Objetivo: descrever a atuação do enfermeiro no atendimento às mulheres em situação de violência sexual a partir da literatura. Método: pesquisa bibliográfica na modalidade revisão integrativa da literatura, com busca dos estudos primários publicados entre 2015 a 2019, realizada em abril de 2020, em sete bases de dados, sendo selecionados e analisados 10 artigos. Resultados: da síntese das evidências, emergiram três categorias: assistência clínica medicamentosa, assistência clínica não-medicamentosa e falta de qualificação profissional, revelando insatisfação de algumas mulheres no atendimento. Conclusão: os estudos analisados descrevem com clareza a assistência de enfermagem prestada de imediato às mulheres pós agressão sexual, porém, não abordam a continuidade do processo, constituindo-se essa uma importante lacuna. A síntese de conhecimento produzido oferece subsídios valiosos para a melhoria da qualidade da assistência de enfermagem às mulheres em situação de violência e ratifica a importância dos seus resultados para fundamentar a prática clínica nesta área de estudo.

Objetivo: compreender a utilização dos registros de enfermagem na gerência do cuidado clínico-hospitalar. Método: estudo qualitativo, de caráter compreensivo, realizado em um hospital público de ensino de Minas Gerais, com 13 enfermeiras. Os dados foram coletados por entrevistas semiestruturadas, observação participante e pesquisa documental, entre outubro e novembro de 2017, e tratados pelo software IRaMuTeQ e análise de conteúdo. Protocolo de pesquisa aprovado pelo Comitê de Ética em Pesquisa da instituição. Resultados: após análise, emergiram três categorias: contexto de utilização dos registros e o desenvolvimento da gerência do cuidado; instrumentos adotados na elaboração dos registros; registros de enfermagem como meio de comunicação. Conclusão: os registros de enfermagem contribuem para o gerenciar e o cuidar, de maneira articulada. Entretanto, por meio da observação participante, constatou-se que os registros de enfermagem estavam associados apenas ao gerenciar, desvinculados do cuidar, o que dificulta a utilização destes como ferramenta de comunicação interprofissional e evidência da qualidade do cuidado.

Published: August 2021

Patients with end-stage renal disease (ESRD) have inferior outcomes after hip and knee total joint arthroplasty (TJA), with higher risk for surgical site complications (SSC) and periprosthetic joint infection (PJI). We conducted a systematic review and meta-analysis regarding outcomes after hip and knee TJA in ESRD patients who have received dialysis or a kidney transplant (KT) using PubMed, MEDLINE, Cochrane Reviews, and Embase in order to: (1) determine the mortality and infection rate of TJA in patients receiving dialysis or KT and (2) to identify risk factors associated with the outcome. We included 22 studies and 9384 patients (dialysis, n = 8921, KT, n = 463). The overall mortality rate was 14.9% and was slightly higher in KT patients (dialysis vs. KT, 13.8% vs. 15.8%). The overall SSC rate was 3.4%, while dialysis and KT patients each had an incidence of 3.3% and 3.6%, respectively. For PJI, the overall rate was 3.9%, while the incidence for dialysis patients was 4.0% and for KT patients was 3.7%. Using multi-regression analysis, age, sex, the type of arthroplasty (knee or hip) performed, and the form of renal replacement therapy (dialysis or KT) were not significant risk factors. In patients on dialysis or who had received a KT, TJA is associated with a slight increase in mortality, SSC and PJI rates.

Aspiration or arthrotomy for paediatric septic arthritis of the shoulder and elbow: a systematic review
Authors: Spaans Anne J. , Donders C.M. (Lilian) , Bessems J.H.J.M. (Gert) , van Bergen Christiaan J.A.
Published: August 2021

