Published: January 2025

Os danos causados ao longo prazo em pacientes com COVID-19 resultaram em efeitos físicos e psicofisiológicos, tornando de extrema relevância na fase pós-aguda a ocorrência da reintegração social pós cura pela contaminação do novo coronavírus, como também para aqueles que desenvolveram o quadro leve da doença. A reabilitação é um elemento primordial para uma boa recuperação seguida da alta de doenças e diversas complicações de saúde. Até então não se sabe todos os malefícios físicos a longo prazo do novo coronavírus, no entanto, existe uma concordância acerca dos efeitos adversos decorrentes da ventilação mecânica, sendo uma delas, a síndrome pós cuidados intensivos. O presente estudo revisou artigos que abordassem a reabilitação em pacientes que foram infectados pelo COVID-19, com o objetivo de conhecer as sequelas no período pós doença. Trata-se de uma revisão integrativa de literatura com abordagem qualitativa. A procura nas bases de dados se deu através do método de busca avançada e utilizando como estratégia de investigação o cruzamento entre os Descritores em Ciências da Saúde e os operadores booleano AND e OR: (coronavírus OR SARS-CoV-2 OR COVID-19) AND reabilitação. A análise dos artigos selecionados demonstrou que os pacientes pós-cura da COVID-19, que foram acometidos pela forma leve a moderada da doença, exibiram principalmente dispneia, fadiga, anosmia e hiposmia. Os artigos que abordaram os pacientes pós-tratamento intensivo para a COVID-19, demonstraram que os danos relatados após a cura são bastante diversificados, tendo em vista a abrangência multissistêmica da doença. Desse modo, cada uma das publicações trouxe considerações diferentes, embora algumas delas tenham se apresentado de modo mais frequente, não podem ser agrupadas em um padrão clínico, levando em conta que o comprometimento de um sistema pode acarretar inúmeras disfunções diferentes. Nosso estudo evidenciou que os pacientes pós-covid-19 podem desenvolver disfunções em quase todos os sistemas de órgãos, no qual foi visto que o fornecimento de uma reabilitação adequada e individualizada apresentou efetividade e bons prognósticos relacionados aos desfechos clínicos dos pacientes.
An Algorithm for Synthesizing Groups of Codes in an RFID Multiple Access System
Authors: Verzun N. A. , Kolbanev A. M. , Kolbanev M. O. 
Published: January 2025

Relevance. One of the problems that must be solved when creating RFID systems is the reader's multiple access to a group of tags located in a limited space, since the reading signal causes a one-time response of many tags, which leads to collisions (conflicts) of response signals. This problem has not been solved in relation to passive tags without a chip, based on surface acoustic wave technologies, the code of which is laid down during manufacture and cannot be changed during operation. The purpose of the study is to develop algorithms that allow synthesizing such groups of codes that would provide a controlled level of pairwise correlation of the selected label signals and thereby ensure the specified accuracy of label identification. The proposed algorithms are based on the procedures of code concatenation and inductive construction of groups of codes with a given volume and correlation level. For the algorithm for forming a group of codes with the required value of the correlation coefficient and the algorithm for combining groups of codes into complete and maximum groups, properties have been proven that confirm the possibility of using them to formulate tasks for preparing groups of labels on surfactants that would correspond to the number of objects requiring identification and the accuracy of their identification and taking into account the number of labels in the group, the conditions for the propagation of radio signals in the area of operation of the reader, the number of repeated readings of the label codes, as well as algorithms for joint data processing, received with all calculations.The methods used. Methods of coding theory and correlation analysis. Result. The developed algorithm is a tool for creating modern coding systems for surfactant labels. The scientific novelty. Well-known algorithms for multiple access in RFID systems are proposed in the GEN1 and GEN2 EPC Global standards, and assume that the tag has a chip and a power supply, which makes it possible to implement protocols for influencing the tag with a reader using special commands. The proposed multiple access algorithm is applicable for passive surfactant tags, including those moving at high speed and/or located in aggressive environments, since the tags do not use silicon technology compared to active RFID tags. Practical significance. The use of the proposed set of algorithms will increase the efficiency of marking systems by reducing the identification time of objects located in a confined space.

