Published: December 2022

The main object of the study is to consider the binomial transform for quadra Fibona-Pell sequence and quadra Fibona-Pell quaternion. In the paper, which consists of two parts in terms of the results found, the first step was taken for the sequence by defining the binomial transform for the quadra Fibona-Pell sequence in the first part and then finding the recurrence relation of this new binomial transform. Then, the Binet formula, generating function and various sum formulas of the sequence were found. In the second part, the binomial transform is applied for the quadra Fibona-Pell quaternion, which was discussed in a thesis before. Similar results in the first section are covered in the quaternion binomial transform.
FIRST INVESTIGATIONS OF DAMAGE TO BUILDINGS AND STRUCTURES AS A CONSEQUENCE OF COMBAT ACTIONS
Authors: NUZHNY Valery
Published: December 2022

On February 24, 2022, a large-scale invasion of the troops of the Russian Federation on the territory of Ukraine took place. In particular, active hostilities took place on the territory of Kyiv region within the boundaries of the settlements and surrounding them Borodyanka, Makariv, Gostomel, Irpin, Bucha, Vorzel, etc.
The result was the destruction and damage of a large number of buildings and structures, which suffered shock-explosive and fire damage, not typical for operation in peacetime conditions. It is also necessary to distinguish between direct damage to structures from the impact of ammunition (missiles, shells, mortar mines, large-caliber bullets, etc.) and secondary damage from the action of an explosive air wave. Destruction in places has a large-scale and systemic nature, when, for example, as a result of fire and temperature deformations during heating, cracks develop on the walls in other areas.
There are also hidden defects, when, for example, internal delamination of brickwork occurs due to impacts. Since state institutions and units of the State Emergency Service did not work in populated areas that were under occupation, the fires did not go out and this led to the deepening of their consequences. For the first time after the de-occupation of the northern regions of Ukraine, the problem of restoring buildings and structures of both critical infrastructure and housing arose, and this problem is relevant during the subsequent liberation of other regions of Ukraine from occupation.
From April until now, works on conducting surveys of buildings and structures in accordance with the accepted methods and regulations of the Ministry of Regional Building of Ukraine have been ongoing. Although in fact each case is unique, certain regularities can be found in determining the nature of damage and their classification for the purpose of choosing methods of strengthening and repairing structures.
 In many ways, the quality of the assessment depends on the experience of the expert and the design engineer performing the survey. Thus, in the first months, when surveys were conducted by leading organizations, including state research institutes, conclusions were given about the partial dismantling of buildings and structures, which, when alternative surveys were conducted, turned out to be hasty and erroneous.

Authors: ADAMENKO Viacheslav
Published: December 2022

From the analysis of the principles and methods of designing the world-famous Eiffel Tower, which at the time of its construction was the tallest tower in the world (312.12 m), and the National Stadium of Singapore sports hub, which is the largest steel dome in the world (diameter 310 m), the transformation of approaches to calculation and detailing of steel buildings was followed.
Based on the architectural, structural, organizational, technological and economic parts of the original project of the Eiffel Tower, the process of its design and construction is considered in detail. It is shown that the design and construction of the tower was carried out with thorough theoretical preparation, extensive use of mathematical apparatus, manual calculations of all parts of the project, the use of railways, steam cranes and industrial production of parts of steel structures.
The sequence of project development and construction of the dome of the National Stadium of Singapore sports hub was analyzed, with the creation of a 3D parametric model, calculations using the finite element method, computer optimization of the shape and size of structural parts, programming of special modules and development of algorithms to ensure the compatible operation of various software complexes, and design, detailing, development of drawings, as well as the transfer of all necessary information to the metal construction plant, for their production on CNC machines, using 3D BIM information systems.
It was concluded that thanks to the development of information technologies, there was a transition from manual execution to the predominant use of computer methods of calculation and detailing of steel buildings.
Ways to improve the further development of methods and approaches to the calculation and detailing of steel buildings are proposed.