Upper extremity arthritis in children can be treated with joint aspiration, arthroscopy or arthrotomy, followed by antibiotics. The literature seems inconclusive with respect to the optimal drainage technique. Therefore, the objective of this systematic review was to identify the most effective drainage technique for septic arthritis of the upper extremity in children. Two independent investigators systematically searched the electronic MEDLINE, EMBASE and Cochrane databases for original articles that reported outcomes of aspiration, arthroscopy or arthrotomy for septic arthritis of the paediatric shoulder or elbow. Outcome parameters were clinical improvement, need for repetitive surgery or drainage, and complications. Out of 2428 articles, seven studies with a total of 171 patients treated by aspiration or arthrotomy were included in the systematic review. Five studies reported on shoulder septic arthritis, one study on elbow septic arthritis, and one study on both joints. All studies were retrospective, except for one randomized prospective study. No difference was found between type of treatment and radiological or clinical outcomes. Aspiration of the shoulder or elbow joint required an additional procedure in 44% of patients, while arthrotomy required 12% additional procedures. Conclusion: Both aspiration and arthrotomy can achieve good clinical results in children with septic arthritis of the shoulder or elbow joint. However, the scientific quality of the included studies is low. It seems that the first procedure can be aspiration and washout and start of intravenous antibiotics, knowing that aspiration may have a higher risk of additional drainage procedures.

Depixelation of coherent fiber bundle imaging by fiber-core-targeted
scanning
Authors: Li Qian , Rohringer Wolfgang , Preißer Stefan , Erkkilä Mikael T. , Haindl Richard , Sattmann Harald , Liu Mengyang , Fischer Balthasar , Leitgeb Rainer , Drexler Wolfgang
Published: August 2021

A novel fast proximal scanning method, to the best of our knowledge,
termed fiber-core-targeted scanning (FCTS), is proposed for
illuminating individual fiber cores sequentially to remove the
pixelation effect in fiber bundle (FB) imaging. FCTS is based on a
galvanometer scanning system. Through a dynamic control of the scan
trajectory and speed using the prior knowledge of fiber core
positions, FCTS experimentally verifies a precise sequential delivery
of laser pulses into fiber cores at a maximal speed of 45,000 cores
per second. By applying FCTS on a FB-based photoacoustic
forward-imaging probe, the results demonstrate that FCTS eliminates
the pixelation effect and improves the imaging quality.
Uniformity improvement on received optical power for an indoor visible light communication system with an angle diversity receiver
Authors: Chi Sihui , Wang Ping , Niu Shuqiang , Che Hui , Wang Zhao , Wu Yiran
Published: August 2021

In this work, an angle diversity receiver (ADR) structure is proposed to optimize the uniformity of the received optical power distribution in an indoor visible light communication (VLC) system. Taking the rectangular and hybrid layouts with 16 light-emitting diodes as examples, different inclination angles and the number of side detectors are investigated with three diversity combining techniques in a typical room, where the primary reflection of the wall is considered. Simulation results showed that the inclination angles and the number of side detectors would affect the variance and average of the received optical power, and the variance would decrease with the increase of the number of side detectors. In addition, maximal ratio combining is more suitable for the ADR when the variance and average of the received optical power are considered simultaneously. By applying the ADR with five side detectors, the variances of the received optical power will decrease by 81.34% and 86.09% under the rectangle layout and the hybrid layout, respectively. This work will benefit the design and development of the VLC system.
High-resolution micro-optical accelerometer with an electromagnetic driver: design and analysis
Authors: Gao Shan , Zhou Zhen , Huang Zhuang , Feng Lishuang
Published: August 2021

Optical displacement detection is widely used in various micro-electro-mechanical system (MEMS) sensors because of its high sensitivity. The optical accelerometer has a high theoretical resolution. However, due to the small working range of optical detection, the open-loop measuring range of a high-resolution optical accelerometer is usually only tens to hundreds of milligrams. To increase the measurement range, we propose a high-resolution micro-optical accelerometer with electromagnetic force feedback. The optical principle, mechanical structure, and manufacturing process are analyzed. The accelerometer is predicted to work in the first modal with displacement sensitivity at 2.56 µm/g, corresponding to 0th diffraction beam optical sensitivity 1.93%/nm. The designed electromagnetic driver can increase the acceleration measurement range from 0.012 to

. These results provide a theoretical basis for the design and fabrication of a high-resolution micro-optical accelerometer with an electromagnetic driver. The electromagnetic drive scheme introduced effectively improves the dynamic range of high-precision optical accelerometers and can be applied to other optical MEMS sensors.
Ge2Sb2Te5-based reconfigurable metasurface for polarization-insensitive, full-azimuth, and switchable cloaking

Electromagnetic (EM) metasurface mantles afford an alternative avenue, allowing for the possibility of rendering arbitrary-shape objects unobservable. But the available mechanisms either depend on the states of polarization or the azimuth of wave incidence, or cannot dynamically manipulate cloaking responses without altering the structures. Herein, a three-dimensional closed-ring-based metasurface carpet cloak involving

