NEUROTROPIC PROPERTIES OF RETROVIRUSES IN THE CONTEXT OF ANXIETY-DEPRESSIVE AND COGNITIVE DISORDERS IN HIV-POSITIVE PATIENTS

The aim: a comprehensive assessment and comparison of the prevalence of undiagnosed anxiety-depressive and cognitive symptoms in HIV-positive individuals at different stages of the disease who have been undergoing treatment for an extended period. Materials and methods According to the criteria of the scientific project, 71 HIV-positive individuals undergoing outpatient treatment with a compensated condition were involved. To explore dependencies on clinical stages (ClSt) of HIV infection and search for gender differences, the study was divided into 2 stages, respectively. The research included the collection of epidemiological and clinical-anamnestic data, as well as laboratory studies. Clinical-psychopathological and psychometric methods were used. Inclusion criteria for the study were HIV-positive status, receiving ART for more than 6 months, adulthood, and voluntary consent to participate. The obtained information was statistically processed by mathematical methods of statistics, using ANOVA criteria, Student's t-test, etc. Elements of neurocognitive and anxiety-depressive symptomatology were considered, utilizing GAD-7, HADS, and MMSE scales. Results: In patients of different groups in the first stage of the study, a gradually increasing level of anxiety and cognitive impairments was identified, depending on the stage of HIV infection. In the second stage of the study, gender and stage-related differences in anxiety and cognitive disorders were found in patients of all groups. Conclusions. Individuals in the first clinical stage (I ClSt) exhibited the least anxiety-depressive and cognitive disorders, indicating emotional and cognitive stability at this stage of HIV infection. HIV-infected individuals in the second and third clinical stages (II and III ClSt) demonstrated a progressive tendency toward anxious and depressive disorders, indicating a stage-dependent relationship to the progression of the disease. Patients in the fourth clinical stage (IV ClSt) showed the most pronounced anxious, depressive, and cognitive symptoms, which may be associated with the duration of the illness and antiretroviral therapy (ART). Research results in the female group (Group A1) suggest their lower susceptibility to disorders compared to males (Group A2) in the early stages of HIV infection. In the later stages (III-IV), it was found that women had pronounced anxious and depressive disorders (Group B1), while men exhibited signs of cognitive and depressive disorders (Group B2).

Geocell design criteria for river protection projects

The development of new ways of protecting riverbanks has evolved over time. At present, from the entire range of geosynthetics used as riverside protection works, the geocell stands out as an alternative that allows combining the established knowledge of river protections with traditional materials, to a hybrid form in which the polymer is mixed in a three-dimensional way, giving us the confinement effect, with the purpose of withstanding large deflections due to scour, high tractive resistance, and high flow velocities. For the hydraulic specialist, the lack of information on the key criteria to consider for a design with geocells for river protections, has limited their extended use. Currently there are general specifications from the Geosynthetic Institute, as well as ASTM Guides on geocells, so it is now possible to use standard or normalized Geocells for public and private works. This work presents research results and explains key concepts for the use of geocells for river protections, in order to covering the information gap in this regard. Examples of application and experiences of works already built with these criteria are presented for a complete transmission of the state of the art on this technique of geocells for hydraulic projects.

