Russian Labour Market Amidst Coronavirus Pandemic
Authors: Laykam K. E.
Published: October 2021

The article reﬂects the results of a statistical analysis of signifcant changes in the Russian labour market in 2020 amidst the spread of coronavirus infection. The study presents the results of a labour force survey organized for the frst time in Russia (following the ILO recommendations) through telephone interviews of respondents based on a representative sample.

The author analyzed the transformation of the Russian labour market in both the Russian Federation as a whole and regions using diﬀerent group forming criteria, in particular, types of economic activity, sectors of the economy, various socio-demographic characteristics of the population (gender, age, place of residence, etc.). The paper outlines the dynamics and structure of employment (including part-time work) and unemployment, as well as the results of a comparative analysis of the unemployment rate in Russia and a number of foreign countries. Other indicators of labour underutilization, including the potential labour force, are considered.

To conduct a comprehensive analysis of the eﬀects of the pandemic on the Russian labour market transformation indicators of dynamics of employees' wages are considered along with indicators of employment. At the same time, special attention is given to the analysis of the situation of personnel remuneration during the most severe period of the viral pandemic – in April 2020
Structural Shifts in the Economy of the Russian Federation and Its Import Intensity in 2014–2019: Analysis of Macroeconomic Statistics.
Authors: Strizhkova L. A. , Tishina L. I. , Selivanova M. V.
Published: October 2021

The introductory part of the article formulates its objective – to characterize development conditions in Russia and main structural changes in the Russian economy (according to 2014–2019 data) from the standpoint of their compliance with the tasks of increasing the stability and quality of the country's economic growth during the transition of the world system to a new technological order. Аccording to the authors, this period is of particular interest in assessing and studying the experience associated with structural transformation in a highly unfavorable external condition amid tight monetary policy and restrictive income policy.

The article sequentially addresses certain aspects of the structural transformation of the Russian economy. The authors, relying on macroeconomic statistics, assess shifts in production and use of products, investment, import intensity, the balance of payments, and international investment position, considering external and internal conditions.

The paper focuses on analyzing the proportions of the economy according to the data of the Rosstat input-output tables (IOTs). The article provides estimates of structural changes in the dependence of the economy and its segments on types of imports, signifcant changes in the direction of the use of fnal products, including considering the dynamics of changes in the total input of intermediate imports. For the frst time, the characteristics of the concentration of gross value added (GVA) and gross domestic product (GDP) by areas of fnal demand are given. A methodological approach is proposed for monitoring shifts in import consumption by compiling annual summary tables with a minimum set of data obtained during the analytical processing of IOT information. Based on the results of testing this approach on data for 2016 and 2018, the authors rated cost product balances by the share of imports in the resources of products. Conclusions were drawn about the change in the import intensity of the economy for the selected types of products, the import intensity of Russian industries, and shifts in the distribution structure of types of imported products. The article formulates proposals for the development of measures necessary to consolidate and expand positive results of this stage in the development of the Russian economy and statistical support of macroeconomic analysis.
The Application of Cointegration Method for Structural Data in the Estate Market Analysis
Authors: Bochenina M. V.
Published: October 2021

The article touches upon the topical issues of the residential real estate market, which are proposed to be solved by means of time series cointegration. The study aims to assess the structure of the housing market by types of apartments using price dynamics per one square meter of apartments' total area. The objectives of the study are to develop a methodology of determination of time series cointegration for the data with structural relationships; to analyze the average prices for the types of apartments on the primary and secondary housing market; to study the housing market in the Russian Federation by quarterly data of state statistics for the period 2000–2020 based on the developed methodology.

The results of the research showed that the prices at the primary and secondary housing market by types of apartments do not always represent an integrated process of the frst order and cannot be used for building a co-integration equation. This necessitated additional analysis and, as a consequence, the correction of the time period. It was proposed to ensure stationarity of linear combination of nonstationary data corresponding to the integrated process of the frst order by using the generalized least squares method (GLS). The sum of the elements of the cointegrating vector obtained this way tends to unity, and the elements themselves are estimates of the relative indi cators of the structure by types of apartments on the primary and secondary housing markets respectively. Thus, the suggested methodology allows estimating, on average, the share of the sold apartments of each type in the period under consideration, both in the regional context and in the country as a whole.