By judiciously designing meta-atoms on the external surface of a spherical object, the scattered wavefront, including the distributions of EM fields and polarizations, can be reconstructed, resembling what is deflected from a flat plane. Enabled by the perfectly symmetric distribution of meta-atoms, the carpet cloak is demonstrated to work well under arbitrary states of polarization and arbitrary azimuthal angles of incident light. Meanwhile, by converting

Analysis of lens fracture in precision glass molding with the finite element method
Authors: Liu Yue , Xing Yintian , Li Chuang , Yang Chao , Xue Changxi
Published: August 2021

Precision glass molding (PGM) technology has recently emerged as a promising fabrication method for mass-fabricating optical glass lenses with complex surfaces. However, lens fracture as a common problem has not been analyzed in detail. In this paper, the divergent cone cracks in the molded lens were analyzed using the finite element method, because crack propagation cannot be seen in the molding process. A three-dimensional model was established in MSC Marc software for analyzing the temperature, stress components, and principal stress of the glass in different molding stages. The crack paths were analyzed using the simulation results and the fracture basis. Based on the analysis, PGM experiments with different processing parameters were carried out. The appearance of the molded lenses demonstrated the rationality and correctness of the analysis. Thus, analyses of other types of lens fractures can use the analysis method proposed in this paper rather than relying on trial and error.
Active terahertz metamaterials electrically modulated by InGaZnO Schottky diodes

Published: August 2021

Active metamaterials (MTMs) are artificially engineered structures with tunable and exceptional properties that are absent in natural materials. Recently, InGaZnO (IGZO), a widely used semiconductor for large-area and flexible display backplane drivers, has gained interest for active control of MTMs due to its large-area uniformity, ease of thin film deposition, and low cost. In this paper, IGZO Schottky barrier diodes (SBDs) are proposed to reconfigure electric-field-coupled inductor-capacitor (ELC) MTMs and actively control terahertz (THz) waves for the first time. The SBDs are designed to bridge the capacitors of the ELC resonators so that the average conductivity within the capacitor gap can be modulated by bias voltage while keeping the capacitance value almost unchanged. To precisely simulate this mechanism, two U-shaped resistive sheet models beside the gap are built for IGZO SBD in 3-D simulation for maintaining the same capacitance and resonant frequency. Furthermore, a device with 14400 MTM cells is fabricated and characterized using frequency-domain spectroscopy. The measured transmission shows a continuous modulation from -14.2 to -9.4 dB at 0.39 THz, which corresponds to a modulation depth of 14.3%. This work paves a new way for active THz MTMs using industrial compatible thin-film technology.
Unique prospects of phase change material Sb2Se3 for ultra-compact reconfigurable nanophotonic devices
Authors: Jia Wei , Menon Rajesh , Sensale-Rodriguez Berardi
Published: August 2021

In this work, we explore inverse designed reconfigurable digital metamaterial structures based on phase change material Sb2Se3 for efficient and compact integrated nanophotonics. An exemplary design of a 1 × 2 optical switch consisting of a 3 µm x 3 µm pixelated domain is demonstrated. We show that: (i) direct optimization of a domain containing only Si and Sb2Se3 pixels does not lead to a high extinction ratio between output ports in the amorphous state, which is owed to the small index contrast between Si and Sb2Se3 in such a state. As a result, (ii) topology optimization, e.g., the addition of air pixels, is required to provide an initial asymmetry that aids the amorphous state's response. Furthermore, (iii) the combination of low loss and high refractive index change in Sb2Se3, which is unique among all phase change materials in the telecommunications 1550 nm band, translates into an excellent projected performance; the optimized device structure exhibits a low insertion loss (∼1.5 dB) and high extinction ratio (>18 dB) for both phase states.
Rectangular single-mode polymer optical fiber for femtosecond laser inscription of FBGs
Authors: Dash Jitendra Narayan , Cheng Xin , Gunawardena Dinusha Serandi , Tam Hwa-Yaw
Published: August 2021

