Published: May 2022

The article deals with the issues of vehicle traffic safety on artificial constructions. Ensuring safety in the field of rail transport is an essential element in the activities of all subjects of the market of railway services, including passenger carriers. To fully study the issues of the deformed state of beam superstructures, it is necessary to conduct static and dynamic tests. Before the start of the tests, it is mandatory to check the technical condition of the artificial structure:
1) visual inspection, special checks with verification of necessary parameters;
2) carrying out control linear measurements;
3) selective determination of concrete strength by non-destructive methods.
First, the static tests is conducted to determine the total deformations of each beam of the superstructure at the control point with maximum deformations of ½ L. Then dynamic tests with determination of periods of natural oscillations and deformations (stresses). Processing of the results of surveys and tests of the overpass with an assessment of the possibility of passing design loads on the road bridge, after which a dynamic passport of the transport structure is compiled. The study of the stressed state of vehicles gives a clear idea of the causes of deformations in the structural elements when analyzing the work of the span of the automobile bridge in conditions of increasing axial loads and traffic flow speeds. Deformation processes lead to defects, structural failures and accidents on the vehicle, which leads to premature wear, material damage and environmental damage. Periodic measurements of deformations (stresses) of the superstructure structure over several years will make it possible to predict changes in its condition over time and determine the remaining resource in terms of load-bearing capacity and load capacity. As a result of experimental studies, it was proved that the presented technique, developed in the classical version for detecting structural defects between a single-layer coating and a base of various types, can also work effectively in the case of non-destructive testing of multilayer structures

Published: May 2022

As an additive to bread, it is proposed to use a powder made from derivatives of Sorbus aucuparia mountain ash processing. The powder production technology involves freezing fruits, preliminary dehydration by osmotic dehydration, drying in an infrared dryer and grinding. The technology of bread with an extended shelf life and increased biological value has been developed, and some of its physical and chemical properties have been studied. To determine the feasibility of using powders from Sorbus aucuparia processing derivatives, their amino acid spectrum was analyzed by the chromatographic method. 17 amino acids in the amount of 7.43 g/100 g were identified, 7 of which are essential (valine, leucine, isoleucine, lysine, methionine, threonine, phenylalanine) in the amount of 1.84 g/100 g. The highest concentration of the total number of amino acids is glutamic acid (1.57 g/100 g), which gives the powders the properties of natural preservatives, increases the storage capacity of bread. The experiment showed that adding 20 % powder from Sorbus aucuparia processing derivatives to wheat flour bread allows at least doubling its shelf life. However, such an amount of additive affects the porosity of the bread and its organoleptic properties. Therefore, a sample was made with the addition of 10 % powder, and no defects in taste, smell and shape of bread with the addition of mountain ash powder were found. When using the developed technology, the time for making bread is reduced by 30 minutes compared to the classic straight dough method and by 120–150 minutes compared to the sponge dough method. The shelf life of bread according to the proposed technology is 15 days

Published: May 2022

This paper considers the influence exerted on the qualitative indicators of boiled camel sausage by plant-based additives. The study’s results were used to improve the technology and determine the levels of application of plant-derived extracts with antioxidant properties in the production of boiled sausages. The effect of plant extracts with antioxidant properties on oxidative processes in boiled sausages has been investigated. Camel meat contains phosphorus, magnesium, and potassium. This meat has a large content of vitamins A, B1, B2, C, and E. In terms of protein content (15.1 %), camel is inferior to beef; in terms of fat (11.5 %), it is inferior to other types of meat. However, camel meat is rich in vitamins and trace elements. In addition, the composition of camel meat contains phosphorus, 216‒234 mg, which is higher than that of beef.
The disadvantage of boiled camel sausages is a short shelf life. Therefore, it was decided to add plant-based supplements with antioxidant properties. In addition, to ensure minimal lipolytic changes and changes in lipid oxidation in meat, the rational concentration of added antioxidants was determined. Using the response surface methodology, a three-level factor plan was constructed for two variables – the concentration of ginger root powder and sea buckthorn powder. The minimum acid number was manifested at 0.018 % of ginger root powder and 0.035 % of sea buckthorn powder. The minimum peroxide number was obtained at 0.028 % of the L-root of ginger and 0.010 % of the powder of sea buckthorn; the minimum TBARS was detected at 0.030 % of the powder of ginger root and 0.050 % of the powder of sea buckthorn. The concentration of ginger root powder with optimal resistance to oxidation and lipolysis is proposed. The shelf life was also determined in comparison with the control