The proposed methodology can be used for the estimation of relative indicators of the structure according to temporal data in diﬀerent applications.
CONCEPTUALIZATION OF THE PHILOSOPHICAL TEXT IN THE STRUCTURES OF FOREGROUNDING
Authors: Shamshurin A.A.
Published: October 2021

The foregrounding of the text goes from a potential, not yet existing text to its relevance. In this march, the philosopher coincides with the philosophical text. This coincidence can be called a fore-text, which allows you to "enter" a philosophical text. The Internet considers hypertext as an informational formless set of texts, which is predetermined for the subject. The posed problem concerns the possibility of the presence of the subject in a digital hypertext. The aim of the study is to set the philosophical text as a concept, showing the subjectivation of the text with the help of the developed concept of a fore-text. To achieve the expected result, it is necessary to consider the history of philosophy as a chronological coherent sequence of texts, which is assumed as a context or common meaning. The problem is complicated by the fact that a single history of philosophy does not exist in digital space. It resides as a plurality of authors' histories of philosophy. The "introduction," "preface," etc. to a philosopher's text then becomes a "substitute" for the lost context. The development of the subjectivity of philosophy shows that the fore-text becomes the text itself. This development corresponds to the conceptualization of philosophy and its liberation from the authority of antiquity as traditionalism. Under the conditions of virtual reality and hypertext information, only conceptualization preserves the human in man - thinking. The author of the article poses the questions: "So what have we lost by asserting the end of the history of philosophy? Isn't the "new" pre-structure of the philosophical text the actualized "hyper-conceptual" space of the Internet?"

Influences of thickness, width, bend angle, applied load and holding time are evaluated over the springback in hot-rolled, high-tensile strength sheet-metals (JSH-440). Blanks' thickness, width and bend angles are considered the geometric parameters, whereas applied load and holding time are the process parameters considered in the research. Analysis of variance (ANOVA) and sensitivity analysis are applied to evaluate the significance of the factors over the springback magnitude. Analytical models are developed to predict the springback in the sheet metals for the desired geometric and process parameters. Simplified analytical models are also developed for different geometries of sheet metals. Finally, the Genetic Algorithm has also been applied to determine the optimal process parameters for the minimum springback with varying geometries of the sheet metals. Finally, the influence of parameters and optimized results are discussed in detail.

Published data on the hydrodynamics of ebullated- bed reactors (EBRs) used in the H-Oil process are scarce. In the present work, the effect of solid properties (e.g., particle size, and degree of hydrophobicity) on the hydrodynamics and foaminess in a lab-scale cold model of an (EBR) was investigated. 20wt. % MgSO4 solution was utilized as the liquid phase to imitate the hydrodynamic trends in the industrial-scale EBR of the hydro-conversion process. Experimental results depicted that the flow regime of the multiphase system can be readily evaluated by using the pressure drop technique. The turning from the bubbly to the turbulent system is enhanced with diminishing particle size, and decreasing particle hydrophobicity. Moreover, the degree of particle hydrophobicity was inversely proportional to the average gas holdup in the EBR. The reduction in average gas holdup was 7.9 % using hydrophobic particles more than that of the hydrophilic one. In the EBR, it was found that bubble sizes were increased with both gas velocity and the axial location far from the gas distributor while liquid velocity has negative impact on bubble size. The experimental work revealed that hydrophobic particles of smaller size (250 μrm) reduced foaming by 70% using 20 vol. % of solid loading and gas and liquid velocities of 10 and 0.15 cm s-1 respectively. This outcome revealed that the surface of catalyst particles used can be modified to act as foaminess- reducer in fluidized bed hydro conversion reactors.
On the Solution to Pre- Buckling of a Thin Rectangular Plate Subjected to a Thick Strip in-plane Loading
Authors: Nagler Jacob
Published: October 2021

