Published: July 2020

The recognition of science and technology as a risk activity, focusing on results rather than procedures, means that researchers are more effectively engaged in activities involving innovation. The purpose of this article is to analyze the applicability of law known as the Legal Framework of Science and Technology, and it was constructed with bibliographical support seeking to contribute to a different view of the control organs regarding the research. The new Brazilian legislation brings with it the expectation that research and market have a process of approximation, reducing the distance between the knowledge produced in universities and their transformation into wealth. The possibilities arising from the new legislation tend to have effects in solving problems of quality, productivity, cost reduction, with the possibility of incorporating benefits to production and competitiveness, with the introduction of technology, methods and processes aligned with lean production. It concludes that the Legal Framework for Science and Technology, with its specific purpose of reducing bureaucracy in the country's research and innovation activities in general, is an important instrument in the integration of the academic and scientific community at all levels, and companies, representing a new path to boost the process of education.
Effect of Learning Method Schoology Applications and Learning Style on Student Learning Outcomes
Authors: Sitinjak Anna Angela
Published: July 2020

This type of research is a quasi-experimental research. The purpose of this study is to determine whether student learning outcomes with the LMS method (using Schoology) are higher than conventional and whether there is an interaction between learning methods with student learning styles. The population of this study were all students of the mechanical engineering study program at the PTKI campus Medan. The sampling technique used was cluster random sampling. The control class and experimental class selected each consisted of 20 people. The instrument used to measure students' mathematical achievement is the essay-test. The instrument used to measure student learning styles is a questionnaire. The normality test used is the Lilliefor test and homogeneity test using the Fisher test. Then the ANOVA test was performed with a significance level of 0.05. The results showed that students who were taught using Schoology had high learning outcomes compared to conventional learning and visual learning styles were highest in learning outcomes than other learning styles. But learning styles and learning methods don't have interactions. For further research, it can be done with different learning models and adding other variables to see the readiness of our human resources in facing the industrial world.

Published: July 2020

Strawberry culture is of extreme economic importance, especially for small producers, as it has the capacity to add value to small family farms, in addition to absorbing family labor. Principal component analysis (PCA) is a multivariate technique for modeling covariance structure, where a basic idea is to find latent variables that represent linear combinations of a group of variables under study, which in turn are related between itself. In this way, the objective of the work was estimated, through the analysis of main components (PCA), as relationships between development variables, products and fruit quality in different strawberry cultivars. The design used was a randomized block with 11 treatments, consisting of strawberry cultivars of Italian and American origins, with four replications. During the culture cycle, the following variables were evaluated: phyllochron, number of commercial (FC) and non-commercial (FNC) fruits, mass of commercial (MFC) and non-commercial (MFNC) fruits, total titratable acidity (AT), total soluble quantities (SST) and total soluble ratio, titratable acidity (SST / AT). The relationships between the variables were evaluated by the PCA analysis and the results were plotted on the Biplot graph. From the analysis, it was possible to identify the relationships between the variables that show how to cultivate the same photoperiod and the same characteristic origin. Growing short photoperiods are more productive, for example, as the neutral photoperiod has less phyllochron and less acidity. The increase in soluble solids can cause a reduction in acidity, which is one of the characteristics that add flavor to the fruit.

Communication is very critical in primary school management by ensuring that there is improved efficiency. However, in many primary schools in Thika West Sub-county encounter challenges which border on school management such as unhealthy staff relations, imprudent use of financial resources, poor maintenance of facilities, imprudent time management and under-utilization of instructional materials are on the rise. Thus, this study sought to assess the influence of headteachers’ communication planning practices on management performance in public primary schools in Thika West Sub-county, Kiambu County, Kenya. The study was guided by the communication theory and school management theory. The study adopted mixed methodology and concurrent triangulation research design. Qualitative data were analyzed thematically along the objectives and presented in narrative forms. Quantitative data were analyzed descriptively using frequencies and percentages and inferentially using ANOVA Test Analysis using Statistical Packages for Social Science (SPSS Version 23) and presented using tables. The study established that headteachers’ communication planning practices influence on management performance in primary schools. The study recommends that headteachers should ensure that they design the content of message to be relayed and also identify the specific recipients of their information to be communicated. Headteachers should adopt layers of communication which are efficient and provide immediate and objective feedback. Headteachers should adopt forms of communication to suit every occasion to avoid interruptions. Headteachers should adopt a feedback mechanism which guarantees efficiency and prudence in school management.

