Published: March 2023

The article proposes the use of ideas and methods of non-standard analysis in the field of theoretical electronics. The article shows that the analysis of DC circuits, including ideal inductances and capacitances, by standard methods of theoretical electrical engineering is too complicated or almost impossible. To solve this problem, it is proposed to extend the methods of non-standard analysis by the tasks of analyzing electrical circuits with ideal reactive elements. The authors have defined a class of non-standard electrotechnical problems aimed at the analysis of DC electrical circuits, including ideal reactive elements — ideal inductances and capacitances. It is shown that the solution of the selected class of problems by standard methods of theoretical electrical engineering is too difficult or almost impossible. It is proposed to extend the methods of non-standard analysis by the tasks of analyzing electrical circuits with ideal reactive elements. The obtained advantages of this approach are confirmed by examples of calculations of electrical circuits with inductances and capacitances, as well as magnetic circuits.
Historical Themes in Fiction and Documentary Cinematography: Comparative Analysis
Authors: Kosachova O.
Published: March 2023

The purpose of this article to investigate the peculiarities of the representation of historical transformations in fiction and documentary cinematography, to reveal the artistic potential of cinema in the coverage of historical issues.

The methodology. The main methods of cognition were used: socio-communicative, axiological, culturological approaches, figurative-stylistic analysis and structural-functional method, art history approach combined with morphological analysis, hermeneutic approach. The specified methods contributed to the in-depth study of fiction and documentary films aimed at the coverage of historical or current events.

The results. In the course of the study, it was found that the line between documentary and fiction films is extremely thin, especially when the films claim to cover historical events or real figures. Despite the fact that fiction cinema is realized thanks to the play of actors, and documentary cinema is realized thanks to the shooting of real participants in the events, the means of expression of both types of cinematography are similar. One of the results of the analysis was the conclusion that documentary cinema uses a greater number of expressive means than fiction films. This is due to the fact that the directors of fiction films strive to document the aesthetics of the film, and the directors of the documentary, on the contrary, to strengthen the artistic component. Historical themes combine documentary and fiction films, while the aesthetics of documentary films is more diverse.

The scientific novelty of the research. In this research for the first time, we investigated the historical transformations in fiction and documentary cinematography from the point of view of cultural meanings and aesthetic foundations of both types of cinema, and also analyzed the potential of cinematography to reveal hot and controversial topics on the example of contemporary cinema works.

The practical significance of the article. The presented research can be used by filmmakers in both the field of fiction and documentary cinema in order to create an objective, unbiased and artistically valuable screen product. In addition, the conducted analysis can be useful in teaching professional courses in the specialty 021 “Audiovisual art and production”.

Authors: Kaletnik G. , Yaropud V.
Published: March 2023

. Air heat exchangers of the side-evaporating type based on the Maisotsenko cycle have a higher transformation coefficient, so it is advisable to use them for cooling livestock premises. However, one of the tasks of increasing the efficiency of such heat exchangers is to optimize its parameters by reducing pneumatic losses. Therefore, the aim of the research is to determine the pneumatic losses of the heat-evaporating type heat exchanger and to establish the regularity of the change of pressure and power losses required for pumping air through it from its design and technological parameters. As a result of analytical researches of pressure losses of the air heat exchanger of side-evaporating type dependences of losses of pressure and power on quantity of channels, the area of section of channels, average speed of air in channels provided their equality and their form (square, equilateral triangle, circle). It is established that the most effective form of channels in the aspect of pneumatic losses (reduction of pressure losses by 23%) have channels in the form of an equilateral triangle.

Published: March 2023

The aim of the work is to increase biogas output and generation of electricity in biogas plants due to the joint fermentation of cattle manure with winemaking waste. To achieve this goal, the following tasks were solved: the biogas yield from cattle manure with winemaking waste was determined during periodic loading of the digester; on the basis of the obtained experimental data, a mathematical model was calibrated to estimate the biogas yield during fermentation of cattle manure with the addition of winemaking waste. As a result of the studies, it was found that when manure is fermented with part of the water replaced in the substrate 2% of the winemaking waste, the fermentation dynamics in the substrate are similar to the fermentation of pure cattle manure. Biogas obtained by fermentation of manure with the addition of 2%, 6.5% and 13% of wastewater from wine production instead of water in the first day of fermentation either did not burn at all or burned poorly. The addition of winemaking waste to a substrate based on manure in an amount of 13% allows increasing the maximum biogas yield by a third to 1,372 l/(hr×kg dry organic matter). The significance of the research results lies in the fact that the use of winemaking waste as a substrate will allow a third increase in biogas output and power generation, and a reduction in the payback period of a 4,4 MW biogas plant using the green tariff to 6,5 years.
Technologicity of maintenance of combine harvesters systems during storage
Authors: Kuzmich І.
Published: March 2023

The solution of universal, global problems of energy and resource conservation in both mechanical engineering and agro-industrial complex are inextricably linked with the solution of issues of protection of machinery from corrosion.