The current paper deals with the problem of the simply supported thin rectangular plate subjected to the intermediate strip in-plane loading. Based on the strain energy method (Fourier ansatz), the critical (minimum value) of buckling stress occurrence was determined in a general form dependent only on the strip thickness, strip location, plate width and stress magnitude. Compatible with the classical columns Euler method it was found that the plate stability is decreased with the increasing of the plate width due to larger induced stresses. Also, strip location relative to the support region was found to influence the buckling (same analogy to the Euler buckling theory; consider the strip as a both sides pressed rod). Additionally, the strip width parameter increase is likely to cause larger buckling stress. Moreover, expressions that includes both axial and transverse loads for different extended cases configurations were also derived and examined based on the strain energy method alongside explanation for possible applications (thin aluminum plate welding). In a general view, it was found that the cases of combined axial and perpendicular loading action are less stabilized than cases where only one kind of loading configuration is participated. Finally, the buckling stress was found to agree qualitatively with the cited literature.

Violencia de género
Authors: Cuero Cesar
Published: October 2021

No hay duda que la violencia de todo tipo y género va aumentando en el mundo, y nuestra América Latina no escapa a esa realidad, antes bien es epicentro de la misma. A diario, los medios de comunicación social destacan estos hechos de violencia en primera plana o en la apertura de los noticieros, rindiendo culto al dios violencia, sin darse cuenta o bien en forma velada, de esa manera, trasmiten la sensación de que es muy importante la cobertura de estos hechos, como si no hubiera nada bueno que destacar en cada país y en la región latinoamericana en general.

En esta espiral de violencia, destaca la violencia de género, la agresión en la mayor parte de los casos de un hombre a una mujer, degenerando en daños físicos, materiales o en feminicidios. Y es que este es un fenómeno que no se queda en la esfera de la pareja, sino que afecta, cual bola de nieve, principalmente a los hijos, familiares y la sociedad en general, convirtiéndose en un problema en el que queda envuelto el estado y de el una buena cantidad de entidades ministeriales, secretarías, oficinas, que hacen mucho y hacen poco por resolver este complejo problema.

No hay duda, que los más afectados por esta irresponsable actitud, son los hijos del que ejecuta este delito, esta acción cobarde. Cuantos niños en nuestros países, quedan huérfanos de mamá y adicional sin papá, el cual al final se quita la vida, o permanece en prisión por un tiempo. No se detiene a pensar en sus hijos, como que ellos no tuvieran ninguna importancia.

La Organización Mundial de la Salud (OMS), ha considerado este problema como prioritario. La OMS define la violencia conyugal como cualquier comportamiento, dentro de una relación íntima, que cause o pueda causar daño físico, psíquico o sexual a los miembros de la relación. El hecho de que esta entidad haya considerado este problema para ser ventilado en su esfera dice a las claras la magnitud del mismo, que como ya señalamos va en aumento cada día.

Hace falta una acción enérgica de cada uno de los países, en especial los latinoamericanos, que con mano firme persiga y castigue a los que causan este delito social. Hace falta más educación en valores y buenas costumbres, que se ha perdido entre los jóvenes nuestros de esta época. Que los medios de comunicación tomen conciencia que estacando estos lamentables hechos de violencia contribuye a que se den más. Solo el esfuerzo mancomunado de la sociedad en todos sus niveles, la iglesia y el estado podrán frenar este mal que parece no tener fin.

Unámonos todos, como un solo haz de voluntades. Levantémonos con energía sostenida y decidida, y erradiquemos esa lacra social de una vez por todas.
Effects of Spin–Orbit Resonances and Tidal Heating on the Inner Edge of the Habitable Zone