VISIBILITY OF HOSPITALIZED CHILDREN
Authors: Silva Milene , De Almeida Ordália Alves , Melim Ana Paula Gaspar
Published: July 2020

The article results from a research developed in the Postgraduate Program in Health and Development of the Midwest Region, at the Federal University of Mato Grosso do Sul, carried out in the hospital classes of two public hospitals in Campo Grande / MS, between 2014 - 2016. We carried out a bibliographic survey on the topic, allowing us to reflect and discuss the visibility of hospitalized children. We verify how the children's learning process takes place in the hospital environment. The right to basic education belongs to all children, including those who are away from school due to illness. It is necessary to think about the locus of pediatric hospitals in order to develop activities in which the hospitalized child feels productive, in development, and with activities similar to other children of his age. The child must participate in activities that allow him to live on equal terms with other children and have the opportunity to be included in the knowledge acquisition process. Ceccim et al. (1997) affirm that the hospitalized child cannot be doubly penalized: to be sick and to be away from school, friends, games and organizations of space and time. Education is a right for all and a duty of the State and the family and is expressed as a right to learning and schooling. These rights are consolidated in article 214 of the Federal Constitution when expressing that the actions of Public Policies should lead to the universalization of specialized school attendance and in the Law of Guidelines and Bases of National Education in art. 5, by ensuring that the Public Power will create alternative forms of access to different levels of education. This service is characterized as Special Education for serving children considered to have special educational needs as a result of having curricular difficulties due to conditions of specific health limitations recovering the child in an inclusion process offering learning conditions.
adoption of an indicator panel in educational management to decision-making support
Authors: Zamberlan Miguel Fabrício , Watanabe Carolina Yukari Veludo
Published: July 2020

The use of technology to assist in the performance of daily activities and to carry out communication between individuals has become a necessary task in the face of technological advances. In the context of public institutions, the insertion of technology is also based on the possibilities of making the activities of this sector more efficient and better quality, in addition to allowing greater transparency and accessibility of information for society. For public managers, the information and communication technology tools allow for a more accurate assessment of the variables and possibilities involved in a decision-making process and, thus, to make better decisions in a sector whose main customer is society (users). Therefore, this paper aimed to analyze the use and acceptance of a decision support tool in a public educational institution called the Indicators Panel. For this, the Unified Theory of Acceptance and Use of Technology (UTAUT) was used, and the results were measured using the paraconsistent logic. The results indicate that it is possible to consider the use and acceptance of the decision support system in the public educational institution by reducing the propositions of the UTAUT Model in three factors: Usability, Performance, and Relationship. Regarding the UTAUT Model, it was found that the moderating variables of gender, age, and experience do not significantly influence the adoption of the decision support system. It is important to note that managers point the tool as very important for the development of their activities and emphasize that ease of use is one of the main points for the adoption of technology.

Distance-learning graduate programs go beyond the limits of academic training, restricted to obtaining a degree. Challenges and overcoming occur, not only in the search for qualification, for a career plan and following the company's' remuneration policy, but also due to the physical distance from major teaching centers. The great proposal is to supplant the frontiers of knowledge, in places where there is immense biodiversity, in contrast to geographical isolation. The objective of the study is to present the challenges and perspectives of the lato sensu graduate program at a University of the Brazilian Amazon, in the Municipal Public Management course in the state of Rondônia. The methodology used was that of review, as it seeks to describe, analyze and discuss scientific and technological knowledge already published. The review is basic and, it is expected that it will serve as support for scientific research and also, as support for theoretical reference. The course presented as a result works aimed at the better performance of the Management of the Municipalities of Rondônia. The research work developed by the students represents a local reality diagnosed with the search for managerially planned solutions.