ЕКОНОМІКО-ОРГАНІЗАЦІЙНІ ПРОБЛЕМИ РОЗВИТКУ ГРОМАДСЬКОГО ТРАНСПОРТУ В УМОВАХ ВОЄННОГО СТАНУ

The modern conditions in which the cities of Ukraine find themselves dictate new conditions for the development and functioning of public transport infrastructure, which is primarily due to the challenges of martial law, threats of constant shelling by the enemy, and increased safety requirements for passengers. However, the problems of loading city transport networks have not receded into the background, but have become even more acute. Therefore, the substantiation of organizational and economic tools that will change approaches to the effective functioning and development of public transport in the conditions of martial law requires serious research. The article defines the economic importance of public transport and defines its key prospects for citizens and the entire city. Public transport is a socially important service that is usually provided or simply controlled by the state. Socio-economic indicators, which depend on the developed infrastructure of public transport, are substantiated. A model for optimizing routes and entire public transport networks is proposed. Optimal models of public transport system functioning under martial law are analyzed. The criteria of the public transport optimization project have been determined: existing transport, transport demand, the desired transport model of the city, data on passenger flows for calibration and the desired optimization criteria. Conflicting reasons for residents' choice of individual transport rather than public transport have been studied. Comfortable and profitable tools for passengers using public transport are offered. The European experience and standards of public transport infrastructure functioning of European countries are systematized. The experience of European countries shows that in order to optimize public transport routes, specialists create special transport models that reflect the current or projected future demand for transport. On the basis of the conducted research, the main directions of the development of public transport in Ukrainian cities in the conditions of martial law are proposed.

Determining design criteria for indoor positioning system projects in hospitals: A design science approach.

Indoor navigation systems (indoor positioning systems) can improve orientation for patients in hospitals and help employees to track assets. Many hospitals would like to implement indoor positioning systems but do not know how. To support them in doing this, and to gain knowledge about the requirements for indoor positioning system implementation, our research identifies the design criteria relevant to indoor positioning system implementation projects. A design science research process is built to design and evaluate an artifact. For this, five indoor positioning system developers and five hospital IT management representatives from various hospitals and companies in Germany are interviewed. Further, controlled experiments are conducted in Germany, using an ultrasound-based indoor positioning system. We determined and tested indoor positioning system functions, evaluated indoor positioning system performance criteria, and identified the operating conditions in hospitals. Our results show that indoor positioning system functions should provide a benefit to a hospital's daily operations, that some performance criteria are more important than others, and that operating conditions are important, e.g., radiation. As a theoretical contribution, we show how design science research can be applied to the context of indoor positioning systems in hospitals. In addition, we make a practical contribution in that our propositions can be used for future indoor positioning system developments.

Projective Synchronization of Discrete-Time Variable-Order Fractional Neural Networks With Time-Varying Delays.

This article is committed to studying projective synchronization and complete synchronization (CS) issues for one kind of discrete-time variable-order fractional neural networks (DVFNNs) with time-varying delays. First, two new variable-order fractional (VF) inequalities are built by relying on nabla Laplace transform and some properties of Mittag-Leffler function, which are extensions of constant-order fractional (CF) inequalities. Moreover, the VF Halanay inequality in discrete-time sense is strictly proved. Subsequently, some sufficient projective synchronization and CS criteria are derived by virtue of VF inequalities and hybrid controllers. Finally, we exploit numerical simulation examples to verify the validity of the derived results, and a practical application of the obtained results in image encryption is also discussed.

Organizational control for safety: A challenge in socioeconomic and natural environment

AbstractThe concepts and applications of cases in human factors (HFs), risk, reliability, and crisis, include the analysis of complex systems and difficult to predict sociotechnical systems. Rules and barriers are designed or revised to achieve better organizational efficiency results. The investigation then valuates the concepts such as the basis, the tests such as confirmation, the algorithms such as methods and tools, and the validation that indicates the certainty of achieving good results. The human elements (HE) are part of the design and can either disable or enable the flow of hazard energy. The intention is that these HEs inside the safety culture and technology design act as safeguards. The HE avoids design deficiencies, social and physical. HE can reduce load over the resistance capacity. The culture, social phenomenon, company project, management and staff, group and worker, operational control, failure control, and accident and disaster are classes of HF that transform hazard energy and need efficient HE barriers. The internal and external regulation after these discussions needs to revise its principles to correct processes of standardization and organizational communication, which would change the procedures for team building and the criteria for the technology project. An improvement program includes investigation of lessons learned and behavior treatment.