Modern agricultural machinery, and self-propelled combine harvesters in particular, are operated periodically for one or two seasons a year. Most combine harvesters are stored in the open areas of agro-industrial enterprises, and it is exposed to aggressive environmental influences (fluctuations in temperature, humidity, wind, solar radiation, dust and others). The main type of environmental impact on the equipment is atmospheric corrosion and the corrosion wear caused by materials, parts and components, which leads to its premature failure. Thus, the fatigue strength of steel products when stored for 12 months in the open reduces by 28–58%.

To ensure temporary corrosion protection of combine harvesters, a large number of conservation and working-conservation oils are used. However, the unresolved number of issues of theoretical and practical nature leads to the unjustified use of protective equipment, which either does not provide the required duration of storage of equipment, or increase the cost of its preservation. Standardized methods of testing anti-corrosion lubricants in the vast majority have a number of disadvantages, the most important of which is that the evaluation of protective properties is carried out in units that do not allow to estimate their service life, but only show the corrosion of the metal.

OBJECTIVE

Patients with brachial plexus avulsion (BPA) experience chronic deafferentation pain characterized by two patterns: continuous background pain and electrical shooting paroxysmal attacks. The authors’ aim was to report the effectiveness and safety of dorsal root entry zone (DREZ) lesioning in relieving the two forms of pain over short and long periods.

METHODS

All patients who underwent DREZ lesioning performed by the senior author for medically refractory BPA-related pain between July 1, 2016, and June 30, 2020, in Johns Hopkins Hospital were followed up. The intensity levels for continuous and paroxysmal pains were evaluated using the numeric rating scale (NRS) preoperatively and at 4 time points postsurgery, including the day of discharge, with a mean hospital stay of 5.6 ± 1.8 days; first postoperative clinic visit (33.0 ± 15.7 days); short-term follow-up (4.0 ± 1.4 months); and long-term follow-up (3.1 ± 1.3 years). The percent of pain relief according to the NRS was categorized into excellent (≥ 75%), fair (25%–74%), and poor (< 25%).

RESULTS

A total of 19 patients were included, with 4 (21.1%) lost to long-term follow-up. The mean age was 52.7 ± 13.6 years; 16 (84.2%) were men, and 10 (52.6%) had left-sided injuries. A motor vehicle accident was the most common etiology of BPA (n = 16, 84.2%). Preoperatively, all patients had motor deficits, and 8 (42.1%) experienced somatosensory deficits. The greatest pain relief was observed at the first postoperative and short-term follow-up visits, with the lowest proportions of patients having continuous pain (26.3% and 23.5%, respectively) and paroxysmal pain (5.3% and 5.9%, respectively). Also, the highest reductions in mean NRS scores were observed for first postoperative and short-term follow-up visits (continuous 1.1 ± 2.1 and 1.1 ± 2.3; paroxysms 0.4 ± 1.4 and 0.5 ± 1.7, respectively) compared to the preoperative symptomatology (continuous 6.7 ± 3.0; paroxysms 7.9 ± 4.3) (p < 0.001). Most patients had excellent relief of continuous pain (82.4% and 81.3%) and of paroxysms (90.9% and 90.0%) at the first postoperative visit and short-term follow-up visit, respectively. The pain relief benefits had diminished by 3 years after surgery but remained significantly better than in the preoperative assessment. At the last evaluation, the proportion of patients achieving excellent relief of paroxysmal pain (66.7%) was double that for continuous pain (35.7%) (p < 0.001). New sensory phenomena were observed among 10 patients (52.6%), and 1 patient developed a motor deficit.

CONCLUSIONS

DREZ lesioning is an effective and safe option for relieving BPA-associated pain, with good long-term outcomes and better benefits for paroxysmal pain than for the continuous pain component.