Authors: Marques Marcos , Nascimento Claudete Catanhede do , Araujo Roberto Daniel de
Published: July 2020

The wood residues resulting from the operational phases in companies in the forestry market are normally considered by-products and, therefore, are discarded or reused for energy production, however, this material has a greater potential, such as the generation of new products through agglutination, which may generate a new segment in the wood industry, causing competition between products of native and planted species. This research aimed to develop agglomerated panels using residues of two tree species from the Amazon (Dinizia excelsa Ducke and Manilkara huberi (Ducke) Chevalier) and a mixture of commercial Amazonian species of high density, with the purpose of greater added value and a possible solution to reduce the negative environmental impacts of carbon emissions. The experimental design consisted of three treatments with five repetitions in each. Experimental panels were produced with a nominal density of 0.80 g/cm³, using castor oil-based resin with 10% percentages. The panels were pressed with a pressure of 10 MPa, temperature of 100ºC and with a pressing time of 10 minutes. The evaluations of the results obtained were compared with the ANSI A208.1 / 2009 standard and with the literature on agglomerated panels of tropical species. In physical properties, the panels showed compliance with the values found in the literature, however, they are outside the standard of the norm. Regarding the mechanical properties, the MOR values classify the panels in the medium to high density standard in accordance with the standard.  The results of the MOE are superior to those of the existing literature, with emphasis on the perpendicular traction that presents values consistent with the literature. The machining evaluations carried out according to ASTM D 1666-11 / 2011, show a good quality in the finish. In general analysis and in compliance with the regulations, all panels have economic viability and potential for industrialization.

The research objective of this study was to evaluate the use of Physical Education classes as didactic laboratory for lessons in Mathematics, presenting an alternative way to conduct classes, mainly of quadratic functions, illustrating basic concepts such as graphs plotting and determination coefficients, analyze if such use achieves some of the goals of using a Didactic Laboratory in addition to research ways to interdisciplinary with Physics. Discusses an action in which students work in groups to solve problems proposed based on empirical data obtained through play activities and measures of athletics values practiced by the students allowing may have the opportunity to produce arguments and more meaningful answers, which would improve the overall learning. The athletics and recreational activities are then used as problematic objects both empirically and qualitatively. As a result, it was observed that some of the objectives of a Didactic Laboratory are achieved when using the Physical Education classes and it appears that this feature is much more available in public schools than they are equipped with a science laboratory.

Published: July 2020

The increase in resistance of pathogenic microflora to antibiotics over the world has become one of the challenges for biomedical science. Therefore, further development of antimicrobials and their use in various fields of medicine are extremely important. There are a wide range of antiseptic preparations in different fields of clinical medicine (octenisept, eludril, triclosan, myramistin, chlorhexidine, bigluconate-syn. hexinone, hibiscrab, hibitsan, eugel, fervex and others) in our country today. In 1985 the researchers of the Department of Skin and Sexually transmitted diseases, UMSA, created an antiseptic for treating venereal diseases. The name "Cidipol", proposed by the author, prof. V. G. Kravchenko, was approved by the Nomenclature Commission of the Pharmacological Committee, the Ministry of Public Health of the former USSR. The medicine as an invention was registered at the International Patent Centre (Geneva, Switzerland), and patents for the invention were obtained in Ukraine, the USA and the Russian Federation. In the United States, the drug has been reported as a preparation for individual prevention of sexually transmitted diseases and the treatment of urogenital trichomoniasis in women. Considering that antiseptics can produce an effect on the wide range of microbial flora, it is quite relevant to study the effect produced by Cidipol on certain types of bacteria and fungi. The purpose of the study was to investigate the fungicidal and bactericidal action of Cidipol on a number of gram-negative and gram-positive microorganisms. The study was carried out at the Department of Microbiology, Virology and Immunology, UMSA; we used museum strains of the following microorganisms: C.albicans ATCC10231, E.coli ATCC25922, S.aureus ATCC25923, E.faecalis ATCC29213, M.luteus ATCC4698, S.epudermidis ATCC14990. The antibacterial composition, prepared ex tempore according to the prescription "Cidipol", was used: 0.3% ciminal (p-nitro-alpha-chloride aldehyde), 5.0% dimexide, 94.7% polyethylene oxide. The investigated museum strains of C.albicans ATCC10231, S.aureus ATCC25923, E.coli ATCC25922, were found out to be sensitive to the effect of Cidipol; the fungicidal effect of the Cidipol composition exceeded its bactericidal effect in 4 times. The strains of E.faecalis, M.luteus, and S.epidermidis were the least sensitive. Conclusions. The results of the studies have demonstrated the presence of pronounced antimicrobial effect of Cidipol to museum microorganism strains with different levels of sensitivity.