Published: October 2021

Much attention has been given to the climate dynamics and habitable boundaries of synchronously rotating planets around low mass stars. However, other rotational states are possible, including spin–orbit resonant configurations, particularly when higher eccentricity orbits can be maintained in a system. Additionally, the oscillating strain as a planet moves from periastron to apoastron results in friction and tidal heating, which can be an important energy source. Here, we simulate the climate of ocean-covered planets near the inner edge of the habitable zone around M to solar stars with the NASA GISS ROCKE-3D general circulation model, and leverage the planetary evolution software package, VPLanet, to calculate tidal heating rates for Earth-sized planets orbiting 2600 and 3000 K stars. This study is the first to use a 3D general circulation model that implements tidal heating to investigate habitability for multiple resonant states. We find that for reference experiments without tidal heating, the resonant state has little impact on the radial position of the inner edge because for a given stellar flux, higher-order states tend to be warmer than synchronous rotators, but for a given temperature, have drier upper atmospheres. However, when strong tidal heating is present, the rotational component implies a strong dependence of habitable conditions on the system evolution and rotational state. Since tidal and stellar heating both decrease rapidly with orbital distance, this results in a compact orbital width separating temperate and uninhabitable climates. We summarize these results and also compare ROCKE-3D to previously published simulations of the inner edge.
The Occurrence-weighted Median Planets Discovered by Transit Surveys Orbiting Solar-type Stars and Their Implications for Planet Formation and Evolution
Authors: Schlaufman Kevin C. , Halpern Noah D.
Published: October 2021

Since planet occurrence and primordial atmospheric retention probability increase with period, the occurrence-weighted median planets discovered by transit surveys may bear little resemblance to the low-occurrence, short-period planets sculpted by atmospheric escape ordinarily used to calibrate mass–radius relations and planet formation models. An occurrence-weighted mass–radius relation for the low-mass planets discovered so far by transit surveys orbiting solar-type stars requires both occurrence-weighted median Earth-mass and Neptune-mass planets to have a few percent of their masses in hydrogen/helium (H/He) atmospheres. Unlike the Earth that finished forming long after the protosolar nebula was dissipated, these occurrence-weighted median Earth-mass planets must have formed early in their systems’ histories. The existence of significant H/He atmospheres around Earth-mass planets confirms an important prediction of the core-accretion model of planet formation. It also implies core masses M
c in the range 2 M
⊕ ≲ M
c ≲ 8 M
⊕ that can retain their primordial atmospheres. If atmospheric escape is driven by photoevaporation due to extreme-ultraviolet (EUV) flux, then our observation requires a reduction in the fraction of incident EUV flux converted into work usually assumed in photoevaporation models. If atmospheric escape is core driven, then the occurrence-weighted median Earth-mass planets must have large Bond albedos. In contrast to Uranus and Neptune that have at least 10% of their masses in H/He atmospheres, these occurrence-weighted median Neptune-mass planets are H/He poor. The implication is that they experienced collisions or formed in much shorter-lived and/or hotter parts of their parent protoplanetary disks than Uranus and Neptune’s formation location in the protosolar nebula.
Molecular Gas Filaments and Fallback in the Ram Pressure Stripped Coma Spiral NGC 4921

Published: October 2021

We investigate the effects of ram pressure on the molecular interstellar medium (ISM) in the disk of the Coma cluster galaxy NGC 4921 via high-resolution CO observations. We present 6″ resolution CARMA CO(1−0) observations of the full disk, and 0.″4 resolution Atacama Large Millimeter/submillimeter Array CO(2−1) observations of the leading quadrant, where ram pressure is strongest. We find evidence for compression of the dense ISM on the leading side, spatially correlated with intense star formation activity in this zone. We also detect molecular gas along kiloparsec-scale filaments of dust extending into the otherwise gas stripped zone of the galaxy, seen in Hubble Space Telescope images. We find the filaments are connected kinematically as well as spatially to the main gas ridge located downstream, consistent with cloud decoupling inhibited by magnetic binding, and inconsistent with a simulated filament formed via simple ablation. Furthermore, we find several clouds of molecular gas ∼1–3 kpc beyond the main ring of CO that have velocities that are blueshifted by up to 50 km s−1 with respect to the rotation curve of the galaxy. These are some of the only clouds we detect that do not have any visible dust extinction associated with them, suggesting that they are located behind the galaxy disk midplane and are falling back toward the galaxy. Simulations have long predicted that some gas removed from the galaxy disk will fall back during ram pressure stripping. This may be the first clear observational evidence of gas re-accretion in a ram pressure stripped galaxy.
Effect of Dust Rotational Disruption by Radiative Torques on Radiation Pressure Feedback from Massive Protostars
Authors: Hoang Thiem
Published: October 2021