Published: May 2022

Comparison of thorium nitride (ThN) and uranium nitride (UN) fuel on small modular PWR in neutronic analysis has been carried out. PWR in module is one type of reactor that can be utilized because of its small size so that it can be placed on demand. Neutronic calculations were performed using SRAC version 2006, the data library using JENDL 4.0. The first calculation was fuel pin (PIJ) calculation with hexagonal fuel pin cell type. And the second calculation was reactor core (CITATION) calculation using homogeneous and heterogeneous core configurations. ThN and UN fuels use heterogeneous configurations with 3 fuel variations. The reactor geometry was used in two fuels are the same, with diameter and height active core was 300 cm and 100 cm. In this research, Np-237 was added as a minor actinide in the UN fuel to reduce the amount of Np-237 in the world and also reduce the k-eff value. For ThN fuel, Pa-231 also added in the fuel to reduce the k-eff value. The optimum configuration of UN fuel reached when used heterogeneous core configuration case four with percentage of U-235 in F1=5.5 %, F2=7 % and F3=8.5 % also with the addition of Np-237 0.2 % and fuel fraction 56 %. It has a maximum excess reactivity value 12.56 % %∆k/k. And then, the optimum configuration of ThN fuel reached when used heterogeneous core configuration case three with percentage of U-233 in F1=2 %, F2=4 % and F3=6 % with the addition of Pa-231 0.5 % and fuel fraction 53 %. It has a maximum excess reactivity value 7.67 % %∆k/k. The comparison of optimum design of UN and ThN fuel shows that the ThN fuel has the k-eff value closer to critical than UN fuel. Therefore, in this study, ThN fuel is more suitable for use in PWR reactors because it has a small excess value and can operate for 10 years without refueling

Logistic system of metformin scientific research allows: to demonstrate the uniqueness of the drug, to reveal its potential and new opportunities for medical use, prospects for the development of new types of dosage forms and new combined drugs; to identify the threat of patent infringement, to identify opportunities for establishing partnerships; to present scientific products in the form of a drug on the pharmaceutical market, optimizing the research time, reducing the development stages due to the available information and documentation, ensuring the synchronization of innovative information flows; to optimize the total costs of scientific research and receive at the expense of the specified profit.
Logistic system of metformin scientific research is recommended for implementation in scientific organizations and pharmaceutical companies that perform R&D to achieve concentration of information search in solving logistics problems in the field of creating medicines based on metformin.
Conclusions. Thus, the management of scientific research in pharmacy using the logistic approach ensures the time reduction of the medicine to entry into the market, reduces the cost of its creation, prevents duplication of research, and promotes optimization of solutions. The analysis revealed that the creation of medicines based on metformin should be aimed at the search and development of combined sugar-reducing drugs with mutually complementary mechanisms of action
Features of microsporidia Nosema apis and Nosema ceranae (Nosema species) development of winter bee (Apis mellifera L.) generation
Authors: Odnosum Hanna , Yefimenko Tetiana
Published: May 2022

Temperature is one of the main abiotic factors affecting the development of causative agents of nosemosis in the bee's body.

The aim of the research. To determine the influence of the winter and summer bee nest temperature (20–22 °C and 35–36 °C, respectively) on the duration of Nosema species development of winter bee generation isolated in hoarding cages, and to trace the life cycle of Nosema species of bees with natural infection and overwintering in natural conditions, from November to the beginning of bee brood rearing (February).