Published: July 2020

In-depth study of the peculiarities of the morphological, topographic and anatomical relationships between fascia, muscles, vessels, nerves, cellular spaces and organs of other parts of the human body requires applying an appropriate methodology of morphological research. According to some researchers, the superficial, pretracheal, and prevertebral plates of the cervical fascia develop depending on the origin and morphogenesis of the respective groups of neck muscles. Obtaining data on the development of topographic morphology of the cervical fascia and interfascial cellular spaces of the anterior and lateral areas of the neck during the fetal period of human ontogenesis is an important area of fetal anatomy and surgery and can be used for age comparison. The purpose of the study was to clarify the peculiarities of the development of the topographic morphology in the cervical fascia and interfascial cellular spaces of the anterior and lateral areas of the neck in human fetuses of 4-10 months of gestation. The study was performed on 75 human fetuses of 81.0-375.0 mm parietal coccygeal length without external signs of anatomical abnormalities or developmental anomalies of the cervical region by preparing microscopic slides of organs and structures of the anterior and lateral areas of the neck. The samples taken from fetuses weighing more than 500.0 g were investigated directly at the Chernivtsi Regional Paediatric Pathological Bureau according to the association agreement. The material was also taken from the M.G. Turkevich Museum of the Human Anatomy Department, Bukovinian State Medical University. The macroscopic and microscopic investigation of the cervical region in human fetuses of 4-7 months revealed thin, semitranslucent plates of the cervical fascia: superficial, middle (pretracheal) and deep (prevertebral). In fetuses of 8-10 months in the anterior area of the neck, the plates of the cervical fascia were clearly seen and shiny. Subcutaneous, or superficial, and intracervical fascias were fascias propria of the neck, and having no clear boundaries passed into adjacent areas. In the fetal period of human ontogenesis the interfascial cellular spaces of the anterior and lateral areas of the neck develop including suprapectoral, anterovisceral, extravisceral, antescalenous, interscalenous cellular spaces and sheath of vascular-nervous bundles of the neck. During the fetal period of human ontogenesis, there is a pronounced variation in the development and location of the plates of the cervical fascia. The authors of this study state that the research and result publication have no conflicts regarding commercial or financial relations, relations with organizations and/or individuals who may have been related to the study.

Authors: Yavtushenko I.V. , Kostenko V.O.
Published: July 2020

This study was aimed as investigating the effects of modulators of transcription factors NF-κB, AP-1 and Nrf2 on the survival rate of white rats and the development of neurological deficits following the simulation of traumatic brain injury (TBI). The study included 110 white Wistar male rats weighing 180-220 g, divided into 6 groups. Control group involved animals after the TBI injury simulation (n=30). The animals of other groups (16 rats in each) were intraperitoneally injected with modulators of transcription factors after the simulation of the trauma for 7 days: ammonium pyrrolidine dithiocarbamate, an inhibitor of nuclear translocation NF-κB, was injected in a dose of 76 mg/kg; AP-1 SR 11302 inhibitor – in a dose of 1 mg/kg; Nrf2-ARE system inductors as dimethyl fumarate in a dose of 15 mg/kg in a 10% dimethyl sulfoxide solution and epigallocatechin-3-gallate in a dose of 1 mg/kg. The test animals were also injected with a water-soluble form of quercetin (corvitin), which acts as an NF-κB inhibitor and Nrf2 inducer, in a dose of 100 mg/kg (10 mg/kg in terms of quercetin). The animals in the control group were injected intraperitoneally with 1 ml of isotonic sodium chloride solution instead of the tested compounds mentioned above. It has been found out that on the 7th day after the simulation of moderate TBI most animals showed signs of neurological deficit including impaired muscle tone (83.3%), impaired coordination (83.3%) and pain reaction (66.7%). Integral indicator of neurological deficit by Todd et al. 100-score grading scale was 51.33±2.95. The use of inhibitors of transcription factors NF-κB (ammonium pyrrolidinedithiocarbamate) and AP-1 (SR 11302), the Nrf2-ARE system inducers (dimethylfumarate and epigallocatechin-3-gallate) and the water-soluble form of quercetin (corvitin) increases rats’ survival rate, significantly limits their signs of neurological deficit and its integral index.
PSYCHOLOGICAL NATURE AND STRUCTURE OF MOTIVATION