Multi-criteria decision support system for bridge construction system selection utilizing value engineering and TOPSIS

When selecting the appropriate bridge deck construction system, it is essential to consider many criteria such as the span length, geographical location, construction speed, cost, site conditions, resource availability, technology, ease of construction, and service life. The objective of this study is to optimize the decision-making process for selecting a bridge deck construction system in the preliminary design and planning stage. The proposed model allows designers or decision-makers to make an informed choice of an appropriate construction system according to project criteria through a decision support system. The model employs value engineering methodology and a multi-criteria decision-making method and utilizes the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS), a multi-criteria decision-making method. To gather modeling data from a focus group consisting of professional bridge engineers, a semi-structured interview and two questionnaires are conducted. When applying the proposed model to two active bridge construction projects in Egypt, it reveals that "Span by Span using launching girder" and "precast post tension girder" are better suited to cases one and two, respectively. The study makes a contribution by presenting a decision support system that combines value engineering methodology and a multi-criteria decision-making method (TOPSIS). This system empowers designers and decision-makers to make project decisions considering specific criteria and constraints.

Arithmetic Okounkov bodies and positivity of adelic Cartier divisors

In algebraic geometry, theorems of Küronya and Lozovanu characterize the ampleness and the nefness of a Cartier divisor on a projective variety in terms of the shapes of its associated Okounkov bodies. We prove the analogous result in the context of Arakelov geometry, showing that the arithmetic ampleness and nefness of an adelic R {\mathbb {R}} -Cartier divisor D ¯ \overline {D} are determined by arithmetic Okounkov bodies in the sense of Boucksom and Chen. Our main results generalize to arbitrary projective varieties criteria for the positivity of toric metrized R {\mathbb {R}} -divisors on toric varieties established by Burgos Gil, Moriwaki, Philippon and Sombra. As an application, we show that the absolute minimum of D ¯ \overline {D} coincides with the infimum of the Boucksom–Chen concave transform, and we prove a converse to the arithmetic Hilbert-Samuel theorem under mild positivity assumptions. We also establish new criteria for the existence of generic nets of small points and subvarieties.

Forecasting project success in the construction industry using adaptive neuro-fuzzy inference system

Project managers often find it a challenge to successfully manage construction projects. As a result, understanding, evaluating, and achieving project success are critical for sponsors to control projects. In practice, determining key success factors and criteria to assess the performance of construction projects and forecast the success of new projects is difficult. To address these concerns, our objective is to go beyond the efficiency-oriented project success criteria by considering both efficiency- and effectiveness-oriented measures to evaluate project success. This paper contributes to existing knowledge by identifying a holistic and multidimensional set of project success factors and criteria using a two-round Delphi technique. We developed a decision support system using the Adaptive Neuro-Fuzzy Inference System (ANFIS) to forecast the success of mid- and large-sized construction projects. We gathered data from 142 project managers in Australia and New Zealand to implement the developed ANFIS. We then validated the constructed ANFIS using the K-fold cross-validation procedure and a real case study of a large construction project in Western Australia. The forecasting accuracy measures R2=0.97461, MAPE = 2.57912%, MAE = 1.88425, RMSE = 2.3610, RRMSE = 0.03149, and PI = 0.01589 suggest that the developed ANFIS is a very good predictor of project success.

These criteria must be taken into account when choosing projects for the most effective achievement of results.

Short-Course Empiric Antibiotics in Children Undergoing Allogeneic Hematopoietic Cell Transplantation