Authors: MARTYNIUK Ivan
Published: December 2022

One of the main and responsible stages of creating an apparatus for numerical analysis of structures using the finite element method is its implementation in the form of a set of programs. The principles of complex construction should take into account modern requirements for strength calculation software in modern calculation complexes. Among them, first of all, automation of the main stages of the computing process, rational use of the resources of the operating and external memory of storage devices, non-closedness in relation to the classes of problems to be solved, algorithms for the task of input data, the method of discretization and solution of systems of equations and etc. In addition, the structure of the programs should take into account the specifics of the semi-analytical method of finite elements, for which such a large experience of creating developed systems of mathematical support for the search of spatial structures has not yet been accumulated, as when using the traditional version of FEM. Considerable experience in solving finite element mechanics problems, accumulated over the past decades, has been reflected in a number of industrial commercial software complexes of domestic (LIRA, SCAD) and foreign (ANSYS, Nastran, ABAQUS) production. The developed finite element base of these software complexes allows you to obtain solutions to a wide range of problems of the mechanics of a deformable rigid body for objects of different dimensions, including for massive spatial bodies, and convenient means of input-output of information and processing of the obtained results make them very accessible to a wide circles of users and allow to display the obtained results with the maximum degree of visibility. There are also object-oriented complexes created at manufacturing enterprises and research institutes, for example at the Institute of Strength Problems of the National Academy of Sciences of Ukraine, at the Dnipropetrovsk National University.
The conducted research will determine the most optimal ways of solving the listed problems from the point of view of computing costs and complexity of implementation, as well as outline the circle of unsolved issues.

Published: December 2022

The main processes necessary for the development of microstructure and hydration of concrete and their composites for use in structures with high durability, frost resistance, water resistance are analyzed. The potential development that will ensure the strength of concrete and their composites, which have been modified by a complex of fine additives in the time range up to 365 days, has been determined. The experimental formulation of the concrete mixture, which was modified by a complex of fine modifiers based on microsilica (MK) and metakaolin (MTK), was used for testing. Concrete mixing technology has also been improved. The structure of ultra-high-strength concrete is formed during physicochemical reactions, which are accompanied by the binding of free water with clinker minerals, the formation of a saturated solution of crystal hydrates and their subsequent crystallization. Determining compounds of cement structure are such hydration products as: calcium silicate hydrate with various modifications, portland, calcite. For a more complete picture of the formation of hydration phases in high-strength concrete composites and the effect of ultrafine modifiers, the microstructure of fracture surfaces and their phase composition on the 28-day aging of concrete composites were studied by scanning electron microscopy and energy-dispersive X-wave spectroscopy.

Comparative microanalysis and elemental analysis of various concrete composites of high structural strength and density using the methods of X-ray diffraction and energy-dispersive X-wave spectroscopy. However, the presence of Al in the later stages of hydration can also lead to the formation of secondary phases. The molar ratio of CaO to SiO2 in C-S-H is one of the main parameters for determining and controlling the properties of the calcium hydrosilicate system, which can be used to characterize some parameters of concrete durability. The structure of concrete is actually the main factor that determines its mechanical properties and their security throughout the life of the structure. Regularities of formation of structure and properties are common to all types of concrete.

Published: December 2022

The article considers the numerical study of multicriteria optimization of the minimum surface of a shell on rectangular contour taking into account the thermal load. The authors showed the theoretical formulation of multicriteria parametric optimization. Using of thermal force load is very important for objects that have a large span, especially using the static and temperature load in one place of a shell. This makes it possible to cover a wider range of construction site operation. In structural mechanics, there are three main types of standard shells of minimum surface: shape optimization, parametric optimization, and topological optimization. The article simultaneously combines two studies on the same object: shape optimization and parametric. The method of constructing this minimal surface on a rectangular contour is described. The specifics of the issuance of thermal power load in the optimization calculation, which is in all initial indicators and coefficients. The types of work of target functions are shown, namely: under what conditions they conflict, under what conditions they consolidate, under what conditions they are independent of each other. The numerical study uses the author's software, which allows in automatic mode a multicriteria optimization calculation with target functions - weight and Mises stress, design variables - thickness from 1 to 200 mm, presented as a Mises voltage of 240 MPa. The result showed that the target functions of the conflict change, but the weight decreases by 15%, and move along the coordination axes by 80% of the elements. After determining the displacements and stresses according to Mises, the process of designing and selecting the section of the structure for construction begins. The stage of design makes it possible to save material and redistribute it to the desired zones. From the graph of the change of objective functions according to the optimal height, what is the point for the objective functions - weight and move along the coordination axes is absence. The overall purpose of the study shows the possibility of using authoring software to use two types of optimization: optimization of shapes in the form of these minimum surface parameters on rectangular contour and multicriteria optimization together on the research subject, which is interesting and applied in structural mechanics.