Published: July 2020

The aim of this study is to provide theoretical rationale for integrative model of motivation as a unified structure that ensures achieving different types of results of human activity. The methodology of this study includes induction and deduction methods, scientific literature analysis, as well as comparative analysis. There have been defined the notions of «motive», «need» and «motivation», in particular, we have identified major differences and similarities between these concepts as well as their points of contact. The motives have been classified into conscious and unconscious with subsequent justification of such division. The article discusses the difference between external and internal motivation and proves the particular effectiveness of the latter. There has been analyzed the structure of the human motivational system encompassing all its components such as interests, needs, values, attitudes, beliefs, stereotypes, etc. We have identified the basis of motivational system, which determines personality's orientation and its peripheral parts. There has been conducted a comparative analysis of major motivation theories, which explain the structure and significance of human needs, their relationship with motivation to act. For example, we found out that K. Alderfer's ERG paradigm corresponds to A. Maslow's hierarchy of needs paradigm in regards to the main groups of needs. However, most theories of motivation use different criteria for distinguishing needs which makes it more difficult to compare them. For instance, D. McClelland's acquired needs paradigm is based on identifying the needs for power and complicity, while Porter-Lauler model is based on analysing concepts of expectations and justice within the motivational system of an individual. However, all authors seem to agree on one thing: motivation is a complex system-based integrative psychostructure that encourages a person to perform various types of activities. Thus, we can conclude that despite various explanations of the concepts of «motive» and «motivation», different criteria for distinguishing needs and interpreting their impact on motivation, human motivational system is a holistic unified structure that affects human behaviour in a specific way.

Published: July 2020

Svako poduzeće nastoji organizirati svoje poslovanje primjerenim upravljačkim modelom koji se provodi kroz upravne organe u odnosu na trenutno poslovno okruženje. Temeljni upravni organi u mnogim poduzećima su skupština društva, upravni odbor i nadzorni odbor. Naglasak u ovom radu bio je na analizi spolne zastupljenosti u upravljačkim pozicijama odnosno postoji li razlika u ostvarivanju profitabilnosti kod velikih poduzeća u Republici Hrvatskoj u odnosu na zastupljenost žena i muškaraca u upravljačkim pozicijama. Predmet ovog rada je prepoznati važnost spolne zastupljenosti u upravljačkim pozicijama kod velikih poduzeća u Republici Hrvatskoj. Problem ovog rada je utvrditi na koji način spolna zastupljenost u upravljačkim pozicijama doprinosi postizanju veće profitabilnosti kod velikih poduzeća u Republici Hrvatskoj. Temeljna hipoteza rada je da postoji statistički značajna razlika između spolne zastupljenosti u upravljačkim pozicijama i profitabilnosti velikih poduzeća u Republici Hrvatskoj. Istraživanje se provodi na 148 velikih poduzeća iznad 600 zaposlenika u Republici Hrvatskoj. Rezultati istraživanja pokazali su da ne postoji statistički značajna razlika između profitabilnosti i spolne zastupljenosti u upravljačkim pozicijama kod velikih poduzeća iznad 600 zaposlenika u Republici Hrvatskoj. Ovo je istraživanje osnova za daljnja istraživanja na ovu temu u Republici Hrvatskoj.

Published: July 2020

Turizam i djelatnosti povezane s turizmom značajan su čimbenik hrvatskog
gospodarstva, s jasnim naznakama nastavka takvih trendova i u budućnosti. Istraživanja pokazuju kako se udio turizma u hrvatskom bruto
domaćem proizvodu povećao, a sve su više primjetna nastojanja za podizanjem kvalitete turističke ponude i produžavanja turističke sezone.
Nositelji takvih inicijativa od kojih se očekuju povećani povrati u dugom roku zasad su uglavnom turistička poduzeća s najvećim financijskim
potencijalom. U ovom radu autori istražuju je li kretanje cijene dionica takvih trgovačkih društava povezano s povećanim prihodima u vrijeme sezone, odnosno je li kretanje cijene povezano sa sezonskim oscilacijama ili je povezano s njihovom dugoročnom poslovnom politikom. Istraživanje je pokazalo da sezonske promjene imaju određeni utjecaj, ali nedovoljan da značajnije determiniraju kretanje cijene vrijednosnica
na financijskom tržištu promatranih poduzeća. Unatoč značajnom povećanju prihoda, trend je silazan, a naznake njegovog obrata u kratkom
i srednjem roku nisu uočene, što može ukazivati na nepovjerenje ulagača
u takav oblik razvoja turističkih poduzeća.