Materials and methods. For this, 200 bees Apis mellifera sossimai, selected from bee colony in November, were infected by syrup feeding containing Nosema species (5×104 spores per bee). Half of the bees were kept at 35–36 °C and half at 20–22 °C. The stages of Nosema species development were monitored daily for 13 days in midgut smears, stained according to Romanovsky-Giemsa (magnification 900x). Furthermore, with a 15 days frequency, from November to mid-February, 30 bees were selected from 20 bee colonies overwintered in natural conditions, and monitored the stages of Nosema species development at natural infection.

Result. It was found that the Nosema species development of winter bee generation artificially infected by Nosema species, was suspended at meronts and sporonts stages until the 13th day from the moment of infection, regardless of the temperature at which the bees were kept in the experiment. In bees selected from bee colonies naturally infected with Nosema species prevailed meronts I, II and in an insignificant amount sporonts, until the end of December, active sporulation took place from the middle of January to the beginning of February.

Conclusion. That is, the duration of the life cycle development of Nosema species depends little on temperature but is closely related to the life span of summer and winter bee generation and determined by the biochemistry of their relationships, which allow the parasite to save the host as its habitat
Maize Lethal Necrosis: Impact and Disease Management
Authors: Ohlson Erik W. , Wilson Jennifer R.
Published: May 2022

The authors summarise and explore maize lethal necrosis (MLN) global impact, its causal viruses, their vectors, and disease management strategies. MLN is a destructive synergistic virus disease of maize caused by maize chlorotic mottle virus (MCMV) in combination with one of several
viruses in the Potyviridae family. MLN causes severe chlorosis, necrosis, and eventual plant death, instigating severe yield losses. The causal viruses of MLN are mostly transmitted between plants by arthropod vectors, but they can also be transmitted at low frequency through seed and soil.
Effective MLN management approaches include developing and growing maize with improved tolerance, crop rotation, controlling arthropod vector populations, managing disease reservoirs, and reducing disease transmission and spread through seed and soil. Despite the devastating impact of MLN
over the past decade, especially in East Africa, tremendous progress has been achieved towards successful disease management. The rapid development and deployment of MLN tolerant maize in East Africa has proven an extremely effective management strategy, despite continuous maize plantings
and the extensive presence of "green bridges". Identifying and stacking additional sources of MLN tolerance is desirable for breeding durable resistance. In the U.S., weed and vector management combined with crop rotation has effectively prevented the spread of MLN beyond a few states in the
Midwest. However, it is important to consider the potential impact of climate change and the presence of pesticide/Bt resistant MLN insect vectors, which may facilitate greater vector proliferation and virus spread. Continued vigilance geared towards preventing virus or vector introduction
to new locations is desirable, especially in tropical climates where multiple growing seasons occur annually. Fortunately, conditions conducive to an MLN epidemic are complex, requiring the presence of multiple maize infecting viruses and their respective vectors. Thus, several combinations
of the disease management strategies discussed above are effective at managing the disease.
Coronavirus infection COVID-19 in children: a literature review
Authors: Dolgopolov I. S. , Rykov M. Yu.
Published: May 2022

Introduction. In late 2019, a new subtype of coronavirus named severe acute respiratory syndrome-related coronavirus 2 (SARS-CoV-2) rapidly spread around the world, causing a global pandemic. Initially, the proportion of confirmed cases among children was relatively small, and it was believed that children were rarely infected. Subsequent observations have shown that in children and adolescents, the infection is either asymptomatic or accompanied by minimal clinical symptoms, and therefore the true incidence is under-estimated due to the low level of testing.

Aim. To summarize and systematize the results of studies on the prevalence, diagnosis, clinical picture, vaccination and treatment of children with a new coronavirus infection COVID-19.

Materials and methods. PubMed searched articles published up to January 15, 2022 using combinations of the following words: COVID-19, SARS-CoV-2, children, pediatrics, adolescents, infants, and school. We read the abstracts of 101 articles and selected 78 articles based on their relevance to the topics discussed. We also analyzed 3 articles on vaccination of children. A total of 89 articles were included in the review.