Radiation pressure on dust is thought to play a crucial role in the formation process of massive stars by acting against gravitational collapse onto the central protostar. However, dust properties in dense regions irradiated by the intense radiation of massive protostars are poorly constrained. Previous studies usually assume the standard interstellar dust model to constrain the maximum mass of massive stars formed by accretion, which appears to contradict dust evolution theory. In this paper, using the fact that stellar radiation exerts on dust simultaneous radiation pressure and radiative torques, we study the effects of grain rotational disruption by radiative torques (RATs) on radiation pressure and explore its implications for massive star formation. For this paper, we focus on the protostellar envelope and adopt a spherical geometry. We find that originally large grains of micron sizes presumably formed in very dense regions can be rapidly disrupted into small grains by RATs due to infrared radiation from the hot dust shell near the sublimation front induced by direct stellar radiation. Owing to the modification of the size distribution by rotational disruption, the radiation pressure opacity can be decreased by a factor of ∼3 from the value expected from the original dust model. However, to form massive stars via spherical accretion, the dust-to-gas mass ratio needs to be reduced by a factor of ∼5 as previously found.
Uniqueness and numerical reconstruction for inverse problems dealing with interval size search
Authors: Apraiz Jone , Cheng Jin , Doubova Anna , Fernández-Cara Enrique , Yamamoto Masahiro
Published: October 2021

We consider a heat equation and a wave equation in one spatial dimension. This article deals with the inverse problem of determining the size of the spatial interval from some extra boundary information on the solution. Under several different circumstances, we prove uniqueness, non-uniqueness and some size estimates. Moreover, we numerically solve the inverse problems and compute accurate approximations of the size. This is illustrated with several satisfactory numerical experiments.
Hospital Management Maturity Models: Literature Review
Authors: Trentin Luciano , Tontini Gérson
Published: October 2021

Previous researches show that hospital organizations have initiated improvement programs and invested considerably in the orientation and management of processes, using maturity models to improve structures and learning. In this context, the objective of the present paper is to analyze previous researches related to hospital management maturity models, using the Morton (1994) organizational dimensions' analysis model, adapted for hospital organizations. The Web of Science, Scopus, Spell, Scielo and BDTD platforms were used for this study. We screened 305 identified papers, published from January 2005 till December 2019, using search descriptors: “Maturity Model” and “Hospital management". We identified Forty-one articles as eligible for information extraction and analysis. The surveys are classified into five organizational dimensions: Strategy, Structure, Decision Making, Technology, and People. We found a predominance of the technology management dimension in 25 studies, based on the organizational dimensions. The research is essentially related to information systems, supply management and quality management. Although there are different models of hospital management maturity, it was found that the models developed for hospital organizations are mostly related to their technical / operational areas, but in a fragmented way. The present study contributes to a comprehensive literature review of hospital maturity and management models.
Separação equivocada entre política e saúde:
Authors: Ferreira Fernanda Vasques , Varão Rafiza
Published: October 2021

Qualquer problema dos cenários públicos faz parte daqueles sobre os quais as políticas públicas devem se debruçar, incluindo a saúde dos cidadãos. Após o anúncio da pandemia da Covid-19 no Brasil, emergiu uma discussão equivocada acerca da separação entre as questões de saúde e aquelas concernentes à política. Este texto tem como objetivo analisar de que maneira essas questões aparecem em quatro materiais jornalísticos publicados no Correio Braziliense, na Jovem Pan, nos portais de notícias UOL e IG e confrontá-los com com texto de ampla circulação nas mídias sociais, atribuído erroneamente ao filósofo e educador Mario Sérgio Cortella. Consideramos o contexto de desinformação e de proliferação de fake news em detrimento da formulação e discussão de políticas públicas efetivas para redução dos impactos da doença na saúde e na vida dos cidadãos. Para realizar a análise, foi utilizado o método da análise de conteúdo, conforme bases preconizadas por Bardin (2011), com inferências advindas da reflexão teórica sobre saúde e comunicação (GAVILANES, 2009;  TABAKMAN, 2013; ARAÚJO, 2014;  entre outros). Conclui-se que os equívocos acerca da saúde como objeto da política não se restringem apenas ao texto amador, mas também àqueles produzidos pelo jornalismo profissional aqui analisado.
Infodemia e Instagram: como a plataforma é apropriada para a produção de desinformação sobre a hidroxicloroquina?
Authors: Soares Felipe Bonow , Bonoto Carolina , Viegas Paula , Salgueiro Igor , Recuero Raquel
Published: October 2021