Suradnja s udrugama u provedbi javnih politika najčešće se očituje kroz različite oblike financijske i nefinancijske podrške koje jedinice lokalne samouprave pružaju programima i projektima od interesa za opće dobro. Ta vrsta međusektorske suradnje ima veliki potencijal za generiranje brojnih pozitivnih promjena i stvaranje prijeko potrebnih sinergija za održiv društveni i gospodarski razvoj. U kojoj će mjeri taj
potencijal biti ostvaren, uvelike ovisi o kvaliteti kriterija, standarda i postupaka za dodjelu financijskih i nefinancijskih podrški, kao i organizacijskim i ljudskim resursima unutar javnih institucija nužnih za uspješno praćenje i vrednovanje ugovorenih modela podrške. Glavni cilj ovog rada je na primjeru pokazati kako je moguće unaprijediti kvalitetu donošenja odluka
u lokalnoj samoupravi primjenom metoda odlučivanja u procesu donošenja odluka o financiranju udruga u kulturi. Na primjeru će se odrediti važnost (težinski koeficijenti) kriterija i podkriterija za procjenu kvalitete

projekata/prijava udruga u kulturi (N = 18) s područja Grada Zaboka. Isto tako, u ovom radu AHP metoda primijenit će se za izradu modela rangiranja programa/projekata u kulturi koji su financirani iz proračuna
Grada Zaboka. Model će se validirati na povijesnim podacima iz 2018. godine.

Published: July 2020

Javni sektor u suvremenom poslovnom okruženju biva izložen isti m utjecajima globalnog poslovanja, društvenih i kulturnih promjena kao i privatni sektor, te se sukladno tome prilagođava postojećim socio-ekonomskim potrebama. Zadaća je javnog sektora da zajedno s privatnim sektorom unaprjeđuje društvo, stvara predispozicije društvenog
rasta i razvoja, utječe na pozitivno određenje nacionalnih ekonomija i rada poslovnih subjekata u svrhu stvaranja novih vrijednosti. Također, kao javni servis, javni sektor osigurava pravovremeno, kvalitetno i sadržajno ostvarenje interesa građana. Stoga je nužno definirati i razvijati oblike javnog menadžmenta
koji se mogu odgovarajuće prilagoditi promjenama okruženja i djelotvorno upravljati različitim aspektima internih funkcija javnog sektora. Cilj rada je istražiti temeljna obilježja suvremenog javnog sektora i na temelju toga odrediti potrebne modalitete javnog menadžmenta. Metodologija istraživanja temelji se na analizi strukture javnog sektora s osvrtom na Republiku Hrvatsku, uz pregled javnih upravljačkih odnosa koji u njemu trenutno postoje. Pritom se uvažava diverzifikacija javnog sektora na opću državu (javnu upravu) i javna (društvena) poduzeća. Svaka razina javnog sektora ima svoje podrazine djelovanja u različitim vidovima djelatnosti sa specifičnim ciljevima i zahtjevima, što pred javni menadžment postavlja uvjet uske specijaliziranosti, multidisciplinarnosti i interaktivnosti s različitim subjektima poslovnog okruženja. Rezultati istraživanja očituju se u predlaganju razvojnog modela menadžmenta s ciljem povećanja reagibilnosti javnog sektora na promjene u suvremenom društvenom i poslovnom okruženju. Istovremeno se kao glavni zaključak nameće da je razvoj transparentnog javnog menadžmenta preduvjet razvoja javnog sektora koji može uspješno zadovoljavati potrebe i pratiti interese svih njegovih korisnika u 21. stoljeću.

The domain of occupational safety and health at work is put for regulation through directives by founding agreements. This means that the institutions of the European Union prescribe minimum standards of safety and health at work through directives and Member States need to accomplish goals that a particular directive pursues. At the same time, this means that each Member State can also set stricter standards than the ones prescribed through directives and for this reason some differences in regulations of individual Member States can be noticed. In this paper, authors focus on the role of occupational safety specialist and the manner in which the Republic of Croatia and the Portuguese Republic, in their legislation, prescribe obligations of the employer in terms of contracting the performance of occupational health and safety tasks with an occupational safety specialist or an external service. Authors furthermore examine required conditions which occupational safety specialist must meet to perform those tasks. Apart from outlining the Croatian and Portuguese legislation, authors also present and define fundamental similarities and differences in the regulations within this domain of security legislation.