Results. The SARS-CoV-2 positivity rate throughout the peak of the pandemic in children was low compared to adults, including those who had an acute respiratory infection. Children are not only less likely to become infected with the virus, but they also carry the infection more easily than adults. The mortality rate in children with COVID-19 was < 0.5%. In most children, infection is either asymptomatic or accompanied by an erased clinical picture. Vaccination of children and adolescents is recommended mainly to achieve herd immunity in all age groups. However, there are no convincing data on the duration of the immune response, the level of the required protective antibody titer, as well as on the long-term side effects of vaccination due to the insufficient follow-up period and the uncertainty of the immune response criteria.

Conclusion. As information is accumulated on the viral load of children and adolescents, their role in the transmission of the virus, diagnostic approaches in this age group are optimized. The effectiveness of the treatment was tested on patients admitted to the hospital, and recommendations for treatment were developed. Currently, global research efforts are focused on the protection of especially vulnerable children, the prospects for total childhood vaccination, its effectiveness and safety.

Toward a Restorative Math Pedagogy: A Theoretical Overlay Between Two Relational Approaches to Schooling and Mathematics Instruction
Authors: McQueen Shanté
Published: May 2022

Emphasized by the fallout of the pandemic, critical math scholars have long-since called for resistance to the cultural marginalization, systemic racism and violence of math instruction by crafting a liberatory and humanizing mathematics education. In response to that call, this paper illuminates the theoretical connections between the frameworks of two relational approaches to schooling, Restorative Justice in Education (RJE) and Cognitively Guided Instruction in Mathematics (CGI). Through discussing the intersections of the components of both frameworks and their shared vision of equity and agency for all students, this paper argues that integrating restorative justice into math instruction is not only possible, but necessary.

Paradoxes and dilemmas of family love
Authors: Manosalva Clara Ines Carreño , Buitrago Maribel Florián
Published: May 2022

The authors use Bordieu’s constructivist sociological perspective to question the social reproduction of the presupposition of family love in the Colombian context.  They examine three of the constitutive elements that define family love: the univocal and colonial position that fuses heteronormativity and family love; the accentuated inequality between a father’s love and a mother’s love; and family love that involves possession of the children.  The authors conclude by questioning their inflexible reasoning that defines family love and propose the right of mothers to legally recognize her children.

Economic costs and investment challenges of water infrastructure in South Africa
Authors: Ruiters Cornelius , Amadi-Echendu Joe
Published: May 2022

South Africa is facing significant water infrastructure investment challenges, at the levels of both water resources and services. Principles for water use pricing, charges, tariffs and use are enshrined in South African legislation, but implementation thereof is a major problem. This research paper addresses (a) economic costs, (b) efficiencies, (c) investment challenges and (d) the application and maximisation of economic tools. A total of 269 municipalities were sampled, and the research exemplified that South Africa was losing approximately US$0.617–1.033 billion/annum to various inefficiencies: (a) water use underpricing was approximately US$0.413 billion/annum. Water use charges and/or tariffs closer to cost-recovery levels would provide and ensure financial sustainability. (b) Return on capital investment inefficiencies contributed approximately US$0.926 billion/annum. Revenue far lower than the asset value is illustrative of unsustainable revenue for investments. (c) Non-revenue water was 36.8% and approximately US$0.402 billion/annum. Investments in water infrastructure maintenance projects will minimise distribution losses. (d) The multipliers were varied and substantially high – namely, 3–27. This illustrates the extent and seriousness of prioritising the implementation of water conservation and demand-management measures. (e) The capital investment gap was estimated at US$2.258 billion/annum for the next 10 years (2019/2020–2029/2030). Under-capital investments have serious downstream implications for socio-economic development and growth.