Fever is common in children undergoing hematopoietic cell transplantation (HCT). Empiric antibiotic (EA) therapy is initiated and often continued until neutrophil engraftment. Prolonged antibiotic exposure reduces microbiome diversity and causes overgrowth of pathogenic organisms, leading to such complications as infections from antibiotic-resistant organisms and Clostridium difficile colitis. Shorter courses of EA therapy have been studied in adults undergoing HCT without significant safety concerns, but data in children are lacking. We instituted a single-center preintervention/ postintervention quality improvement (QI) project to assess the feasibility of short-course EA therapy for first fever in patients undergoing HCT. We aimed to reduce the median duration of broad-spectrum antibiotic use in eligible patients from 20 days in 2020 to 10 days in 2021. Patients were eligible for the intervention, limiting EAs to 7 days for first fever, if they were admitted for their first allogeneic HCT, were afebrile for >24 hours, had no infection requiring systemic treatment, and were hemodynamically stable. Outcome measures included days of EA therapy for first fever and total broad-spectrum antibiotic use during the period of hospitalization, defined as the time from the start of conditioning to 30 days after HCT or hospital discharge, whichever occurred first. Balancing measures included bloodstream infection (BSI), fever, and intensive care (ICU) admission within 3 days of stopping EA therapy. Project criteria were applied retrospectively to patients who underwent HCT in 2020 to construct a preintervention short-course-eligible cohort. During the intervention period, 41 patients underwent allogeneic HCT, of whom 17 (41%) were eligible for short-course EA therapy. Among eligible patients, the median age was 5.3 years, 47% had an underlying malignancy, and 88% received myeloablative conditioning. There were no differences in demographic or HCT characteristics between patients eligible for short-course EA during the intervention and preintervention period (n=24). The short-course EA schedule was adhered to by 14 of the 17 eligible patients (82%). The duration of EA for first fever and total broad-spectrum antibiotic use was significantly decreased in the short-course EA-eligible patients compared to the preintervention cohort, from a median of 17 days to 8 days and from 20 days to 10 days, respectively (P < .01). Of the 14 patients adhering to short-course EA, 2 experienced a balancing measure of recurrent fever requiring resumption of EA, but no infection was identified. There were no BSIs, ICU admissions, or deaths during the hospitalization period in patients who received short-course EA. In this single-center QI project, short-course EA for initial fever was successfully applied to children undergoing allogeneic HCT using strict criteria and led to a significant decrease in broad-spectrum antibiotic use during hospitalization. These results should be validated in a prospective clinical trial to include the impact of short-course EA on antibiotic-resistant organisms, the intestinal microbiome, and HCT outcomes.

Identification of Quantity Surveyor Competency Risk for Cost Overrun

Appropriateness of costs in the process of building a high-rise building is one of the success criteria for a construction project. However, the main problem that is often faced by most construction projects is related to the occurrence of cost overruns. Quantity Surveyor has an important role in a construction project. According to IQSI, the role of the Quantity Surveyor consists of 4 main scopes, namely planning and controlling construction costs, documenting the completeness of tender documents, contract administration, and arbitration. This study aims to identify risk factors and risk ratings from the competency of the Quantity Surveyor that have the potential to cause cost overruns. The method used in this study is the Delphi method, to validate the risks obtained from the literature study. From the results of the analysis, 52 variables with a moderate level of risk were obtained, and 3 variables with a high level of risk in the pre-construction and construction stages which could cause cost overruns.

Using the deterministic approach model for project portfolio selection problem (PPSP) solutions

Selection of projects using a robust technique is rare as most of the techniques are not considered useful due to the limitation on the number of projects that can be selected as well as cost saving projects not being selected. This study investigated the validity of a hybrid model − integrated analytical hierarchy process-goal programming (AHP-GP) − to avoid project portfolio selection problems delaying community development.The proposed model includes two steps: AHP to determine the project criteria, the relative importance of weights, and priority preferences, while the GP model was formulated to select the optimal projects. An empirical study on government agencies was carried out to validate the proposed model, and the results compared against GP as a standalone to solve the same problem. The results proved that the hybrid model (AHP-GP) was better than the GP model. AHP-GP has proved to be a robust mechanism most suitable for managerial use due to its ability to handle multi-criteria decision-making (MCDM) situations. This study showed that the hybrid model can select more projects and will create more jobs in the communities concerned compared to the single model (GP). The novelty of this study is the introduction of an integrated model formed from two distinct models as a deterministic approach to solving project portfolio selection problems.