Authors: Petrov M. , Fatkieva R.
Published: July 2020

An approach to predicting the development of attacks on network resources using distributed attacking tools is presented. Distinctive features of attack scenarios are shown. A model of the functioning of a network with distributed attacking elements is described. It is shown that dynamics modeling using the entropy approach to stability assessment does not make it possible to identify the presence of an attack. A method for detecting a focal point carrying out an attack is proposed.

Modeling of Amplitude Characteristic in Radio Channels of Code Division Multiple Access Systems
Authors: Gurevich V. , Egorov S.
Published: July 2020

In CDMA radio access systems, amplitude distortions in a nonlinear amplifier (NA) of a group signal lead to bit errors at the outputs of subscriber channels. To assess the permissible distortion limits and their influence on the transmission quality of subscriber signals, an electronic model of the amplitude characteristic (AC) and analytical relations are needed that relate the probability of an error when registering the output signal of the communication channel with the nonlinearity of the AC NA and other destabilizing factors. The article compares alternative mathematical models of AC NA. In contrast to traditional methods of analysis, usually limited to the choice of models with fixed parameters, a method for variably determining the parameters of AC is considered. The results are: a comparison of known methods for approximating the AC of broadband nonlinear power amplifiers of radio signals is given, an algorithm for selecting model parameters for CDMA systems with QAM using the Rapp model is proposed.
Methodological Approach to Integrated Effectiveness Assessment Apply of Aviation Systems with UAVs. Part 1. Evaluation Methods for Effectiveness of Solving Radio Communication and Remote Monitoring Tasks.
Authors: Pantenkov D.
Published: July 2020

Currently, the use of aviation systems with unmanned aerial vehicles (UAVs) of various classes and special purposes has gained particular relevance and practical importance in the interests of both special customers and civilians. Modern UAVs are used both individually and as part of a group, they can carry several target loads on board simultaneously, they are built on various physical principles: a multifunctional optoelectronic system, a digital aerial system, an airborne radar station, a radio and electronic reconnaissance system, and a system communications for transmitting data from target loads (sensors) to a mobile device (for example, a tablet) to a remote subscriber, etc. However, the question of determining the effectiveness of solving both individual UAV targets and finding an integrated assessment of the effectiveness of using aviation complexes with UAVs when solving a set of targets (sequentially or sequentially-in parallel in time) taking into account their priority and a number of other factors. This article structurally consists of three parts. In the first part, we can observe a scientific and methodological approach to determining the effectiveness of solving particular communication targets and remote monitoring by a complex with UAVs according to the probability of their solution is developed. In the framework of this approach, a mathematical apparatus has been developed for the functional depend-ence of the probabilities of solving particular target problems with the design parameters of target loads as part of the UAV, taking into account the peculiarities of its functioning and under the conditions of existing limitations and assumptions. The scientific and methodological approach allows already at the stage of the formation of the tactical and technical task for the complex with UAVs to obtain, using the calculation method, quantitative estimates of the probabilities of solving particular targets taking into account the technical backlog of industrial enterprises for key components of the complex (target loads, communications equipment complex, etc.). The methodological apparatus developed in the article is universal and invariant with respect to input parameters, i.e., the number of tasks to be solved, the stages of operation of the complex with UAVs, and can be easily adapted to new conditions of use. It should be noted that the result of the article is the methodological apparatus for finding exactly the integral estimate. Finding performance assessments for the group use of UAVs, as well as taking into account possible countermeasures, is beyond the scope of this article and is a direction of further research on this topic.
Positioning Accuracy Evaluation of Radio Emission Sources Using Time Difference of Arrival and Angle of Arrival Methods. Part 3. 3D-Simulation
Authors: Fokin G. , Lazarev V.
Published: July 2020

This work completes a series of studies evaluating positioning accuracy of radiation sources using the differential-range and/or goniometric method for the spatial scenario. A complex of models and methods is proposed for estimating the limits of positioning accuracy by the metric of the scattering ellipsoid of the lower Cramer – Rao boundary and circular spherical deviation in 3D. Based on the developed tools, a quantitative and qualitative analysis of positioning scenarios in superdense 5G radio networks was performed. The assessments made it possible to verify the requirements of 3GPP specifications for the accuracy and reliability of geolocation applications and services in the promising 5G ecosystem.
Communicative instruments of integration of the Ukrainian question into British political discourse
Authors: Zaytseva Zinaida
Published: July 2020