Neste artigo, analisamos as estratégias de apropriação do Instagram para a produção de discursos desinformativos sobre o Covid-19. O nosso estudo de caso é focado na divulgação do uso da hidroxicloroquina como tratamento para a doença. Para isso, coletamos publicações na plataforma que mencionavam o medicamento. Selecionamos as 67 publicações desinformativas com maior número de interações e utilizamos Análise de Conteúdo para identificar como a multimodalidade foi apropriada na produção discursiva e quais foram as estratégias de legitimação utilizadas nas publicações. Nossos resultados mostram diferentes apropriações para vídeos e imagens, com vídeos utilizados como evidências e imagens dependendo de níveis textuais na legenda ou em sobreposições. Entre as estratégias de legitimação, houve prevalência da categoria de autorização, em publicações que mencionavam a produção e distribuição da droga e a sua inclusão em protocolos de tratamento da doença. A avaliação moral foi a segunda categoria mais utilizada, apropriada para a crítica a atores políticos. Mitopoesia, que tratava de casos de pessoas recuperadas que utilizaram hidroxicloroquina, e racionalização, que dava destaque a estudos que supostamente comprovavam a eficácia do medicamento, foram categorias menos comuns. 
 
PALAVRAS-CHAVE: Covid-19; desinformação; Instagram; multimodalidade, plataforma.
A Proposal to Distinguish DDoS Traffic in Flash Crowd Environments
Authors: Alves da Silva Anderson Aparecido , Silva Leonardo Santos , Bezerra Erica Leandro , Guelfi Adilson Eduardo , de Armas Claudia , Teixeira de Azevedo Marcelo , Kofuji Sergio Takeo
Published: October 2021

A Flash Crowd (FC) event occurs when network traffic increases suddenly due to a specific reason (e.g. e-commerce sale). Despite its legitimacy, this kind of situation usually decreases the network resource performance. Furthermore, attackers may simulate FC situations to introduce undetected attacks, such as Distributed Denial of Service (DDoS), since it is very difficult to distinguish between legitimate and malicious data flows. To differentiate malicious and legitimate traffic we propose applying zero inflated count data models in conjunction with the Correlation Coefficient Flow (CCF) method – a well-known method used in FC situations. Our results were satisfactory and improve the accuracy of CCF method. Furthermore, since the environment toggles between normal and FC situations, our method has the advantage of working in both situations.

Published: October 2021

Mobile or IOT based applications are emerging rapidly across the globe and there is a massive digital transformation happening within each country. It is a need of an hour to improve and protect digital identity during online transactions through handheld devices. This paper proposes a Mobile ID solution based on Mobile-originated PKI without the need for the actual identity card or a card reader. The solution proposed focuses on security, privacy, and usability using open standards which will protect Personally Identifiable Information (PII) over handheld devices. The proposed mobile ID solution has better cost-efficacy and privacy than today’s scenario. It also explicates the Mobile ID solution with established secure identity among users, authorities, other organizations of public, and private sectors.

Background and objective: Today, COVID-19 outbreak has become a global alert. So, lots of medical complications and socioeconomic and mental burdens have arisen following the outbreak of the disease. There is no adequate general strategy for total control of the virus’s widespread. According to this, preventive or early diagnostic measures are crucial. In this study, we designed a questionnaire in the context of the 4030 telephonic platform to assess the most common symptoms of COVID-19 in Iran.

