Published: March 2024

Purpose of research. The purpose of this research is to develop an ontology structure as the basis of a database/knowledge base for selecting effective metaheuristic algorithms for solving the problem of load distribution in heterogeneous distributed dynamic computing environments, taking into account the overhead of data transmission over the network.Methods. The main scientific methods used in this study are domain analysis, methods for constructing subject ontologies, numerical optimization methods and computer modeling.Since the literature does not present resource allocation planning models that would take into account geographic distribution, the presence of intermediate data transmission routes, the dynamics of topologies and load, as well as system heterogeneity in terms of criteria for assessing the quality of load distribution, this article proposes a new model that takes into account these features. The complexity of solving a planning problem becomes one of the variable parameters, which has a significant impact on the planning result: with a decrease in the complexity of calculations, the result deteriorates accordingly. Therefore, a greedy strategy is proposed as a solution method: from the optimization methods to be considered, select the least labor-intensive one that would allow obtaining the best result in the allotted time. Test runs of simulated annealing algorithms demonstrate different effectiveness under different initial conditions of the problem; therefore, it is advisable for selected classes of problems to choose algorithms that are effective in terms of solution quality and labor intensity.Results. The result of the study is the structure of the ontology of effective algorithms. Also, the results are instances of simulated annealing algorithms and tasks included in the ontology, related by the “efficiency” relation.Conclusion. This article proposes the structure of an ontology of effective optimization algorithms and an approach to solving the problem of distributing the computational load, taking into account the complexity of the distribution procedure through the “greedy” selection of the most effective optimization algorithms.

Authors: Zheng Amy , Bergh Marissa , Patel Murali Komal , Sadarangani Tina 
Published: March 2024

Background
Adult day services (ADS) provide community-based health care for older adults with complex chronic conditions but rely on outdated methods for communicating users’ health information with providers. CareMOBI, a novel mobile health (mHealth) app, was developed to address the need for a technological platform to improve bidirectional information exchange and communication between the ADS setting and providers.

Objective
This study aims to examine the feasibility and acceptability of CareMOBI in the ADS setting.

Methods
A concurrent-triangulation mixed methods design was used, and participants were client-facing ADS staff members, including direct care workers (paid caregivers), nurses, and social workers. Interviews were conducted to describe barriers and facilitators to the adoption of the CareMOBI app. The acceptability of the app was measured using an adapted version of the Technology Acceptance Model questionnaire. Data were integrated into 4 themes as anchors of an informational matrix: ease of use, clinical value, fit within workflow, and likelihood of adoption.

Results
A mix of ADS staff (N=22) participated in the study. Participants reported high levels of acceptability across the 4 domains. Qualitative findings corroborated the questionnaire results; participants viewed the app as useful and were likely to implement CareMOBI in their practice. However, participants expressed a need for proper training and technical support throughout the implementation process.

Conclusions
The CareMOBI app has the potential to improve care management in the ADS setting by promoting effective communication through an easy-to-use and portable method. While the integration of CareMOBI is acceptable and feasible, developing role-specific training modules and technical assistance programs is imperative for successful implementation within the ADS setting.

OBJECTIVE
To describe the natural history of diabetes in Indians.

RESEARCH DESIGN AND METHODS
Data are from participants older than 20 years in the Centre for Cardiometabolic Risk Reduction in South Asia longitudinal study. Glycemic states were defined per American Diabetes Association criteria. Markov models were used to estimate annual transition probabilities and sojourn time through states.

RESULTS
Among 2,714 diabetes-free participants, 641 had isolated impaired fasting glucose (iIFG), and 341 had impaired glucose tolerance (IGT). The annual transition to diabetes for those with IGT was 13.9% (95% CI 12.0, 15.9) versus 8.6% (7.3, 9.8) for iIFG. In the normoglycemia ↔ iIFG → diabetes model, mean sojourn time in normoglycemia was 40.3 (34.6, 48.2) years, and sojourn time in iIFG was 9.7 (8.4, 11.4) years. For the normoglycemia ↔ IGT → diabetes model, mean sojourn time in normoglycemia was 34.5 (29.5, 40.8) years, and sojourn time in IGT was 6.1 (5.3, 7.1) years.