In this study, a novel rectangular polymer single-mode optical fiber for femtosecond (fs) laser-inscribed fiber Bragg gratings (FBGs) is proposed and demonstrated. The cylindrical geometry of the widely used circular fiber elongates the fs laser beam along the fiber axis, resulting in reduced laser intensity and requiring index-matching oil immersion during FBG inscription. However, the flat geometry and negligible surface roughness of the featured fiber significantly diminish this lensing distortion and eliminate the need for oil immersion, thereby resulting in optimal focusing of the laser beam, permitting direct and efficient inscription of FBGs within the optical fiber. The core and cladding of the rectangular fiber were fabricated using two different grades of ZEONEX, a cyclo olefin polymer, which have slightly different refractive indices. The similar glass transition temperature for core and cladding simplifies the fiber drawing process, and a rectangular single-mode optical fiber with dimensions of

and core diameter of 9.4 μm was fabricated using an in-house fiber drawing facility. A second harmonic (520 nm) fs laser beam was used to successfully inscribe a 2-mm-long FBG in the rectangular fiber within a few seconds with a point-by-point technique. The inscription of a single FBG leads to the excitation of higher order FBG peaks at 866.8 and 1511.3 nm, corresponding to widely used wavelength bands in fiber optic sensing. The strain and temperature sensitivities of the FBG were measured to be

Published: August 2021

The fashion industry’s heightened focus on sustainable production has enhanced the emergence of varied eco-conscious procedures such as re-upcycling. Nonetheless, the multiple steps required for such procedures often lead to more expensive products, consequently lowering consumers’ motivation to purchase such products. Do-it-yourself (DIY) fashion videos can motivate individuals to try DIY fashion, while promoting sustainable production and consumption of clothing. This study tested if DIY fashion videos could be used to change the perception among Thai youth on the DIY sustainable fashion. An Instagram profile named ‘Broke Vogue’ was created and it shared a variety of DIY fashion-related contents and activities. The page gained 300 followers during the six weeks it was active. The profile also invited participants to take a survey to evaluate their attitudes towards DIY fashion. This served as the data source of this study. The majority of participants in the survey were university students (N = 102, 73.5 per cent women). The results confirmed that participants developed a positive opinion concerning DIY fashion after visiting the page. However, it also strengthened some negative stereotypes as participants were more confident that DIY fashion was not appropriate for senior citizens or citizens with financial issues.
The homeland and the city: Rural and urban decolonization in Patricia Grace’s Potiki
Authors: Brückner Pia
Published: August 2021

Over the last decade, studies from multiple academic disciplines have started to examine the city’s role as a place of decolonization for Māori people in Aotearoa New Zealand. This article uses those multidisciplinary findings as a basis for literary criticism by re-examining the role of the city in Patricia Grace’s second novel Potiki (1986). Indigenous urbanites are generally deemed impossible and ‘unnatural’ within the inherited colonial ideology. And even though the novel foregrounds a Māori family’s return to their ancestral land, this article argues that the very success of this return is based on the interrelation between ‘rural’ and ‘urban’ strategies of decolonization. While the colonial urban–rural binary often seems reinforced, the novel inverts the power positions between colonizer and colonized, thereby promoting decolonization. At the same time, some characters become unconsciously entrapped in a romanticized pre-migration idyll, which the harsh reality of agricultural working life cannot satisfy. In order to assess the effectiveness of the different decolonizing strategies employed by the characters, my analysis utilizes the postcolonial key concepts of binary opposition, the liminal, the interstice, ambivalence, double consciousness and cultural appropriation, and examines the degree to which inherited binary oppositions are either maintained or defied by Pākehā and Māori within the novel.
Vā at the time of COVID-19: When an aspect of research unexpectedly turns into lived experience and practice

Published: August 2021

In 2019, the Vā Moana–Pacific Spaces research group at Auckland University of Technology (AUT) began to investigate how core Moana and Māori values can be translated from onsite, embodied engagements into digital environments. This was prompted by our wish to provide access to all those who could not travel to attend a conference in late 2021 for our Marsden-funded research project, ‘Vā Moana: Space and relationality in Pacific thought and identity’ (2019–22). The onset of the COVID-19 pandemic fundamentally reframed this premise, as providing offsite access was no longer simply a ‘nice option’. The crisis challenged us to find out how virtual participation in events can uphold values of tikanga (correct procedure, custom) and teu le vā (nurturing relational space). In particular, our research examines practices foregrounding vā as the attachment to and feeling for place, as well as relatedness between people and other entities. We have observed an emerging conceptual deployment of vā as relational space and a mode of belonging, especially in diasporic constellations oriented by a cosmopolitan understanding of vā. Due to this focus, we noticed early on that simply moving meetings online is unlikely to create a supportive environment for Indigenous researchers in diaspora, who share principal values and a commitment to a kaupapa (agenda, initiative). This realization led us to interrogate how research collaboration and circulation are influenced by the distinct features of physical and online contexts, protocols and connectivity. To develop the alternative kind of vā we envisaged – together with strategies to sustain it through our online practices – thus became a much larger project in the times of rapid change under COVID-19. This is a very brief, initial report on our experiences.