Materials and Methods: A questionnaire that had been designed with 20 common and rare symptoms of COVID-19 was filled out by 115 operators of 4030, a 24-hour call center to answer the Iranians' questions associated with COVID-19 and screen probable COVID-19 cases.

Results: Common COVID-19 symptoms among people included cough, dyspnea, sore throat, myalgia, headache, anosmia, fever, dysgeusia, chilling, lethargy, and fatigue. Also, less common symptoms were rhinorrhea, sneeze, vomiting, diarrhea, nasal congestion, eyesore, stomach ache, jaw pain, dry mouth, and abdominal cramps.

Discussion and Conclusion: Our study showed that the most common symptoms of COVID-19 in Iran include cough, dyspnea, sore throat, myalgia, headache, anosmia, fever, dysgeusia, chilling, lethargy, and fatigue. Some symptoms may incident due to over-use of disinfectants, or aggravated by fear of infection, or misdiagnosed with other issues such as food poisoning, flu, panic attacks, and allergies. Consequently, It seems that screening can help find new cases who haven’t refered to hospitals and health care centres, and this can result in COVID-19 improving, Covid-19 management, and decreasing the costs of patients and health systems.
Vivir en el encierro: interacciones en un Centro de Tratamiento para Adolescentes
Authors: Fernández Huerta Christian , Figueroa Estrada Anuar
Published: October 2021

Este artículo abordó el significado que los jóvenes les otorgan a las interacciones sociales dentro del Centro de Tratamiento para Adolescentes (CTA) y al proceso de reinserción social proporcionado por el Estado y que han ingresado a dicho centro. Debido a la falta de permiso para grabar audio y/o video dentro de las instalaciones del CTA, se optó por talleres donde se abordaron distintos temas relacionados con la violencia, la familia, expectativas sobre su futuro, entre otros; con la finalidad de registrar a través de dibujos, cuestionarios y relatos, sus vidas antes del delito y sus estancias dentro del CTA. En el camino a la reinserción social, estos jóvenes cargan un estigma que no disminuye y conforme se acerca el fin del tratamiento crece la incertidumbre de volver al exterior, pues la habituación a las normas institucionales del encierro implica también un trabajo de readaptación a la vida en libertad.
Zastupljenost žena u upravljačkim strukturama odabranog hrvatskog farmaceutskog poduzeća
Authors: Perkov Matej
Published: October 2021

U ovome radu govori se o stanju ravnopravnosti spolova u Republici Hrvatskoj te aktivnostima i mjerama koje se u tom području poduzimaju za
smanjenje ili uklanjanje neravnomjerne zastupljenosti muškaraca i žena u
upravljačkim strukturama. Cilj je rada prikazati izazove nerazmjerne zastupljenosti muškaraca i žena na rukovodećim pozicijama u europskim i hrvatskim poslovnim organizacijama. Ravnopravnost spolova predstavlja stratešku srž razvoja svih politika EU jer ni jedna država članica nije još postigla potpunu ravnopravnost. Zadnjih nekoliko dekada Europska je unija učinila značajan iskorak u smanjenju disproporcija kako bi se u praksi provelo načelo jednakosti spolova. Europska komisija želi da najmanje polovica žena bude u upravljačkim strukturama, ali će EU – ako se nastavi današnja dinamika – ostvariti ravnopravnost spolova tek za 60
godina! Svojim znanjima, vještinama i sposobnostima žene su postale ravnopravne kandidatkinje za članice upravljačkih struktura. Na međunarodnoj, regionalnoj i nacionalnoj razini poduzimaju se brojne mjere, donose strategije, planovi djelovanja, međunarodni ugovori, zakoni i drugi propisi,

a s ciljem postizanja stvarne ravnopravnosti žena i muškaraca u svim područjima privatnog i javnog života. Istraživačka je hipoteza da u upravljačkim strukturama ravnopravnost spolova nije adekvatna.