Published: March 2023

OBJECTIVE

Infuse bone graft is a widely used osteoinductive adjuvant; however, the simple collagen sponge scaffold used in the implant has minimal inherent osteoinductive properties and poorly controls the delivery of the adsorbed recombinant human bone morphogenetic protein–2 (rhBMP-2). In this study, the authors sought to create a novel bone graft substitute material that overcomes the limitations of Infuse and compare the ability of this material with that of Infuse to facilitate union following spine surgery in a clinically translatable rat model of spinal fusion.

METHODS

The authors created a polydopamine (PDA)–infused, porous, homogeneously dispersed solid mixture of extracellular matrix and calcium phosphates (BioMim-PDA) and then compared the efficacy of this material directly with Infuse in the setting of different concentrations of rhBMP-2 using a rat model of spinal fusion. Sixty male Sprague Dawley rats were randomly assigned to each of six equal groups: 1) collagen + 0.2 µg rhBMP-2/side, 2) BioMim-PDA + 0.2 µg rhBMP-2/side, 3) collagen + 2.0 µg rhBMP-2/side, 4) BioMim-PDA + 2.0 μg rhBMP-2/side, 5) collagen + 20 µg rhBMP-2/side, and 6) BioMim-PDA + 20 µg rhBMP-2/side. All animals underwent posterolateral intertransverse process fusion at L4–5 using the assigned bone graft. Animals were euthanized 8 weeks postoperatively, and their lumbar spines were analyzed via microcomputed tomography (µCT) and histology. Spinal fusion was defined as continuous bridging bone bilaterally across the fusion site evaluated via µCT.

RESULTS

The fusion rate was 100% in all groups except group 1 (70%) and group 4 (90%). Use of BioMim-PDA with 0.2 µg rhBMP-2 led to significantly greater results for bone volume (BV), percentage BV, and trabecular number, as well as significantly smaller trabecular separation, compared with the use of the collagen sponge with 2.0 µg rhBMP-2. The same results were observed when the use of BioMim-PDA with 2.0 µg rhBMP-2 was compared with the use of the collagen sponge with 20 µg rhBMP-2.

CONCLUSIONS

Implantation of rhBMP-2–adsorbed BioMim-PDA scaffolds resulted in BV and bone quality superior to that afforded by treatment with rhBMP-2 concentrations 10-fold higher implanted on a conventional collagen sponge. Using BioMim-PDA (vs a collagen sponge) for rhBMP-2 delivery could significantly lower the amount of rhBMP-2 required for successful bone grafting clinically, improving device safety and decreasing costs.

Published: March 2023

OBJECTIVE

The authors aimed to determine the poor prognostic factors of balloon kyphoplasty for the treatment of fractures of the most distal or distal-adjacent vertebrae in ankylosing spines with diffuse idiopathic skeletal hyperostosis (DISH).

METHODS

Eighty-nine patients with fractures of the most distal or distal-adjacent vertebrae of ankylosing spines with DISH were included and divided into two groups: those with (n = 51) and without (n = 38) bone healing 6 months postoperatively. Clinical evaluation included age, sex, time from onset to surgery, the visual analog scale score for low-back pain, and the Oswestry Disability Index (ODI). The VAS scores and ODI were measured both preoperatively and at 6 months postoperatively. Radiological evaluations included bone density; wedge angles of the fractured vertebrae in the supine and sitting positions on lateral radiographs; differences in the wedge angles (change in wedge angle); and the amount of polymethylmethacrylate used.

RESULTS

The preoperative ODI, vertebral wedge angles in the supine and sitting positions, change in wedge angle, and amount of polymethylmethacrylate were significantly different between the two groups and were significantly associated with delayed bone healing in univariate logistic regression analysis. Multivariate logistic regression analysis showed that only a change in the wedge angle was significantly associated with delayed healing, with a cutoff value of 10°, sensitivity of 84.2%, and specificity of 82.4%.

CONCLUSIONS

Treatment with balloon kyphoplasty alone should be avoided in patients with a difference ≥ 10° in the wedge angle of the fractured vertebrae between the supine and sitting positions.