Authors: Ivanchenko G.M , Kosheviy O.O. , Zhupanenko I.P.
Published: December 2022

Providing all parameters according to two groups of limit states at the design stage is a multi–criteria task. Optimal design helps to perform such tasks. When the phenomenon of resonance occurs, it is necessary to change the frequency of forced oscillations of the load–bearing structures of various tanks and coatings in order to ensure sufficient strength and stability of the structure and the building in general. For this purpose, there is a separate type of problem in optimal design that allows us to change the forced frequencies of oscillations using the example of the shell of the minimum surface on a rectangular contour.

In mathematical point of view, optimal design tasks are optimization tasks, finding the extremum of the target function (maximum or minimum). Methods of solving optimal design problems can be conditionally divided into two groups. One of them will include methods that are based on using necessary conditions for the extremum of the objective function. The second group includes methods: linear, convex and dynamic programming, random search methods. The application of modern methods of mathematical optimization requires powerful PCs with a large RAM, therefore, when choosing optimization, it is necessary to take into account the capabilities of computer equipment.

The optimization algorithm for single–criteria parametric optimization is performed as follows: the objective function is the weight of the shell of the minimum surface on a rectangular contour, the design variables are the shell thickness from 1 to 50 mm, the constraints are presented with first forced oscillation frequency is 0,15 Hz.

Using software complex Femap with Nastran and our own software, a single–criterion parametric optimization was made. The results of changing the objective function are reducing the weight of the shell by 2300 kg of C240 steel, which is equivalent to 10,3% without losing the strength and stability of the minimum surface shell on a rectangular contour. Using author's methodology and own software, it is possible to perform an effective optimization calculation for the minimum surface shell on a rectangular contour.

Published: December 2022

A significant range of organic and mineral binders produced by the industry allows for a wide variety of combinations, providing a variety of resulting compositions. This, in turn, makes it necessary to establish general regularities in the formation of their properties. An attempt is made in this article. The results of studies of the properties of concrete, which are a composition of Portland cement, fine aggregate and mineral–organic complex, intended for the creation of special structures. It is shown that the use of the organic component of the mineral–organic complex of micelle–forming surfactants or polyalcohols leads to the sealing of the inner surfaces of the pores that are formed in concrete, which leads to an increase in the strength of concrete. It has been proven that the most effective use of the mineral is as a mineral component of complex organic compounds containing so–called d–elements, such as iron. The currently widely used mineral–organic compositions of the first type are, as a rule, "mineral binder – organic polymer" or "mineral binder – bitumen (tar)" systems. These types of mineral–organic compositions have undergone quite serious tests and have been tested in operation and have not sufficiently confirmed their effectiveness. But, as you know, these types of organic materials have the disadvantage of aging, which is accompanied by depolymerization (polymer) or a change in structure (asphalts, tars). Therefore, the durability of this type of resistance is limited by the organic component of the mineral–organic composition. It is known that the adsorption properties of derivatives of higher fatty acids depends on the length of the hydrocarbon radical. This is due to the strength of attachment of derivatives of higher fatty acid to the mineral surface. This largely depends on the solubility of the compositions are formed. The solubility of these compounds is, in turn, is determined by the order of solubility of the corresponding salts higher fatty acids. The solubility of these compounds, in turn, determined by the solubility of the respective salts of fatty acids. the authors obtained a mineral–organic material which is a system of "mineral binder based on calcium – fatty acid – a substance containing iron". Mechanism of structure obtained mineral–organic material explained as follows. As is well known, are unsaturated higher fatty acids with two or more double bonds with oxygen independently oxidized.

Published: December 2022

The article researched and established that in order to improve the tools, models and methods of organizational-technological and geo-informational modeling of complex organizational training, the branch specifics of objects were taken into account, since cluster construction represents a variety of objects, and is also characterized by significant uncertainty of information support . At the same time, a significant amount of geoinformation, which is necessary for high-quality organizational and technological preparation of the territories allocated for construction, is not used. The work analyzes the main tasks and stages of complex organizational preparation of concentrated construction, existing technologies of automation of construction processes, to identify the technology of geoinformation modeling taking into account the specifics of the industry and the necessary tools for assessing the adequacy of the necessary information support.