It was established that the British direction of informing about the Ukrainian national movement was an integral part of the program of the activities of the Ukrainian Information Committee (Lviv, 1912) to familiarize Europe with the situation of Ukrainians in two empires. The reasons that complicated the distribution of adequate information
about Ukraine in the British information space were revealed. They lay in both the plane of British society and the socio-political situation in Ukraine. The importance of the research of the English Slavist W.R. Morfill is singled out. The establishment of contacts between Ukrainian politicians and the representatives of the English press has been followed, and the purpose of the creation and operation of the Ukrainian Committee in London has been outlined. It is established that the range of communicative tools available to Ukrainian politicians at the beginning of the twentieth century. included interpersonal contacts, press organs, public lectures, public institutions. Due to the press performances, the British knowledge of Ukraine on the scientific and academic format (Slavist W.R Morfill) was partially transformed into a popular science and political (journalist J. Raffalovich).
Virtual CPU Scaling for Efficient Server Power Consumption in Cloud Data Center
Authors: Bhaya Noora N. , Ahmed Rabah A.
Published: July 2020

Cloud computing is a fast-growing technology used by major corporations these days because of the flexibility framework it provides to consumers. Cloud technology requires large data centers consisting of multiple IT equipment and servers. One main problem with these data centers is the vast amount of power consumed during servers operation. This reduces financial benefit and increases the need to produce more energy to cover the needs of operating the cloud infrastructure. This paper proposes an approach for managing the virtual central processing unit (vCPU) of a virtual machine to improve server power efficiency. A framework is used to study the proposed approach while processing different types of workloads widely found in most general-purpose cloud computing applications. Results indicate an improvement in server power saving.

Authors: Singh Pradeep K. , Chen Zu-Lin , Strickland Sidney , Norris Erin H.
Published: July 2020

An activated plasma contact system is an abnormality observed in many Alzheimer’s disease (AD) patients. Since mild cognitive impairment (MCI) patients often develop AD, we analyzed the status of contact system activation in MCI patients. We found that kallikrein activity, high molecular weight kininogen cleavage, and bradykinin levels— measures of contact system activation— were significantly elevated in MCI patient plasma compared to plasma from age- and education-matched healthy individuals. Changes were more pronounced in MCI patients with impaired short-term recall memory, indicating the possible role of the contact system in early cognitive changes.

Published: July 2020

One of the major challenges of medical sciences has been finding a reliable compound for the pharmacological treatment of Alzheimer’s disease (AD). As most of the drugs directed to a variety of targets have failed in finding a medical solution, natural products from Ayurvedic medicine or nutraceutical compounds emerge as a viable preventive therapeutics’ pathway. Considering that AD is a multifactorial disease, nutraceutical compounds offer the advantage of a multitarget approach, tagging different molecular sites in the human brain, as compared with the single-target activity of most of the drugs used for AD treatment. We review in-depth important medicinal plants that have been already investigated for therapeutic uses against AD, focusing on a diversity of pharmacological actions. These targets include inhibition of acetylcholinesterase, β-amyloid senile plaques, oxidation products, inflammatory pathways, specific brain receptors, etc., and pharmacological actions so diverse as anti-inflammatory, memory enhancement, nootropic effects, glutamate excitotoxicity, anti-depressants, and antioxidants. In addition, we also discuss the activity of nutraceutical compounds and phytopharmaceuticals formulae, mainly directed to tau protein aggregates mechanisms of action. These include compounds such as curcumin, resveratrol, epigallocatechin-3-gallate, morin, delphinidins, quercetin, luteolin, oleocanthal, and meganatural-az and other phytochemicals such as huperzine A, limonoids, azaphilones, and aged garlic extract. Finally, we revise the nutraceutical formulae BrainUp-10 composed of Andean shilajit and B-complex vitamins, with memory enhancement activity and the control of neuropsychiatric distress in AD patients. This integrated view on nutraceutical opens a new pathway for future investigations and clinical trials that are likely to render some results based on medical evidence.