Published: March 2023

According to the results of the Indonesia Nutrition Status Study (SSGI) in 2021, as many as 20.8% Baduta and 24.4% Toddlers were stunted/short. In addition to fulfilling nutrition for children, the immunization sector also shows the same thing. During the last 2 years from 2020-2021 the coverage of complete basic immunization for infants has fallen drastically. Researchers developed this application using the SDLC Waterfall model. The waterfall method has the advantage that when all systems can be fully and correctly defined at the beginning of the project, software engineering can run well without any problems. The data collection technique used was secondary data that had been previously collected by other parties using the internet, library research, and books related to research. The Child Health Record application is expected to be an application that can help parents control their children's health from an early age. The immunization feature in the application is expected to increase complete basic immunization coverage for children, increase parental awareness in fulfilling child nutrition, increase parental awareness of children's nutritional status and explore information related to knowledge about children's health. The use of the Child Health Record application can be used since children are 0 years old so that the monitoring process runs optimally. Application development can be developed into a personal health record that can be used as an adult or a family health record.

Effect of Phytoremediation of Eichornia crassipes (Mart.) Solms and Marsilea crenata C. Persl on Reduction of Phosphate Levels in Laundry Waste
Authors: Vatmawati V.N. , Rachmadiarti F.
Published: March 2023

Detergent serves as the most widely used cleaner, one of the ingredients for detergent is phosphate. Excessive phosphate in the waters will cause eutrophication and endanger the aquatic biota in it. Therefore, a solution is needed to reduce phosphate in the waters; one such way is by using Eichornia crassipes (Mart.) Solms and Marsilea crenata C. Presl. The purpose of this study was to determine the effect of plant species and phytoremediation time on phosphate levels in laundry waste. The variables studied were variations in plant species and phytoremediation time. In the plant variety, water hyacinth, water clover, and a combination of the two are used. In the variation of time used 0, 48 and 96 hours. The waste used is waste from a laundry business in Wonokromo, Surabaya. Parameters tested include phosphate, DO, BOD, pH, temperature, and turbidity. The exploration stage is in the form of acclimatisation and range finding tests to determine the concentration of wastewater used in the experimental stage. The results showed that plant species and phytoremediation time affected the decrease in phosphate levels. The correlation between phytoremediation time on parameters of phosphate levels, BOD, and pH will decrease with the duration of phytoremediation, but DO parameters will increase with the duration of phytoremediation.
Optimisation of Reverse-Osmosis Water Purification Plant Powered by Hydro-Generators at the Dead Sea
Authors: Marar Hazem W.
Published: March 2023

With the Jordan River as its main tributary, the Dead Sea is a hyper-saline lake, which was formed around 140 centuries ago. Climate change used to be the principal driver of water level changes. However, anthropogenic activities have recently emerged as a prominent source of excessive depletion. This study provides a realistic strategy for desalinating the Red Sea water whilst generating electrical power for the Dead Sea conveyance project. Seawater from the Gulf of Aqaba is transformed into highly concentrated saline water flowing to the Dead Sea whilst delivering purified drinking water to nearby regions using reverse osmosis plants. Being an energy-intensive process, a series of hydro-generators with efficient energy recovery devices will minimise the running cost by half.

Studies on ambient PM2.5 exposure and AURI and ALRI in regions such as South and South-East Asia, where levels of PM2.5 are among the highest, are limited. We assessed the associations between ambient PM2.5 exposure and AURI and ALRI in children under the age of 5 years from South and Southeast Asia. We identified subjects from the demographic health survey (DHS). We retrieved PM2.5 information from the Atmospheric Compositional Analysis Group. Annual mean levels of PM2.5 ranged from 21.3 to 73.2 μg/m3. We performed the meta-analytical approach to obtain the pooled results. Our initial results show an association between ambient PM2.5 exposure and AURI (OR 1.06, 95% CI: 1.01-1.11) but not ALRI (OR 1.03, 95% CI: 0.98-1.09). However, after controlling for indoor SHS, effect estimates became stronger for AURI and ALRI (OR 1.27, 95% CI: 1.04-1.54 and OR 1.20, 95% CI: 1.00-1.44) compared to the uncontrolled group. Our study shows an association between ambient PM2.5 exposure and the prevalence of AURI and ALRI in children under the age of 5 years from South and Southeast Asia. Promoting awareness of air pollution in line with the implementation and monitoring of relevant policies is crucial in establishing clean air and health.