Actuality. The current paper is the second part of the paper “Advance in Applied Cryptography Theory: Survey and Some New Results. Part 1. Key Cryptography” published in the journal PTU, n.4, 2024. It is devoted to such specific area of applied cryptography as keyless one (KC\ Actuality of the current paper consists in the fact that considered in it methods allow to provide a confidentiality of information transmission over public communication channels, either without any its encryption in advance, executing a natural properties of communication channels or executing conventional key cryptography but with the keys which are elaborated before by means of KC. The natural properties of communication channels can be the following: additive noise, multiray wave propagation, MIMO technology and existence of feedback channel.Our paper starts with a consideration of Wyner’s concept of wire-tap channels and corresponding to it encoding and decoding methods providing very reliable information transmission over the main channels and negligible amount of information leaking over the wire-tap channels to eavesdroppers. Next it is investigated scenario with a commutative encryption (CE) and corresponding protocol of message exchange over ordinary noiseless public channel that provides security of encrypted information but without any key exchange between users in advance. It is proved which of well known symmetric and asymmetric ciphers are commutative or non-commutative ones. Next model concerns a fading channels under the application of Dean-Goldsmith protocol in frames of MIMO technology. We are proving that this protocol is secure if, and only if, the number of eavesdropper antennas is less than the number of antennas at legitimate users. Next scenario executes variable directional antennas (VDA) and it is proved for which conditions on a locations of legitimate users and eavesdroppers such approach occurs secure given the number of propagation rays is at least two.. We show in the next chapter that there is an attack compromising of recently proposed EVESkey cryptosystem and hence such one is not secure in spite of the statement of its authors.Finally, we investigate several protocols intended for key sharing over noiseless constant public channels (like Internet) and established that they are mostly insecure because have all zero secret capacity. Only one protocol based on matrix channel exchange is able to provide security of key sharing but in terms of the required breaking complexity. Thus such approach can be used only for the case when legitimate users belong to low level of security requirements.At the end of the paper we formulate several fundamental problems of applied cryptography which after of their solutions could be very useful for practice.
System for Statistical Measurement of Atomic Efficiency for Graphical Interface Elements
Authors: Kurta P. A. 
Published: January 2025

Relevance. Currently, the interfaces quality often plays a decisive role in solving problems by a person using information services. To evaluate interfaces, the efficiency concept was previously introduced, consisting of the following indicators: effectiveness ‒ a conditional errors number measure when working with an information system; efficiency ‒ the speed of the user's work with the information system to obtain the desired result; 3) resource efficiency ‒ the degree of user psycho-emotional stress when entering and processing data. Nevertheless, the previously obtained model requires not only the mathematical apparatus usage to determine such indicators, but also knowledge of the graphic elements atomic (i.e. individual or isolated) efficiencies associated with the features of the user's interaction with them.The article purpose is to improve the efficiency of information service interfaces, which requires calculating the individual graphic elements atomic efficiencies.The proposed solution essence is the visual system for statistical measurement of the atomic efficiency for 6 graphic elements (text field, drop-down list, classic and checkbox button, bidirectional counter and "slider") based on the performing various tasks results by users with their help. For example, the text field efficiency compared to a drop-down list will be higher for short words ‒ since their input from the keyboard is faster than selecting from the list, but lower for long sentences ‒ since in this case it is faster for a person to select the desired one than to provide correct input. The measuring principle the efficiency by the proposed system is based on the sequential output of graphic forms with different types (and in some cases, quantities) of elements, indicating the task to the user and measuring the correctness and data entry duration. To reduce subjectivity in actions, various techniques are used, such as different duration timers. A special survey at the end of the element test groups is used to assess the psycho-emotional load. The system has an implementation as a Web site in PHP, individual Web pages of which and their interpretation are given in the article. Experiments with the use of this system for 50 users allowed us to obtain the desired all elements atomic efficiencies.The scientific novelty of the solution lies in the obtaining possibility estimates of the interface elements efficiency in a completely formal way, taking into account only the features of user interaction with them, as well as the data specifics (size, type).The theoretical significance lies in expanding the class of methods for assessing the graphical interfaces efficiency obtained through assessing the elements that make it up.The practical significance lies in the possibility of directly using the obtained atomic efficiencies graphs to compare interfaces and optimize them.