The article describes the practical implementation of a geoinformation modeling tool for complex organizational preparation of concentrated construction for the development of a digital geoinformation 3D model of a consolidated plan of engineering networks based on the modern GEOCAD software complex of the GEOKAD company - a domestic developer of engineering GIS, which works in the AutoCAD 3D modeling environment. The researched experimental approbation of the methodology for assessing the reliability of the organizational preparation of the territorial cluster was carried out on the example of the development of the territorial cluster in the city of Vinnytsia, taking into account the possible states of the system and with the calculation of reliability indicators of consolidated calendar plans for the preparation of construction sites for the cluster objects. An analysis of the geoinformation provision of all cycles of organizational training was carried out and showed that in real practice there is no single system and comprehensive approach to both the formation of information provision and the functioning of the services of the customer-builder. In this connection, models of the functioning of the complex training system were considered and improved.

Communicative semantics in Lviv pop-jazz continuum: «Picardian third» and «Orpheus»
Authors: Kulyniak Mykhailo
Published: December 2022

The purpose of the work is to identify the specifics of the communicative semantics in the Lviv pop-jazz continuum on the example of the vocal octets «Picardian Third» and «Orpheus». The research methodology is based on the use of cultural and analytical methods, on the basis of the theoretical understanding of the communicative semantics concept and the extrapolation of the specified phenomenon to understanding the analysis of the specified creative collectives’ activities. The scientific novelty of the research: the article proposes a definition of the communicative semantics concept, which is interpreted as a set of meanings produced by one or another artistic centre in its multiple creative acts; the essence of the indicated semantics in the Lviv pop-jazz continuum is determined using the example of the octets «Picardian third» and «Orpheus». Conclusions. The specificity of the communicative semantics of creative collectives, whose activities are analysed in the article, demonstrates stylistic multiculturalism, while its nature is different in the two indicated octets. The semantics of the vocal formation «Picardian Third» from the point of view of pop-jazz communication is defined as a syncretism of national (folk, spiritual, and pop) and international jazz messages, when the essentially national repertoire is presented in jazz design. Instead, in the work of the «Orpheus» octet, we observe greater differentiation of the indicated messages; the communicative semantics of the collective is created in the process of simultaneous combination of various styles and approaches. At the same time, we can state that the activities of both octets harmoniously combine the tendencies of acculturation and inculturation, and this is a guarantee of the further harmonious development of multiple cultural processes associated with the specified collectives in the Lviv continuum and the European space, and also determines the prospects of future research into Lviv pop and jazz sphere.

Key words: communicative semantics, acculturation, inculturation, Lviv pop-jazz continuum, «Picardian third», «Orpheus».

Sources of Students’ Errors in EFL Writing in Indonesia
Authors: Hapsari Elsa Widya , Sudarman Sudarman , Utami Sri
Published: December 2022

The purpose of this review paper is to compile studies related to the sources of errors made by Indonesian students in a writing skill, to summarize some prior findings in order to provide updated literature on error analysis, to identify difficulties that Indonesian students face in an EFL writing context, and to investigate the factors that influence writing success and failure. The results showed that three major factors contribute to students' errors in EFL writing in Indonesia: the influence of the first language on writing, large class sizes, and a lack of writing practice. This is reasonable, as studies have demonstrated that despite years spent in school learning English, a significant number of errors can still be found in writing products composed by university students. Therefore, the teacher can use several strategies, including implementing a specific learning strategy that affects the target language, reducing the number of students in the class so that they have enough time to practice writing based on the writing process, and providing better instruction in the structure and grammar sections. Furthermore, teachers should spend more time and effort outside of the classroom to help students receive feedback, particularly through conferencing.
Direct Calculation of Band-Pass Filters
Authors: Chervinskiy E. N.
Published: December 2022

Introduction. When calculating band-pass filters (BPF), the circuit elements can be determined by converting the parameters of prototype low-pass filters (LPF). In a number of cases, the synthesized BPF does not have a direct prototype in the low-frequency range. Such filters include, e.g., BPFs with nodes tied to zero potential and other types of filters. Filters can be calculated directly by equating the coefficients of the synthesized filter transfer function (TF) and the realized TF obtained from the low-pass filter TF by the frequency conversion followed by solving the corresponding system of equations.

Aim. To develop a methodology for direct calculation of band-pass filters with attenuation poles.

Materials and methods. The simplest scheme of BPF with attenuation poles can be formed by two sequentially connected Г-shaped half-links on parallel circuits. Such a filter is realized only at certain requirements upon attenuation characteristics. When switching to BPF schemes with an additional parallel circuit in the transverse branch and a sequential circuit in the longitudinal branch, these restrictions are removed. In this paper, we develop a method for calculating inverse and quasi-elliptical BPF of П-shaped and T-shaped type, which have no restrictions when selecting the minimum attenuation and unevenness of the amplitude-frequency response (AFR).