In the absence of environmental regulation, food stays to be contaminated with heavy metals, which is becoming a big worry for human health. The present research focusses on the environmental and health effects of irrigating a number of crops grown in the soils surrounding the Al-Rustamia old plant using treated wastewater generated by the plant. The physicochemical properties, alkalinity, and electrical conductivity of the samples were evaluated, and vegetable samples were tested for Cd, Pb, Ni, and Zn, levels, and even the transfer factor (TF) from soils to crops and crop and multi-targeted risk, daily intake (DIM) of metals, and health risk index (HRI) was calculated. The findings found that the average contents of Zn, Pb, Ni, and Cd in soil and vegetation were less than the Food and Agriculture Organization’s standards of food safety enhancers. The flooded soil included Zn (56.5), Pb (15.1), Ni (9.30), and Cd (0.850) mg·kg-1. The heavy-metal concentration trend in all samples was Zn, Pb, Ni, and Cd. Daily metal intake in crops species was above acceptable limits for Zinc (0.011 – 0.019 mg·kg-1), Lead (2.010-5 – 5.910-5 mg·kg-1), Ni (2.410-4 – 5.210-4 mg·kg-1) and Cd (1.310-5 – 3.310-5 mgkg-1). The HRI for zinc varied between 0.037 and 0.063, for lead between 5.10-3 and 1.410-2, for nickel from 1.210-2 to 2.610-2, and for cadmium from 1.310-2 to 3.310-2. The HRI for such components was larger than one, suggesting that no possible health issue existed. Crop cultivation using wastewater is a typical solution for water-stressed nations; nevertheless, previous screening and processing of such industrial wastewaters is required to minimise its detrimental effects on the environment.

Published: March 2023

Mediterranean Rivers are often increasingly subjected to stress as a result of riparian population activities. This present study assessed the impact of human activities on the water quality of the Inaouene River in Morocco. For this purpose, water samples were collected from seven sampling stations along the River and analysed. The water of the Inaouene River is characterised by slightly alkaline water pH (7.32-7.59), electrical conductivity (1206.44-3674.14 μS cm-1), very low level of dissolved oxygen (1.98-5.55 mg L-1), BOD5 (45.42-328.7 mg L-1), COD (112.71-468.46 mg L-1). The results classify the Inaouene River’s water in the “moderate to poor” quality range based on Moroccan standards. This water, which is characterised by moderate to severe organic contamination, is also distinguished by a significant allochthone charge from the different riparian urban centres. The multivariate analysis showed a decline in water quality and high amounts of organic matter, nitrogenous and phosphorus in urban centres downstream. Waters from stations located further away from domestic discharge points are less polluted and more oxygenated. Overall, these findings confirmed that the combined effect of anthropogenic activities and the seasonality characteristic of the Inaouene watershed is the main factor that determines water quality.
Digital Transformation of Inland Terminals

Published: March 2023

Small and medium-sized (SME) logistics hubs are characterized by a variety of customer relationships, different services offered, and diverse organizational interfaces. Increased requirements for workflows that run smoothly, at best digitally, are often met by using individual IT systems at hubs like inland intermodal terminals. In this context, the development and introduction of systems are rarely characterized by a uniform strategy, but by short-term requirements and interim solutions. This paper aims to develop an IT reference model for SME inland terminals. The focus is on supporting the independent and structured further development of processes and IT landscapes by the terminals. The paper is based on a project, which was carried out in exchange with experts and involved parties as well as based on a literature analysis to highlight SME- and branch-specific issues. Modeling the current situation creates a basis for identifying weaknesses and target landscapes. Reference process models assist with the systematic mapping and analysis of IT and process landscapes and hold opportunities to identify potentials to increase productivity, reduce costs and avoid redundancies. It consists of many process models, tools, and recommendations for action, which together comprise a “help for self-help” approach. Implications for making process models more flexible to respond to external demands were considered.