Pemerintahan mengalami perkembangan yang pesat dalam bidang teknologi untuk mempermudah penyebaran informasi kepada masyarakat melalui media digital. Teknologi digunakan oleh pemerintah Kabupaten Sumbawa melalui implementasi E-Government. Namun, adanya digitalisasi yang digunakan pemerintah menemui hambatan dimana dalam masyarakat masih banyak yang mengalami digital divide terutama bagi masyarakat yang tinggal di wilayah pedesaan. Hal ini menjadi tantangan bagi Pemerintah agar persebaran informasi dapat dirasakan oleh seluruh masyarakat di Kabupaten Sumbawa. Penelitian ini menganalisis tipe digital divide yang dialami oleh masyarakat Kabupaten Sumbawa dengan menggunakan dimensi digital divide dari Szilard Molnar yang terdiri dari kesenjangan akses, kesenjangan penggunaan, serta kualitas dari penggunaan. Penelitian ini mencoba untuk mengidentifikasikan bagaimana masyarakat menggunakan teknologi informasi dan hambatan apa yang dialami masyarakat selama menggunakannya. Metode penelitian yang digunakan adalah kualitatif dengan tujuan agar data yang diperoleh dapat ditelusuri lebih dalam. Informan berasal dari beberapa bidang di Dinas Komunikasi Informatika Statistik dan Persandian Kabupaten Sumbawa, dan masyarakat desa yang terdampak digital divide. Hasil dari penelitian ini menunjukkan bahwa dari dimensi digital divide yang digagas oleh Molnar diperoleh data bahwa masyarakat pedesaan cenderung mengalami access divide yang disebabkan oleh persebaran jaringan yang tidak merata, masyarakat mengalami masalah pada usage divide dikarenakan keterbatasan masyarakat dalam memiliki perangkat elektronik, masyarakat juga terkendala keterbatasan skill atau kemampuan dalam menggunakan perangkat elektronik sehingga tidak dapat memaksimalkan manfaat yang di dapat dari penggunaan perangkat elektronik. Dari beberapa kendala diatas, pemerintah memiliki peran dalam mengentaskan digital divide agar E-Government dapat berjalan dengan baik.

Published: January 2025

The variables affecting Thai voters living in the United States in their support for Pitha Limcharoenrat are investigated in this paper. Using data from 396 respondents gathered via an online poll, it emphasizes the roles of political problems, media impact, and public opinion, therefore reaching a distributed demographic efficiently. Multiple regression was used in the analysis, and the JAMOVI program was used to achieve a robust model fit (R2 = 0.583). This model fit accounts for 58.3% of the variance in voter support. It was found that public opinion was the most influential predictor among the factors (normalized value = 0.457), followed by the influence of the media (0.297) and political problems (0.117s). These results highlight the need of public opinion and media coverage in forming political support among the Thai diaspora in the United States, therefore providing insightful information for policies meant to involve expatriate populations.

Effects of aging-related muscle degeneration on dynamic stability during walking: a musculoskeletal computer simulation study
Authors: Kudo Shoma , Fujimoto Masahiro , Nagano Akinori 
Published: January 2025