Results. The TF analytical expressions of the 6th and 10th order BPF were derived. Relations were obtained that allow the number of equations of the system for determining the filter parameters to be reduced. For П- and T-shaped 6th order BPFs, representations of circuit inductances through the central frequency and filter capacitances were obtained. This made it possible to express transfer functions through capacitances, at the same time as reducing the number of equations of the system. Examples of direct calculation of the 6th and 10th order PPFs were given.

Conclusion. When converting TF of LPF, the frequencies of the realized AFR at both sides of the central BPF frequency are connected by certain relations. This fact makes it possible to eliminate the equations of the system that equate the coefficients of transfer function numerators, thereby reducing the total number of equations. Parameters, whose number exceeds that of the equations of the system, are selected arbitrarily from a number of standardized values. As a result, the accuracy of reproducing the realized frequency response is significantly improved.

Araştırma okul çağındaki çocukların COVID-19 hakkındaki resimlerinin 7, 10 ve 13 yaş gruplarına göre incelenmesi amacıyla yapılmıştır. Araştırmada hem nicel hem de nitel araştırma yöntemleri bir arada kullanılmıştır. Araştırmanın temel veri toplama aracı çocuklar tarafından çizilen COVID-19 resimleridir. Çalışma grubunu 7, 10 ve 13 yaşlarında olan 60 çocuk oluşturmaktadır. Her yaş grubundan 20 çocuk ile çalışma gerçekleştirilmiştir. Araştırmanın nitel bölümünde çocuklar tarafından yapılan resimler incelenmiştir. Çocuk resimleri içerik analizi yöntemi kullanılarak analiz edilmiştir. Çocuk resimlerinde insan, mekân/ortam, aktivite, sağlık, temizlik malzemeleri, doğa, renk ve diğer olmak üzere 7 tema 48 alt tema belirlenmiştir. Araştırmanın nicel bölümünde resimlerden elde edilen tema ve kodlar arasında fark olup olmadığını belirlemek için Kruskal-Wallis testi yapılmıştır. Araştırma sonucunda yaşlara göre çocuk resimlerinde mekân/ortam, doğa ve renk temasında gruplar arasında anlamlı bir farklılık olduğu, diğer temalarda ise anlamlı bir farklılık olmadığı belirlenmiştir. Hangi gruplar arasında anlamlı farklılık olduğunu belirleyebilmek için yapılan analiz sonucunda mekân/ortam temasında tüm yaş gruplarının birbirleri arasında anlamlı farklılık olduğu, doğa ve renk temasında ise 10 yaş grubu ile 7 ve 13 yaş grupları arasında fark olduğu belirlenmiştir. Her yaştan kişiyi olduğunu gibi pandemi sürecinin çocukları da etkilediği görülmüştür. Bu nedenle olumsuz kalıcı etkilerin oluşmaması için çocukların duygularını ifade edebilmesi için fırsat verilmesi, korku ve kaygılarının azaltılması üzerinde etkili olacaktır.
Comparative histomorphometry of postnatal skin development of heifers of 4 breeds of base and initial genotypes
Authors: Kyrylovskyy S. M.
Published: December 2022

The total thickness of the skin of the heifers of the four groups increased from 3 to 18 months of postnatal ontogenesis, depending on the breed, by 16–27 %. In the heifers of the base and original genotype breeds, different periods of completion of the growth of the skin thickness were established. In all four groups of heifers, there were fundamental differences in the dynamics of the growth of the thickness of the outer integument. The thickness of the epidermal layer of the skin reached maximum values in the early postnatal ontogeny of heifers. The thickness of the layers of the dermis of the heifers of the four groups increased with age, depending on the breed, by 33–43 % – papillary and 9–24 % – reticular. In the postnatal ontogenesis of the heifers of the four groups, the noticeable increase (more than 50 %) of the papillary layer of the dermis occurred in the early age period of 3–6 months, and the dynamics of changes in the thickness of the reticular layer depended on the breed of heifers. Structural transformations of its internal organization accompanied the postnatal development of the skin of the heifers of the four groups – the ratio of skin layers changed within 5–8 %, depending on the breed. In the dynamics of postnatal ontogenesis of heifers of the base and original genotype breeds, reliable differences in the thickness of the epidermis and the reticular (together with the subcutaneous base) skin layer was manifested, as well as the parameters of the growth ratio of the papillary/reticular layers of the dermis. The dependence of the parameters of the thickness of the epidermal barrier of the skin of heifers of the four groups on the period of the year and the seasonal differences in the growth of the papillary and reticular (together with the subcutaneous base) layers of the skin of heifers of the base and original genotype breeds indicate the probable corrective effect of environmental factors on the morphology of the skin of heifers and the difference in the manifestations of adaptation.