Interdisciplinary research: Motivations and challenges for researcher careers

Abstract Interdisciplinarity is a fundamental asset in today’s research landscape, but its rules and habits vary from those of disciplinary approaches. This article aims to evaluate the impact of researchers’ participation in interdisciplinary projects on their scientific careers. To do so, we conducted a survey of researchers working at the Centre National de la Recherche Scientifique (CNRS), the largest public multidisciplinary research institution in France. The survey is based on a sample of 970 respondents, representative of scientists from all disciplines and involved to varying degrees in interdisciplinarity. The main results indicate that involvement in interdisciplinary projects often starts very early (PhD, postdoctoral), and that interdisciplinarity is not slowing down career development. Interdisciplinarity has, however, certain specificities, such as the longer duration of projects and the absence of adequate scientific journals. In terms of valorization of scientific results, differences in disciplinary uses are found. Assessment criteria for interdisciplinary projects or careers do not take sufficient account of these specificities; they are considered inadequate to the challenges of interaction between disciplines and should be rethought. We make four proposals, which we believe essential to better recognize interdisciplinary scientific engagement.

Efficacy of Interventions in Reducing the Risks of Work-Related Musculoskeletal Disorders Among Healthcare Workers: A Systematic Review and Meta-Analysis.

Work-related musculoskeletal disorders (WMSDs) are prevalent among healthcare professionals, including nurses, therapists, doctors, and paramedics, due to the potential injuries incurred during patient transfer and handling. This review aimed to assess the effectiveness of existing interventions in reducing the risks of WMSDs in this population. Four databases including PubMed/MEDLINE, Web of Science, Scopus, and ScienceDirect were searched to identify randomized and nonrandomized controlled trials, as well as studies with pre-post design. Two reviewers independently extracted data and assessed the quality of the included studies using the Effective Public Health Practice Project criteria. A meta-analysis was performed to obtain quantitative results. A total of 40 studies were included in the review. Among the interventions, motorized assistive devices showed the most significant relative reduction in WMSD risks (p < .0000; standardized mean difference [SMD] = -3.32, 95% confidence interval [CI] = [-4.53, -2.12]), followed by combined interventions of cognitive and exercise (p < .0001; SMD = -0.62, 95% CI = [-0.91, -0.33]), combined intervention of cognitive and assistive device intervention (p = .02; SMD = -0.77, 95% CI = [-1.42, -0.12]), nonmotorized assistive device (p = .02; SMD = -0.63, 95% CI = [-1.15, -0.12]), cognitive intervention (p < .0001; SMD = -0.62, 95% CI = [-0.91, -0.33]), and physical exercise (p = .06; SMD = -0.16, 95% CI = [-0.32, 0.00]) intervention. The overall evidence indicates that interventions have a significant effect in reducing the risk of WMSDs among healthcare workers, with motorized assistive devices showing the most promising results. The findings from this review can provide valuable guidance for hospital administrators, policymakers, and other experts in implementing effective strategies to prevent WMSDs among healthcare professionals.

Projective quasi-synchronization of complex-valued recurrent neural networks with proportional delay and mismatched parameters via matrix measure approach

This article is concerned with the projective quasi-synchronization of non-identical complex-valued recurrent neural networks (CVRNNs) with proportional delays and mismatched parameters. The nonlinear Lipschitz activation functions under Lyapunov stability criteria and matrix measure approach have been employed. By designing a suitable controller, a sufficient condition for projective quasi-synchronization criteria of the non-identical CVRNNs model has been derived through the proper description of the matrix measure approach. A significant result for the CVRNNs with mismatched parameters and proportional delays is provided. Finally, a numerical simulation result is given to validate the usefulness and persistence of the theoretical results. The results for different particular cases are displayed graphically.