A new Nalassus Mulsant, 1854 (Coleoptera: Tenebrionidae) from Transcaucasia with a key to species from the Greater Caucasus and notes on the taxonomy, distribution, bionomics and trophic relations
Authors: Nabozhenko Maxim V. , Gagarina Ludmila V. , Chigray Ivan A.
Published: May 2022

A brief well-illustrated review of the tenebrionid genus Nalassus Mulsant, 1854 from the Greater Caucasus is presented. A new species, N. (Caucasonotus) negrobovi Nabozhenko, sp. n. is described from the alpine zone of Abkhazia. This species is similar to N. dombaicus (Nabozhenko, 2000), N. adriani (Reitter, 1922) and N. alanicus (Nabozhenko, 2000), but differs in the structure of eyes, antennae, pronotum and elytral interstriae. The following new synonyms are proposed after examination of a series of beetles and type specimens: Nalas­sus dissonus Nabozhenko, 2001 = Nalassus lutshniki Nabozhenko, 2001, syn. n.; Nalassus colchicus madlenae Nabozhenko, 2013 = Nalassus kartvelius Nabozhenko, 2013, syn. n.; Helops cambyses Seidlitz, 1895 = Cylindronotus ahngeri Medvedev, 1998, syn. n. Keys to species from the Greater Caucasus on males and females are given. New data on bionomics, landscape and habitat distribution and trophic relations are given. Interesting patterns are observed at the level of ecological groups: forest species feed mainly on corticolous foliose lichens from the family Physciaceae Zahlbr., while alpine Nalassus use saxicolous foliose lichens from the family Parmeliaceae Zenker; steppe species feed on terricolous foliose lichens at least from the family Cladoniaceae Zenker.
Supraspinatus Fatty Infiltration Correlation with Handgrip Strength, Shoulder Strength, and Validated Patient-Reported Outcome Measures in Patients with Rotator Cuff Tears
Authors: Mendez Greg , Manske Robert , Smith Barbara , Prohaska Daniel , Hearon Bernard
Published: May 2022

Introduction. The purpose of this study was to investigate the relationships between supraspinatus atrophy on magnetic resonance imaging (MRI) and other objective parameters in patients with rotator cuff tears. We hypothesized that high-grade supraspinatus fatty infiltration would be negatively correlated with handgrip strength, shoulder strength and patient-reported outcome measures (PROMs).

Methods. Patients with MRI-proven rotator cuff tears treated by a single sports medicine fellowship-trained orthopaedist at a single institution underwent comprehensive preoperative evaluation including bilateral handgrip and shoulder strength measurements with dynamometers and multiple online questionnaires from the Surgical Outcomes SystemTM(Arthrex, Naples, FL). Available shoulder MRIs were reviewed to grade supraspinatus fatty infiltration severity according to the 5-tier Goutallier system and an alternate 3-tier classification scheme. Difference analysis and Spearman (rho) rank order correlation were applied to the collected data to define the relationships between supraspinatus fatty infiltration and key variables including handgrip strength, shoulder strength and scores derived from the shoulder PROMs.

Results. Ninety of the 121 patients enrolled in the study had shoulder MRIs available for review. We found no correlation between supraspinatus fatty infiltration and handgrip strength, shoulder abduction strength or any of the 7 common shoulder PROM scores we evaluated. There was statistically significant albeit weak correlation between MRI-derived fatty infiltration and shoulder external rotation strength.

Conclusions. Contrary to our hypothesis, high-grade supraspinatus fatty infiltration is largely unrelated to and should not be considered predictive of handgrip strength, shoulder strength or common shoulder PROM scores.
Application of DEA to measure the productivity of the academic staff
Authors: Endovitsky Dmitry A. , Komendenko Sergey N.
Published: May 2022