Feature Selection (FS) for Sentiment Analysis (SA) becomes a complex problem because of the large-sized learning datasets. However, to reduce the data dimensionality, researchers have focused on FS using swarm intelligence approaches that reflect the best classification performance. Crocodiles Hunting Strategy (CHS), a novel swarm-based meta-heuristic that simulates the crocodiles’ hunting behaviour, has demonstrated excellent optimization results. Hence, in this work, two FS algorithms, i.e., Binary CHS (BCHS) and Improved BCHS (IBCHS) based on original CHS were applied for FS in the SA field. In IBCHS, the opposition-based learning technique is applied in the initialization and displacement phases to enhance the search space exploration ability of the IBCHS. The two proposed approaches were evaluated using six well-known corpora in the SA area (Semeval-2016, Semeval-2017, Sanders, Stanford, PMD, and MRD). The obtained result showed that IBCHS outperformed BCHS regarding search capability and convergence speed. The comparison results of IBCHS to several recent state-of-the-art approaches show that IBCHS surpassed other approaches in almost all used corpora. The comprehensive results reveal that the use of OBL in BCHS greatly impacts the performance of BCHS by enhancing the diversity of the population and the exploitation ability, which improves the convergence of the IBCHS.

A system undergoes a failure process in which the internal degradation and external loads are independent and compete with each other. In the reliability model of competitive failure, the threshold of failure is often a dynamic process that changes with time. Based on this, this paper constructs a model in which the failure threshold is an uncertain Liu process and applies it to the competitive failure reliability process, where soft and hard failure thresholds are modeled by different Liu processes. In the absence of a large amount of failure data, uncertainty theory is used as a tool to analyze the belief reliability and mean time to failure of the system. Taking gas-insulated substation (GIS) as an example, the effect of parameters on belief reliability is analyzed, and the reliability under Liu process threshold and constants threshold is compared, which shows the validity of the prosed model.
T2-fuzzy multi-fused facial image fusion (T2FMFImgF): An efficient face recognition

Published: March 2023

This paper presents a novel decision-making method for face recognition where the features were extracted from the original image fused with its corresponding true and partial diagonal images. To extract features, we adopted the generalized two-dimensional FLD (G2DFLD) feature extraction technique. The feature vectors from a test image are given as input to neural network-based classifier. It is trained with the feature vectors of original image and diagonally fused images and thereby the merit weights with respect to different classes were generated. To address the factors that affect the face recognition accuracy and uncertainty related to raw biometric data, a fuzzy score for each of the classes is generated by treating a type-2 fuzzy set. This type-2 fuzzy set is formed by the feature vectors of both the diagonally fused training samples and the test image of the respective classes. A concluding score for each of the classes under consideration is computed by fusing complemented merit weight with the complemented fuzzy score. These class-wise concluding scores are considered in the face recognition process. In this study, the well-known face databases (AT&T, UMIST and CMU-PIE) are used to evaluate the performance of the proposed method. The experimental results illustrate the fact that the proposed method has exhibited superior classification precision as compared with other state-of-art methods. Our T2FMFImgF method achieves highest face recognition accuracies of 99.41%, 98.36% and 89.80% in case of AT&T, UMIST and CMU-PIE (with expression), respectively while for CMU-PIE (with Light) the highest recognition accuracy is 97.957%. In addition to it, the presented method is quite successful in fusing and classifying textural information from the original and partial diagonal images by integrating them with type-2 fuzzy set-based treatment.
Research on endogenous internet public opinion dissemination in Chinese universities based on SNIDR model
Authors: Qu Ying , Chen Hong
Published: March 2023

During an emergency, the negative Internet public opinion in colleges and universities, especially the negative endogenous public opinion, will have a serious impact on the reputation of colleges and universities. It is of great significance to find out the negative influencing factors of endogenous public opinion and explore the mechanism of public opinion dissemination for resolving the crisis of public opinion in universities. The existing research does not distinguish the endogenous Internet public opinion in colleges and universities from the general Internet public opinion in colleges and universities, and the SIR model adopted fails to fully reflect the difference between students and other dissemination subjects of endogenous public opinion in campus. In addition, various research methods and models currently used focus on the static expression of dissemination results, and the explanation of results is insufficient. The reason is that they do not well express the dynamic interaction mechanism between influencing factors and the dynamic conversion rate between roles. In this study, based on the improved infectious disease model and system dynamics theory, AnyLogic software is used to simulate the improved SNIDR model of infectious disease, to analyze the sensitivity of school supervision, school intervention, school response time and information transparency and to study the dynamic conversion rate between different roles. The SNIDR model effectively simulates the process of endogenous public opinion dissemination in colleges and universities after emergencies. The results show that, what has the greatest impact on the dissemination of public opinion is the school’s supervision and intervention efforts, which can suppress the dissemination from the source. Information transparency is an auxiliary variable and cannot function independently. During the dissemination period, the timelier the school responds, the faster the spreaders will drop to zero, and the better it will be to control the secondary dissemination of public opinion.