Zaposlenici u turističkom sektoru snažno su izloženi riziku obolijevanja
od zaraznih bolesti, posebno oni koji su u direktnom kontaktu s gostima
iz cijelog svijeta poput hotelskog osoblja, turističkih vodiča, zrakoplovnog osoblja i slično. Rizik je tim veći što do prijenosa zarazne bolesti može doći kada još simptomi zaraze kod osoba nisu manifestirani. Također, zaposlenici u turističkom sektoru mogu biti izravni prenositelji zaraznih bolesti u određenom trenutku, a da toga nisu ni svjesni. Turistička i druga putovanja u takvom slučaju mogu poslužiti kao izvrstan medij za prenošenje zaraznih bolesti u vrlo kratkom vremenu iz jednog područja u drugo, s jednog kontinenta na drugi. Zaposlenici turističkog sektora trebaju znati zaraznu bolest prepoznati u ranoj fazi te promptno pristupiti poduzimanju zaštitnih mjera. Predmet ovog rada podrazumijeva vrlo aktualnu problematiku koja se odnosi na zaštitu zdravlja zaposlenika u turističkom sektoru s naglaskom na zaštitu od zaraznih bolesti. Cilj je rada analizirati suvremene mehanizme zaštite zdravlja turističkih djelatnika od obolijevanja od zaraznih bolesti u svijetu, a time i u Republici Hrvatskoj
Оцінка змін гемодинаміки у постраждалих військовослужбовців із мінно-вибуховими пораненнями в процесі аеромедичної евакуацій
Authors: Khytryi G. P. , Ukhach Yu. D.

Вступ. Швидка медична евакуація шляхом аероевакуації до місць надання кваліфікованої та спеціалізованої допомоги стала більш ефективною з часів Другої світової війни та визнана ефективною у спроможності "очищення поля бою" та прискорення евакуації постраждалих до лікарень та клінічних центрів. Тим не менше, вплив аеромедичної евакуації на пацієнтів з політравмою все ще недостатньо зрозумілий, особливо у випадку масової евакуації, коли широкому колу пацієнтів може знадобитися сортування в суворих або екстремальних умовах із обмеженою доступністю.

Мета роботи. Оцінити гемодинамічні зміни під час проведення аеромедичної евакуації у постраждалих із політравмою та із проникаючими пораненнями голови.

Матеріали та методи. Проведено ретроспективний аналіз карт інтенсивної терапії 32 поранених та травмованих військовослужбовців, яким проводилася аеромедична евакуація із зони проведення АТО/ООС протягом 2017-2018 рр.

Результати. На першому етапі дослідження було встановлено, що рівень САТ на наземному етапі евакуацій у групі із мінно-вибуховими проникаючими пораненнями голови становив 91,4±5,9 мм рт. ст., в той час як у постраждалих із мінно-вибуховими пораненнями живота та/або грудної клітки він був значно нижчим та становив 87,5±4,8 мм рт. ст.(р<0,05). Показники пульсу становили 75,1±4,7 та 79,4±5,1 уд/хв. у досліджуваних групах відповідно (р<0,05). На другому етапі дослідження встановлено статистично достовірне зниження показників гемодинаміки та наростання ЧСС у постраждалих обох груп у порівнянні із вихідними даними. Так у 1-й групі САТ становив 85,4±4,8 мм рт. ст., ЧСС 82,1±6,3 (р<0,05), а у другій – 82,7±4,9 мм рт. ст., ЧСС 86,2±5,8 (р<0,05). На подальших етапах (20 та 40 хвилина) аеромедичної евакуації відмічалась поступова стабілізація гемодинаміки. На завершальному етапі евакуації в обох досліджуваних групах показники ЧСС та САТ знаходилися в межах значень, отриманих на наземному етапі.

Висновки. В результаті проведеного дослідження встановлено, що на другому етапі дослідження (підйом на висоту) спостерігалися достовірні зміни гемодинамічних показників, які проявлялися гіпотензією та тахікардією (р<0,05), які поступово були медикаментозно кореговані, та починаючи з 3 етапу (20 хв.) повернулися до вихідних значень в обох досліджуваних групах. У постраждалих із мінно-вибуховими пораненнями живота та/або грудної клітки на 4-му етапі дослідження спостерігалося зниження САТ, що може вказувати на більшу гемодинамічну нестійкість у даній досліджуваній групі.