Subject. Increasing the productivity of each academic staff member is an important condition for the achievement of high indicators by the university. The modern system of the effective contract in Russian higher education institutions provides great growth opportunities which need to be identified by analysts. Appropriate analysis methods are needed to secure a rational use of these opportunities. Objectives. Our goal was to find the best option for using the non-parametric method of Data Envelopment Analysis to solve the task related to the assessment of the productivity of each academic staff member at a middle-size university. Methodology. We used single-stage DEA models with constant and variable returns to scale, including non-discretionary outputs. The choice of a specific model was based on both quantitative and content interpretation of the obtained results. Results. It was established that R.D. Banker and R.C. Morey’s model can properly measure the productivity of academic staff and provide the university management with valuable information which can be used to efficiently manage the productivity of the employees. We identified the most probable difficulties regarding the application of similar models to a large sample of employees under real conditions. We obtained data on the productivity distribution and the dependence of productivity on occupation, which require further analysis. Conclusions. The basic single-stage DEA models are sufficient to measure the productivity of employees if non-discretionary outputs are carefully introduced and the solution's sustainability is controlled. However, the features characteristic of all DEA models cannot be ignored: they set achievable goals to improve the existing results, however they do not search new opportunities; they inform that the goals are achieved but not how significant the achieved results are for the university.

TÜRKİYE’DE COVİD-19 SALGINININ İLK DÖNEMİNDE UYGULANAN HÜKÜMET POLİTİKALARININ KRİZ YÖNETİMİ BAKIŞ AÇISIYLA İRDELENMESİ
Authors: Akgün Oğuz , Yalman Fuat
Published: May 2022

COVID-19 salgını, Dünya Sağlık Örgütü tarafından bir salgın olarak ilan edildikten sonra insanların yaşamları, aileleri ve toplumlar üzerinde büyük bir etkiye neden olmuştur. Enfekte olan toplam insan sayısının her gün artmasıyla birlikte COVID-19, uluslararası bir halk sağlığı acil durumu haline gelmiş ve virüs bulaşanlara sağlık hizmeti sağlamak, birçok hükümet ve organizasyon için en önemli öncelik olmuştur. Küresel COVID-19 salgınıyla mücadelede devletlerin başarı ya da başarısızlık durumları farklı açılardan tartışılmaktadır. Karşılaştırmalar ve ulaşılan sonuçlar farklı parametreler üzerinde değişmektedir. Bu karşılaştırmalar üzerinden elde edilen sonuçlara bakıldığında ise kriz yönetiminin başarısında belirleyici dinamiğin, güçlü devlet kapasitesinin ve uygulanan hükümet politikalarının olduğu görülmektedir. Güçlü devlet kapasitesinin ve uygulanan hükümet politikalarının önemi ise sağlık sistemi, ekonomi, eğitim, ulaşım, tedarik zinciri, bilimsel araştırma, dijitalleşme, etkin yönetim, güvenilir siyasi liderlik, iyi işleyen bir bürokrasi ve düzgün ve güvenilir yürütülen iletişim becerileri gibi birçok başlıkta test edilmektedir. Bu çalışmanın amacı, 2019 yılının Aralık ayında Çin’de ortaya çıkan ve kısa süre içerisinde küresel düzeyde yayılan ölümcül Covid-19 pandemisinin ilk dönemi (11 Mart-1 Haziran) ile ilgili Türkiye’nin mücadelesini ve uygulanan hükümet politikalarını, kriz yönetimi bakış açısıyla irdelemektir. Sonuç olarak Türkiye’nin krizi başarı ile yönetmesinde öne çıkan üç önemli faktörün göze çarptığı görülmüştür. Bunlardan birincisi, son 10 yıllık dönemde devlet ve hükümetin birçok krizle yüzleşmiş olmasından dolayı krizlere karşı ülkenin kazandığı bağışıklıktır. İkinci olarak, sağlık sektörüne özel bir önem verilmiş olunması ve sağlık hizmetlerinin sunumunda dünyanın önde gelen ülkelerinden biri olması Türkiye’nin krizle mücadelesini kolaylaştırmıştır. Üçüncü olarak ise, Cumhurbaşkanlığı Hükümet sistemine geçilmesiyle siyasal sistemin değişmesi bu süreçte devletin etkin ve hızlı karar almasını kolaylaştırmıştır.