Natural fibres such as Banana (B), Jute (J) and Kenaf (K) were hybridized in different stacking sequences in vinyl ester. The composites with hybridized fibres were tested to evaluate their tensile, flexural and impact properties. Further, they were also tested for their water absorption and thickness swelling behavior. The hybridization of the fibre mats had an encouraging outcome on the mechanical behavior. The JKBKBJ hybrid composite possessed the maximum tensile strength (34.12 MPa) while maximum stiffness of 1.667 GPa was observed for the KBJJBK hybrid composites. The observations from the flexural testing indicated that the hybrid composites resisted the flexural load for higher displacement. All the hybrid configurations presented better impact strength over the composites reinforced with kenaf and jute fibres. Among the hybrid composites investigated, the KJBBJK hybrid composite displayed highest impact strength (12.32 kJ/m2). The improved strength, stiffness and lower moisture absorption properties make the composites with hybridized fibres a potential candidate for the light weight structural applications.

Nüfus artışı, tarım alanlarının yetersizliği ve iklim değişiklikleri gibi sorunlar nedeniyle, gıda kaynaklarının sürdürülebilirliği giderek önem kazanmaktadır. Gelecekte özellikle protein gereksiniminin karşılanması temel bir sorun olarak öngörülmektedir. Yenilebilir böcekler geleneksel protein kaynakları ile kıyaslandığında üretimlerindeki avantajlar nedeniyle sürdürülebilir gıda kaynakları olarak değerlendirilmektedir. Güney Amerika ülkeleri ve Çin gibi ülkelerde geleneksel olarak tüketilen ancak batı toplumlarında neofobi ve tiksinme nedeniyle kabul görmezken bütün formu yerine un formunda kullanılması entomofajiyi uygulamak için umut verici bir seçenek olarak görülmektedir. Yenilebilir böceklerin, besleyici özellikleri ile antidiyabetik ve antimikrobiyel gibi potansiyel etkileriyle sağlık üzerine faydalarının incelendiği çalışmalar artmaktayken toksik ve alerjik etkileri üzerine çalışmalar halen yetersizdir.

Published: August 2021

Why and how did the International Labor Organization and the military junta of Myanmar transform their relationship so dramatically, from confrontation to cooperation, between 2007 and 2010? What insights can be drawn from this case regarding the successful operation of an international organization in an authoritarian environment? By investigating the evolution of the military leadership’s perception, this article aims to demystify authoritarian decision-making and identify the interactive mechanisms operating between internal and external dynamics and between an authoritarian regime and an international organization. The qualitative fieldwork includes direct interviews with former top military government leaders, who provide valuable insights into the decision-making logic at the highest level.
A Securitized “One Country, Two Systems”?
Authors: Meng U Ieong , Xiangning Wu
Published: August 2021

This paper examines how Macau, with a different political and legal system under the “one country, two systems” principle, fits into China’s securitization and what impact that has on its local governance. We argue that in recent years Macau’s legal system has gradually transformed into a means of social control. Through case files related to the Assembly and Demonstration Law drawn from the Court of Final Appeal, we demonstrate that although Macau is unlike Hong Kong, where dissidents are subject to severe repression, Beijing’s emphasis on national security has weakened the checks-and-balances function of Macau’s legal system and substantially narrowed the scope of freedom of speech, even though it is nominally guaranteed and protected by the Basic Law.
Effects of montmorillonite nanoclay on the properties of chemimechanical pulping paper
Authors: Kasmani Jafar Ebrahimpour , Samariha Ahmad
Published: August 2021

The effects of nanoclay were studied relative to the physical, mechanical, optical, and morphological properties of chemimechanical pulping papers. Nanoclay was incorporated at 0%, 2%, 4%, 6%, 8%, or 10%. To increase the retention, 1% cationic starch was used in all test papers. Handsheets (60 g/m2 in weight) were tested to determine their physical, mechanical, optical, and morphological properties. Up to 2% nanoclay increased the tensile strength; at values greater than 2%, the tensile strength decreased. The addition of up to 4% nanoclay increased roughness; between 4% and 10% nanoclay, roughness decreased. With 10% nanoclay, the tear strength, burst strength, and brightness decreased, but the air resistance, opacity, and yellowness increased. Scanning electron microscopy showed that the nanoclay filled the pore spaces between fibers, thus increasing air resistance. X-ray diffraction patterns indicated an intercalated structure.

