation, attribute based access control, and more to secure these devices and networks. However, real-time monitoring security models are either complex or unreconfigurable. The existing models’ security depends on their internal configuration, which is rarely extensible for new attacks. This paper introduces a hybrid metaheuristic model to improve healthcare IoT security performance. The blockchain based model can be dynamically reconfigured by changing its encryption and hashing standards. The proposed model then continuously optimizes blockchain based IoMT deployment security and QoS performance using elephant herding optimization (EHO) and grey wolf optimization (GWO). Dual fitness functions improve security and QoS for multiple attack types in the proposed model. These fitness functions help reconfigure encryption and hashing parameters to improve performance under different attack configurations. The hybrid integration of EH and GW optimization models can tune blockchain based deployment for dynamic attack scenarios, making it scalable and useful for real-time scenarios. The model is tested under masquerading, Sybil, man-in-the-middle, and DDoS attacks and is compared with state-of-the-art models. The proposed model has 8.3% faster attack detection and mitigation, 5.9% better throughput, a 6.5% higher packet delivery ratio, and 10.3% better network consistency under attack scenarios. This performance enables real-time healthcare use cases for the proposed model.