The main reasons for fluctuations in research interest in the problem of will in the 20th century are analyzed, as well as the main directions of research of volitional regulation in modern foreign psychology and related phenomena, methodological approaches and theoretical concepts. The main approaches to the definition of will in modern foreign psychology are described: will as control of impulses, will as a mechanism for the realization of intention in action, will as control of action’s determination. The results of the analysis made it possible to substantiate the need to refer to the concept of will in modern psychology, as well as to formulate the main criteria that distinguish the will from other mental phenomena. The main prospects for the further development of will are outlined, associated with the transition to the study of will in the process of transformation of the system of relations between a person and the surrounding worlds in real life situations.
Semantic Aspects of Perception of Different Types of Residential Buildings According to the Associative Experiment
Authors: Kaptsevich O.A.
Published: May 2022

Visual environment of modern large cities is characterized by a wide representation of built elements. Some of them — residential buildings in particular — due to their prevalence, play a significant role in the citizens’ everyday perception experience. Moreover, the resulting image of such perception can be associated with some invariant semantic characteristics, including certain emotional coloring. That is, the perception of certain objects can set a certain emotional background. This aspect of human interaction with the city environment remains poorly understood. The aim of the study is to identify the semantic content of residential buildings perception and to trace the possible emotional effects of such perception. Two hypotheses were tested: first suggesting the difference in the semantic content of different houses perception images; second assuming the difference in the semantic content of images in different groups of respondents. 100 residents of Vladivostok city were studied, the average age was 38 years. The sample was divided into three age cohorts and included representatives of young, middle-aged and elderly people. The research was conducted on the basis of the Far Eastern Federal University, as well as online. Respondents ranked 10 photos of residential buildings, representing 5 categories, according to the degree of preference; then they were asked to write down the first associations that arose for each photo. The greatest inter-group consistency of images characterizes historical and “old” low-rise buildings. The perception of historical houses turned out to be the most emotionally positive and filled mainly with aesthetic connotations. “Old” low-rise and five-storey buildings revealed the most negative perception: the image of the former is dominated by the characteristic of poor well-being; the perception of the latter revealed their maximum unaesthetic. The results can be used in practices aimed to improve the visual environment of the city, in the implementation of social projects.

The article is aimed at analyzing the standardization process of the «Actual values differential scale» method. The article presents the materials of a step-by-step empirical study based on a sample of respondents from the Siberian Federal district. At different stages, the study involved 6439 people (51% females; 49% males) aged 20 to 54 years (M=38.12; σ = 0.15). Verification of the empirical construct included dispersion, exploratory, correlation, and factor analyses, as well as the assessment of distribution, excess, and asymmetry of personal and professional value categories descriptors. Evidence of reliability and constructional and criterial validity is provided. The results obtained allow us to speak about the diagnostic potential of the developed methodology, which allows us not only to study the set of the significant values, but also to determine the type of the relevant value system of an individual. The method can be used for solving scientific and practical problems, both in psychology and other scientific fields.
Design Simulation and Assessment of Energy Efficient FBMC System for 5G Communication System

Published: May 2022

Channel capacity and Peak Average to Power Ratio (PAPR) are essential elements in offering dependable communication through wireless medium in wireless communication system. The rating of an amplifier in an Orthogonal Frequency Division Multiplexing (OFDM) system, as well as prospective future candidates of 5G systems such as Filter Bank Multicarrier (FBMC) and Universal Filtered Multicarrier (UFMC), affected by a high peak to average power ratio. The demand for channel capacity fluctuates due to the growing number of wireless network users. This paper recommended a low PAPR FBMC method, showing excellent performance in terms of PAPR reduction gain, overhead computation complexity and overhead SI compared to the current PAPR reduction scheme. In order to further increase the reduction in PAPR we have developed four variants of FBMC waveforms for DFT expansion, ITSM and the selected with the smallest peak capacity. In order to further reduce the PAPR rate of DFT expansion we have produced four different versions. After implementation of the proposed algorithm, the PAPR of the FBMC method has been considerably reduced. Following use of DFT propagation and ITSM conditioning, PAPR was decreased by 25 percent. The side data, which is persistent with traditional PAPR reduction techniques like cutting, partial transmission series, and selective mapping, is also disabled. The proposed device improves the transmitters' lifetime and efficiency through waveform accuracy. The study begun was planned to reduce the limitations of contending waveforms in order to create a resourceful communication system.
Recognizing Fake Headlines Using Clustering Algorithms