Prediction of actual limit stresses in a thin-walled pipe loaded with internal pressure and axial tension
Authors: Kozbur Halyna , Shkodzinsky Oleh , Yasniy Oleh , Kozbur Ihor , Hrom'yak Roman
Published: August 2021

If a thin-walled pipe loaded with internal pressure and tension allows the appearance of plastic trains, then the uniform plastic stability loss with the emergence of a local plastic deformation zone is considered the limit state, the corresponding stresses are considered as the limit. Correct prediction of the stress-strain state at the moment of strain localization requires taking into account the actual size of the loaded pipe and the calculation of true stresses. The article proposes the implementation of the method of predicting the limit values of true stresses that appear in the pipe at different ratios of internal pressure and axial tension. The physical and mechanical properties of the material, the type of stress state and the change in the actual dimensions of the loaded element are taken into account.

In the framework of the model of locally inhomogeneous electrically conductive nonferromagnetic solid, the near-surface inhomogeneity in a solid cylinder is investigated. It is shown that such inhomogeneity is characterized by three characteristic sizes associated with the structural inhomogeneity of the material, the roughness of the real surface and the electronic subsystem. The charge distribution features a double electric layer. The size effect of fiber strength and its dependence on geometric inhomogeneity parameters of the surface are studied.

The diffusion of an admixture substance in a multiphase layer with randomly disposed spherical inclusions was investigated. The solution of the initial contact-boundary value problem is obtained in the form of the integral Neumann series. Computer simulation was performed based on the obtained calculation formula. Main regularities of the distributions of the averaged admixture concentration in the layer depending on the values of the diffusion coefficients, density and volume fractions of inclusions were established. The influence of the number of phases of the porous body on the diffusion processes in a multiphase layer with a uniform distribution of spherical inclusions was determined. The dependence of the increase of the averaged concentration function on the characteristic radii of spherical inclusions was analyzed, in particular, it is shown that the behavior of this function does not depend on the ratios of the reduced diffusion coefficients.

We consider use of ontological background knowledge in intelligent information systems and analyze directions of their reduction in compliance with specifics of particular user task. Such reduction is aimed at simplification of knowledge processing without loss of significant information. We propose methods of generation of task thesauri based on domain ontology that contain such subset of ontological concepts and relations that can be used in task solving. Combinatorial optimization is used for minimization of task thesaurus. In this approach, semantic similarity estimates are used for determination of concept significance for user task. Some practical examples of optimized thesauri application for semantic retrieval and competence analysis demonstrate efficiency of proposed approach.

The tasks of modelling and the components of the basic model of applied task protection of a distributed information system have been considered. The measurement and relationship of security parameters, protection, new and reference attacks, anomalies, and threat environments have been proposed. The conditions of threats, attacks and, consequently, inconsistencies in the results of applied tasks are proved. At the beginning of the article the concept of a distributed information system, system of applied tasks, modern trends of zero-trust architecture in building information security systems are discussed. Further, it gives an overview of existing methods of detection and counteraction to attacks based on reference knowledge bases. To improve the level of security it is proposed to analyze the causes of attacks, namely hazards and threats to the system. Attacks, hazards and threats are considered as structured processes that affect the internal and external environment of the system of the applied tasks with a further impact on the output of these tasks. The concepts of security level and security level of a distributed information system are introduced, as well as the concepts of applied task, environment, and user contradictions. As the logical metrics of discrepancy detection the apparatus of semantic analysis is proposed, which (based on the reference knowledge base, the apparatus of text transformations) should be applied at the stage of loading of applied task and describe the input and output data, requirements to the environment of the task solution. The result of the research is the proposed method for identifying additional data about hazards, threats, attacks, countermeasures to attacks, applied task-solving. This data is generated from the reference and augmented textual descriptions derived from the proposed contradictions. By building additional reference images of threats, attacks, countermeasures, it becomes possible to prevent the activation of new attacks on the distributed information system.