Kabul River Basin is the most populated and an important source of water resources in Afghanistan. The Soil and Water Assessment Tool (SWAT) model, together with the ArcGIS and SWAT-CUP, is employed to predict the runoff in the basin. Nine years of meteorological and hydrological data are employed in the study. The DEM, the soil cover, and the land use/cover data are downloaded from the available global database. The ArcGIS based soil classification, the land use/cover, the elevation, the drainage, and the slope distribution maps of the basin are generated. The meteorological data from 18 different stations and the hydrological data from 7 different stations are obtained from the Ministry of Energy and Water of Afghanistan. The basin is divided into 48 sub-basins with a total number of 770 hydrological response units (HRUs). The sensitivity analysis results revealed that the flow characteristics of KRB are highly influenced by the groundwater and snowmelt.  The model is calibrated using the data from 2010 to 2014 and validated employing the data from 2015 to 2017 at seven different hydrological stations. The SWAT-CUP is successfully used to calibrate the model for predicting monthly and daily runoffs. The calibrations and validations for the seven stations are achieved, on the average, with the correlation coefficient (R) of 0.78 (for daily flows) and 0.82 (for monthly flows), respectively. Total water yield in the basin is estimated to be 432.9 mm/year, corresponding to 31 176 Mm3/year, hardly meeting the demand of 26 512 Mm3/year in the basin.

Published: December 2022

This research has developed an alternative test method for determining hardened air void parameters that follows ASTM C457 Procedure C, but does not require image analysis software or the required training and skills to develop or use one. Instead, the alternative technique uses a sophisticated microscope that has on-board counting and measuring capabilities, that are easy to use and easy to repeat. The technique was developed and tested on concrete mixtures with four target air void percentages (control at 2%, low at 3 – 5%, medium at 5 – 7%, and high at >8%) and compared to ASTM C457 Procedure A and B. The concrete produced was a conventional pavement mixture, which was a straight cement mixture with a target 3” slump. The results show that the alternative technique is not only just as accurate as the other methods, but it reduces the analysis time, human judgment calls, and the development and maintenance of a sophisticated image analysis program, which are all typical issues with any of the three procedures described in ASTM C457. Additionally, the alternative technique produces all hardened air void parameters that ASTM C457 provides. This study also demonstrates new potential issues that could result in erroneous hardened air void results when following ASTM C457. Lastly, this study provides a detailed description of the equipment necessary to produce the alternative method including a very detailed list of steps required to obtained the hardened air void parameters.

Introduction: The advances in medicine, eradication and control of infectious diseases, as well as improvements in quality of life in recent decades, have brought greater longevity to the population, with the epidemiological transition of diseases taking place, with emphasis on Non-communicable Chronic Diseases, such as coronary heart disease. This research aims to identify the clinical parameters that the nursing team uses in the recognition of Cardiopulmonary Arrest in an Intensive Care Unit. Method: This is a descriptive research, with a qualitative approach, carried out in the intensive care center of a private hospital, located in the city of Belém, State of Pará. The participants were nursing professionals, who answered a semi-structured form, to analyze the actions and knowledge in emergencies in Cardiorespiratory Arrest by the clinically serious user. Results and Discussion: It can be observed that the participants identify a scenario of cardiorespiratory arrest through discomfort, facial expressions, pallor, difficulty breathing, vital signs, decreased cardiac output and saturation and absence of pulse. However, in relation to the behavior in the attendance, the research proved to be unsatisfactory in several approached aspects, it identified lack of knowledge of the nursing team in the taking of conducts and insecurity in the accomplishment of procedures. Conclusion: The performance of the nursing team in Cardiorespiratory Arrest must continue to be disseminated, aiming at greater safety and autonomy of these professionals, aiming at quality care, the nursing team must be able to attend to this type of clinical emergency, so that they can participate of constant training and updates, so that they become qualified and provide safe and effective care.