The credibility of the news sources has hit a new low during the COVID-19. Hence, it is necessary to check for facts before trusting the news. Clustering is extremely important for analysing data, making predictions, and overcoming data abnormalities. So, in this work, the two most prominent clustering algorithms, K-Means and K-Medoids, are tested on a dataset, and K-Means outperforms k-Medoid. We now utilized supervised classification methods like Logistic Regression, K-Nearest Neighbours, and Support Vector classifier to train on the same news headlines we used for clustering with the 'Prediction' column, and then chosen the technique with the highest accuracy. The Support Vector Classifier had the maximum accuracy of 94.93 percent, according to the test. We have developed is a hybrid model consisting of an unsupervised K Means clustering algorithm and a supervised Support Vector classification algorithm. The K Means algorithm organizes the news headlines into clusters by capturing the usage of certain words and the support vector algorithm learns from those clusters to predict the categories into which the unseen news headlines belong to.
The Mediation Effects of Capital Structure: Evidence from Malaysian and Indonesian Economic Sectors

We study the comprehensive, simultaneous interrelationships between countries, economic sectors (i.e., primary, secondary, and tertiary sector), capital structure and firm financial performance, especially involving the mediation effects in different sectors. We find that some determinants of capital structure do not only directly enhance firm financial performance. Firm financial performance is also influenced by how capital structure from the product category in the economic sectors have been financed. We find a significant relationship between capital structure and firm financial performance in the secondary and tertiary sectors but not for the primary sector. We find that the secondary sector tends to use internal financing while the tertiary sector tends to use external financing to enhance firm financial performance. Our results also reveal that the effect of capital structure on firm financial performance tends to be mediated by firm- and country-specific attributes, as well as by the sector in which they operate. A closer examination of the data showed that in the economic sectors, we find robust results that there are not just positive direct and indirect effects, but also negative direct and indirect effects. It should be well understood by financial managers that secondary and tertiary sectors plays an important role in the mediation effect. The contribution of this study is to help the firm manager to make a good decision on the proportions of their capital structure.

This study determined possible intellective indicators that could influence the engineering proficiency exams. The intellective attributes of the respondents considered were type of high school graduated, SHS strand, General Weighted Average (GWA), OLSAT Scores, scholastic achievement, and course while engineering proficiency examinations was measured in terms of general education and specialized subjects. 

Quantitative research design was utilized in this study. Total enumeration of the 156 freshmen engineering students were the respondents of the study. The OLSAT and the departmental made questionnaires were the main tool. Frequency counts and percentages, weighted mean, t- Test, and ANOVA were utilized.

Findings revealed that the respondents were graduates of public high schools. Their course is parallel to their SHS academic strands. They performed satisfactorily in high school and also in their freshmen scholastic achievement. Mostly wanted to become civil engineers however, they achieved low performance in their OLSAT. Respondents met the standards required by the institution as prescribed by Commission on Higher Education. The BSME students outperformed the other two engineering courses; Students who have low high school GWA and scholastic aptitude displayed higher performance in the engineering proficiency examinations; Proficiency of the students who graduated from public and private in are the same; Students from the engineering courses, and who underwent different senior high school strands displayed the same proficiency.

The intellective correlates to the proficiency exams were their GWA and Scholastic Achievement. Skills enhancement of the engineering performance to track the student’s abilities to level up achievement and the guidance office should consider bridging programs.