It is becoming clear with growing complication of cybersecurity threats, that one of the most important resources to combat cyberattacks is the processing of large amounts of data in the cyber environment. In order to process a huge amount of data and to make decisions, there is a need to automate the tasks of searching, selecting and interpreting Big Data to solve operational information security problems. Big data analytics is complemented by semantic technology, can improve cybersecurity, and allows you to process and interpret large amounts of information in the cyber environment. Using of semantic modeling methods in Big Data analytics is necessary for the selection and combination of heterogeneous Big Data sources, recognition of the patterns of network attacks and other cyber threats, which must occur quickly to implement countermeasures. Therefore to analyze Big Data metadata, the authors propose pre-processing of metadata at the semantic level. As analysis tools, it is proposed to create a thesaurus of the problem based on the domain ontology, which should provide a terminological basis for the integration of ontologies of different levels. To build a thesaurus of the problem, it is proposed to use the standards of open information resources, dictionaries, encyclopedias. The development of an ontology hierarchy formalizes the relationships between data elements that will be used in future for machine learning and artificial intelligence algorithms to adapt to changes in the environment, which in turn will increase the efficiency of big data analytics for the cybersecurity domain.

Modern workloads, parallel or sequential, usually suffer from insufficient memory and computing performance. Common trends to improve workload performance include the utilizations of complex functional units or coprocessors, which are able not only to provide accelerated computations but also independently fetch data from memory generating complex address patterns, with or without support of control flow operations. Such coprocessors usually are not adopted by optimizing compilers and should be utilized by special application interfaces by hand. On the other hand, memory bottlenecks may be avoided with proper use of processor prefetch capabilities which load necessary data ahead of actual utilization time, and the prefetch is also adopted only for simple cases making programmers to do it usually by hand. As workloads are fast migrating to embedded applications a problem raises how to utilize all hardware capabilities for speeding up workload at moderate efforts. This requires precise analysis of memory access patterns at program run time and marking hot spots where the vast amount of memory accesses is issued. Precise memory access model can be analyzed via simulators, for example Valgrind, which is capable to run really big workload, for example neural network inference in reasonable time. But simulators and hardware performance analyzers fail to separate the full amount of memory references and cache misses per particular modules as it requires the analysis of program call graph. We are extending Valgrind tool cache simulator, which allows to account memory accesses per software modules and render realistic distribution of hot spot in a program. Additionally the analysis of address sequences in the simulator allows to recover array access patterns and propose effective prefetching schemes. Motivating samples are provided to illustrate the use of Valgrind tool.

As the amount of media content increases, there is a need for its automated sounding with the most accessible built-in and mobile means. The factors influencing the formation of different intonations were analyzed in the article, the dependences of the change of sound characteristics in accordance with the intonations were mathematically described. In the course of the study, the numerical analysis of sentences was improved using the moving average method for smoothing audio recording, approximation lines for approximate generalization of emotions as mathematical functions, and Fourier transform for volume control. The obtained dependences allow to synthesize the necessary intonations according to the punctuation of the sentence, the presence of emotionally colored vocabulary and psycho-emotional mood of the speaker when reading such a text. As a result of our study, software for emotional sounding of texts was developed, which provides the perception of audio information easier, clearer and more comfortable based on the use of built-in processors of mobile devices.

The study of the nesting birds of the coastal riparian zones in Great Kabylia in Algeria, allowed us to identify 45 species of birds, belonging to 12 orders and 26 families. The richest site in terms of species is Takdempt (31 species). The lowest diversity is noted at the level of Boudouaou wadi with 16 species. The values of the Shannon-Weaver diversity index (H') for all sites are quite high (≥3 bits). Concerning the global abundance of avifauna, the site that represents the highest centesimal frequency is that of Takdempt (20.87 %) and this is due to the presence of a colony of Bubulcus ibis (Linnaeus, 1758). The bird communities of the sampled sites are not identical, but the degree of similarity, in general, is quite high (≥ 50 %). The main factors controlling the diversity and the structure of the avifauna of Great Kabylia coastal riparian zones are represented by vertical and horizontal vegetation structure