Published: March 2023

The present study considers non-mixture models based on the discrete Burr XIII distribution to model recurrent event data in the presence of a cure fraction. In this context, we provide an alternative to the standard Cox proportional hazards model using a discretized distribution to analyze lifetime data assuming a non-mixture structure for cure rates. In a Bayesian setting, the proposed methodology was considered for analyzing a real dataset from a retrospective cohort study that aimed to evaluate specific clinical conditions that affect the lifetimes of 299 heart failure patients admitted to the Institute of Cardiology and Allied Hospital – Faisalabad, Pakistan (April-December, 2015). The model validation process was addressed using the Cox-Snell residuals, which allowed us to identify the suitability of the proposed non-mixture cure rate model.
How good is the diagnostic test accuracy of telehealth assessment for dementia and mild cognitive impairment? A Cochrane Review summary with commentary
Authors: Ferrario Irene
Published: March 2023

BACKGROUND: It is estimated that 50% to 80% of people living with dementia worldwide remain undiagnosed and undocumented and have no access to care and treatment. Telehealth services can be utilized as one of the options to improve access to a diagnosis, especially for people living in rural areas or affected by COVID-19 containment measures. OBJECTIVE: To assess the diagnostic accuracy of telehealth assessment for dementia and mild cognitive impairment (MCI). METHODS: A summary of the Cochrane Review by McCleery et al. 2021, with comments from a rehabilitation perspective. RESULTS: Three cross-sectional diagnostic test accuracy studies (N = 136) were included. Participants were referred from primary care when presenting with cognitive symptoms or were identified as being at high risk of having dementia on a screening test in the care homes. The studies found that telehealth assessment correctly identified 80% to 100% of the people who were diagnosed with dementia during face-to-face assessment and also correctly identified 80% to 100% of people who did not have dementia. Only one study (N = 100) focused on MCI; 71% of participants who had MCI and 73% of participants who did not have MCI were correctly identified via telehealth assessment. Telehealth assessment in this study correctly identified 97% of the participants who had either MCI or dementia, but correctly identified only 22% of those who did not have either. CONCLUSION: Telehealth assessment for diagnosing dementia seems to have a good level of accuracy when compared to face-to-face assessment, although the small number of studies and small sample sizes and differences between the included studies indicate that the results are uncertain.
PROPERTY LIFE CYCLE COST ANALYSIS METODS
Authors: Drapikovskyi Oleksandr , Іvanova Iryna
Published: March 2023

The minimization of the property life cycle cost as a criterion for making a decision regarding the economic feasibility of purchasing or building a certain real estate object compared to other objects with functional utility today has become a mandatory requirement of most regulatory and legal acts in Ukraine.

At the same time, the practical implementation of this requirement faces the problem of methodical provision of life cycle cost analysis from the standpoint of the uncertainty of these costs in the future and the need to take into account the time value of money.

The application of valuation procedures based on cash flow discounting, proposed in this article, can contribute to the solution of this problem.

Discounting cash flows will require the classification of life cycle costs not only by content load, but also by the time of their occurrence into initial and future costs, which in turn are divided into once-only, periodic and regular costs.

Acceptable units of measurement of discounted cash flows can be net present costs, equivalent annual cost, net savings; savings to investments ratio, internal rate of return, discounted payback period, each of which corresponds to its own model and valuation criterion.

To solve the problem of the uncertainty of future costs and to take into account the risk inherent in their forecasting, the methods of analyzing the sensitivity of the results to changes in the market situation are proposed and the justified feasibility of using stochastic discounted cash flows models is justified.

Published: March 2023

The article highlights the analysis of approaches to formulating the concept of "development". Also, the main features were determined, and their regulatory and legal basis was investigated. The article outlines the problems of development projects in the form of public-private partnerships and ways to solve them.

Development as a form of public-private partnership has a long history, but the study of this phenomenon has become most relevant in recent decades.

The study of the development, its legal basis, problems, methods of solving them, and their main characteristics is now a priority task since the political, economic, legal, and social positions of bodies are being formed to achieve cooperation, to implement programs of social and economic development, investment and infrastructure projects.

Implemented state-legal partnership projects yield positive results. It is this experience that the state authorities can use to solve many problems of the economic complex in order to increase the level and efficiency of service provision.