CONCLUSIONS
Individuals reside in normoglycemia for 35–40 years; however, progression from prediabetes to diabetes is rapid.

Published: March 2024

Introduction. When determining the number and technical equipment of fire departments, regulatory documents on fire safety do not take into account natural, climatic and geographical features of the subjects of the Russian Federation in an explicit form. At the same time, there is some information in scientific literature about the influence of certain natural and climatic factors on the effectiveness of fire protection actions in extinguishing fires. The aim of this study was to determine the influence of the system of natural, climatic and geographical characteristics of the subjects of the Russian Federation on the rapid response indicators of territorial fire departments. The results obtained are recommended for further use in rationing the number and technical equipment of fire departments.Materials and Methods. A factor analysis of statistical data for 2020–2022 was carried out. The statistical data were obtained from the Federal State Information System "Federal Database "Fires", from the website of the Federal State Statistics Service of the Russian Federation and from other sources. For the analysis, the authors selected ten indicators characterizing natural, climatic and geographical features of the subjects of the Russian Federation, two indicators of the rapid response of territorial fire departments and four indicators of the fire situation.Results. Five significant factors were identified, the change of which explained the change in the observed indicators. The first factor characterized the relationship of climatic conditions with fire situation indicators. The second factor connected the indicators of the rapid response of fire departments with the terrain features of the subjects of the Russian Federation. The third factor described the relationship between fire situation indicators and rapid response indicators with population density and forest cover of the territory. Other factors did not significantly contribute to the indicators of fire situation and rapid response.Discussion and Conclusion. By means of mathematical analysis and factor modeling, the authors investigated the interdependence of natural, climatic and geographical features of the subjects of the Russian Federation, fire situation indicators and indicators of rapid response of fire departments. The most significant factors influencing these indicators were identified. They included the average air temperature, the area covered by forest, the presence of mountain ranges, and population density. These indicators should be taken into account when determining the number and technical equipment of fire departments to increase the efficiency of their functioning.

Published: March 2024

Introduction. Intra-laboratory comparison tests play an important role in ensuring the quality and reliability of research outcomes in laboratories. These tests allow researchers to evaluate the accuracy and reproducibility of the methods they use in their work, as well as to identify potential sources of error and inconsistency. The results of these tests are shared with experts to confirm competence within the accreditation. Typically, comparison tests are carried out in laboratory conditions in a familiar and calm environment for the testers. However, when laboratories conduct research as part of a special assessment of working conditions (SAWC) they are required to conduct on-site comparisons at real-world facilities, where customers may unwittingly disrupt the process and directly affecting the quality of the measurements. The aim of this study is to evaluate the quality of on-site intra-laboratory comparison tests using the example of determining the dust content in a bricklayer's work environment on a construction site, and to determine the minimum number of measurements necessary and sufficient for this purpose.Materials and Methods. To determine the dustiness of the bricklayer's workplace, a weighing method was used. This involved collecting dust on filters and then weighing them to determine the concentration. The quality assessment of intra-laboratory tests was conducted in accordance with GOST R ISO 5725-1-2002 "Accuracy (trueness and precision) of measurement methods and results. Part 1. General principles and definitions".Results. At the bricklayer's workplace, a 1.6-fold excess of the one-time maximum permissible dust concentration was detected. The average dust concentration at the workplace under study was: Kp2 = 9.57 ± 0.81 mg/m3, the convergence of the results obtained was r = 8.68 %, the relative error δ = 8.50 %. It was revealed that the maximum allowable difference between the results of the two tests was 0.84 mg/m3. The difference in direct measurements of the mass of the two samples should be no more than 0.1 mg.Discussion and Conclusion. The results obtained demonstrated the possibility of conducting a minimum number of measurements that, under reproducible conditions, are considered satisfactory and could be provided to experts for confirming the competence of the laboratory. As part of a special assessment of working conditions, employees of the object under study are recommended to use personal respiratory protection equipment that offers protection against highly dispersed dust particles.