IntroductionAging-related deficits in the physiological properties of skeletal muscles limit the control of dynamic stability during walking. However, the specific causal relationships between these factors remain unclear. This study evaluated the effects of aging-related deficits in muscle properties on dynamic stability during walking.MethodsWalking movements were simulated using two-dimensional musculoskeletal models consisting of 18 Hill-type muscles. To assess the effects of aging-related deficits in muscle function on dynamic stability during walking, five models with different muscle properties were created, namely young adult (YA) and older adult (OA) models, models with reduced maximum isometric muscle force, reduced maximum muscle contraction velocity, and prolonged muscle deactivation time (∆F, ∆V, and ∆T models, respectively). The margin of stability (MoS) was used as a measure of dynamic stability during walking.Results and DiscussionThe MoS value of the OA model was greater than that of the YA model, and the ∆F model yielded a larger MoS value than those of the ∆V and ∆T models. Therefore, the OA model achieved a more dynamically stable state than the YA model and the ∆F model required a more stable state to sustain continuous walking compared to the ∆V and ∆T models. These findings indicate that aging-related deficits in muscle function limit the control of dynamic stability during walking with the degeneration of maximum isometric muscle force being the most influential factor. These findings could aid in the development of an intervention program to reduce the risk of falls in older adults effectively.

Published: January 2025

BackgroundCoronary atherosclerotic heart disease (coronary heart disease; CHD) is the leading cause of death in women worldwide, and the number of patients and deaths is increasing each year. Approximately 3.8 million women die from CHD every year globally. After menopause, estrogen levels decrease, and the risk of cardiovascular disease increases substantially; however, research on risk factors for CHD in postmenopausal women has been inconclusive.ObjectiveTo systematically evaluate the risk factors for CHD in postmenopausal women.MethodsThe PubMed, Embase, Web of Science, CINAHL, CBM, CNKI, and VIP databases were searched up to February 9, 2024, for studies on risk factors for CHD in postmenopausal women. Two researchers independently screened the literature, extracted data, and evaluated the quality of the included literature. STATA17.0 software was used for meta-analysis.ResultsNine studies involving 29,4103 patients were included. The results of the meta-analysis showed that history of six or more pregnancies (hazard ratio = 1.538, 95% confidence interval: 1.241%–1.906%) was significantly associated with risk of CHD (P &lt; 0.05).ConclusionMultiple pregnancies are associated with CHD incidence and related mortality in postmenopausal women. In the future, more and higher quality studies are needed to further verify this conclusion.

BackgroundEffective management of dual antiplatelet therapy (DAPT) following drug-eluting stent (DES) implantation is crucial for preventing adverse events. Traditional prognostic tools, such as rule-based methods or Cox regression, despite their widespread use and ease, tend to yield moderate predictive accuracy within predetermined timeframes. This study introduces a new contrastive learning-based approach to enhance prediction efficacy over multiple time intervals.MethodsWe utilized retrospective, real-world data from the OneFlorida + Clinical Research Consortium. Our study focused on two primary endpoints: ischemic and bleeding events, with prediction windows of 1, 2, 3, 6, and 12 months post-DES implantation. Our approach first utilized an auto-encoder to compress patient features into a more manageable, condensed representation. Following this, we integrated a Transformer architecture with multi-head attention mechanisms to focus on and amplify the most salient features, optimizing the representation for better predictive accuracy. Then, we applied contrastive learning to enable the model to further refine its predictive capabilities by maximizing intra-class similarities and distinguishing inter-class differences. Meanwhile, the model was holistically optimized using multiple loss functions, to ensure the predicted results closely align with the ground-truth values from various perspectives. We benchmarked model performance against three cutting-edge deep learning-based survival models, i.e., DeepSurv, DeepHit, and SurvTrace.ResultsThe final cohort comprised 19,713 adult patients who underwent DES implantation with more than 1 month of records after coronary stenting. Our approach demonstrated superior predictive performance for both ischemic and bleeding events across prediction windows of 1, 2, 3, 6, and 12 months, with time-dependent concordance (Ctd) index values ranging from 0.88 to 0.80 and 0.82 to 0.77, respectively. It consistently outperformed the baseline models, including DeepSurv, DeepHit, and SurvTrace, with statistically significant improvement in the Ctd-index values for most evaluated scenarios.ConclusionThe robust performance of our contrastive learning-based model underscores its potential to enhance DAPT management significantly. By delivering precise predictive insights at multiple time points, our method meets the current need for adaptive, personalized therapeutic strategies in cardiology, thereby offering substantial value in improving patient outcomes.
