Jerarquización castrense en el Colegio Militar Leoncio Prado de La ciudad y los perros (1963)
Authors: Delgado Del Aguila Jesús Miguel
Published: October 2020

Esta obra literaria de Mario Vargas Llosa plasma una configuración asimétrica en sus personajes. Esta es distintiva de la condición moderna que justifica su inestabilidad ontológica, tal como lo constata Milagros Ezquerro. A su vez, se comprende por el contexto en el que se desarrolla: etapa dictatorial que se atraviesa en el Perú y Latinoamericana en la segunda mitad del siglo XX. Retomando esta premisa, este artículo tendrá como objetivo fundamentar cuáles son los enclaves que delimitan y convergen la constitución de las jerarquías que adoptan las autoridades responsables y los cadetes que oscilan en el universo castrense de la novela. Para ello, se corroborará con la noción de violencia que fluctúa Walter Benjamín, la concepción de espacio de Iuri Lotman y el paradigma del universo militar que aborda Herbert Morote. Estas categorías se imbricarán para demostrar con triángulos jerárquicos la implicancia que se alcanzó con este tipo de instrucción.

Le Petit Prince y la imaginación de lo invisible
Authors: Abellán-García Barrio Álvaro
Published: October 2020

Le Petit Prince ha suscitado reflexiones en diversas disciplinas y su valor teórico ha sido reconocido por importantes filósofos contemporáneos. Este artículo muestra que Saint-Exupéry pretende en esta obra ensayar una «forma de mirar», una gnoseología capaz de recuperar la visión de las realidades invisibles que dan sentido a la vida humana. Justificaremos esta lectura desde la tradición poética aristotélica actualizada en la teoría y metodología hermenéutica de autores como Paul Ricoeur y Alfonso López Quintás.

Reflexões sobre o uso do big data em modelos preditivos de vigilância epidemiológica no Brasil
Authors: Massato Harayama Rui
Published: October 2020

Objective: to discuss the bioethical implications from the announcement of Digital Health by the World Health Organization and the use of big data in the production of predictive health surveillance systems in Brazil. Methods: conducted a narrative review based on the search for articles on Scielo, Bireme, Jstor platforms and at the World Health Organization and the Ministry of Health of Brazil webpages, with the keywords big data, bioethics and ethics, from May to July 2020. Results: limits were evidenced in the use of big data as an epidemiological forecasting surveillance tool, notably with its use during the Covid-19 pandemic, although justified by the Bioethics of Protection Theory and Public Health Ethics. The greatest limits observed were the absence of adequate data protection legislation and bias in the data obtained. Conclusion: in order to analyze the bioethical impacts of the use of big data in the medicine of the future, it is essential to deepen the discussion on the possible impacts that the use of these technologies can have on life in society, with an emphasis on the development of surveillance capitalism, on interference in life and the intensification of regional inequalities.
Teleconsulta médica: os limites éticos e o risco de negligência informacional
Authors: Calado Vinicius de Negreiros , Lamy Marcelo
Published: October 2020

Objective: to analyze the current legislation on teleconsultation, based on the concept of medical consultation and the need for the physical examination of the patient for its characterization, as well as the limitations imposed by the Code of Medical Ethics (CEM) of the Federal Council of Medicine (CFM), and by the opinions and resolutions of the Regional Councils, aiming to point out its limits and risks of informational medical negligence. Methods: qualitative and integrative review of current legislation, specialized medical and legal literature on the issue. Results: The practice of telemedicine is regulated by the Federal Council of Medicine (CFM), but teleconsultation is not expressly recognized by the entity. After the entry into force of the Administrative Rule No. 467/2020 from Ministry of Health (MS) and Law No. 13.989 / 2020, which expressly allows for teleconsultation in an exceptional and transitory nature, it was found that the Regional Councils of Medicine of the states adopted divergent positions regarding the theme. It was also evident that the opinion of the Federal Council of Medicine No. 14/2017 is binding and allows a "communication" between the doctor and his patient by technological resources, as long as these are already served by him. Conclusion: teleconsultation is an ethical and possible medical practice, since it is not prohibited by CFM Resolution No. 1,643 / 2002, addressed directly in Opinion CFM nº 14/2017, but it depends on a previous doctor - patient relationship for ordinary situations, being deferred (and never dispensed) in emergency situations, being the formalization of digital informed consent by any means of information and communication technology is necessary, as long as it guarantees the integrity, security and confidentiality of information.

Authors: Vidal de la Fuente Sofía , Real Ramírez Janet , Ruíz Rosas Jesús Abrahán , Morera González Daniela
Published: October 2020

Introduction. Since mental health disorders are an emerging problem in medical residents, its detection and attention must be a priority. Objetive. To compare the frequency of psychopathology in residents according to sociodemographic and clinical characteristics. Method. We conducted a cross-sectional study evaluating the presence of psychopathology, as well as sociodemographic and clinical characteristics in 644 residents through online questionnaires. Results. Among participants, 55.7% reported a psychiatric disorder at some point and 29.2% a current one; only 41.5% were under treatment. Additionally, 8.1% had attempted suicide, of which 32.4% attempted it during residency. We found that 6.5% of women and 3.3% of men presented “risk of psychopathology,” with a higher percentage of men presenting “severe psychopathology.” Individuals with “risk of psychopathology” presented significantly higher scores on all of the questionnaires, compared to those with “absence of psychopathology.” Discussion and conclusion. Residents with occupational stress also presented higher risks of psychopathology, suicide, and substance use. Being under psychiatric treatment significantly improved the scores on the different scales. Because residency is a period that may increase the probability of suffering psychopathology, interventions should be aimed at reducing occupational stress and bringing specialized care.

Published: October 2020

Introduction. Burnout syndrome (BOS) comprises emotional exhaustion, depersonalization, and reduced personal accomplishment in those affected. Instruments such as the Maslach Burnout Inventory (MBI) can help to identify those affected. Physicians in training have been described as an at-risk group for this syndrome. Objective. Describe the association between BOS and medical training by specialty in first-year residents. Method. This is a cross-sectional analytical study of specialty residents at the Hospital Civil de Guadalajara. Sociodemographic data were obtained and the MBI was administered to identify BOS. Samples were compared, and a comparative analysis performed to identify factors associated with BOS. Results. Eighty-eight residents were included, with 21.6% (n = 19) presenting BOS, 53.4% displaying emotional exhaustion (n = 47), 53.7% showing depersonalization (n = 47), and 39.8% reduced personal accomplishment (n = 35). Presenting BOS was not associated with sociodemographic characteristics or type of specialty. Work hours (ro = .229, p = .032), and a higher number of on-call hours/week (ro = .34, p = .001) were associated with higher BOS. Discussion and conclusion. The prevalence of BOS was lower than expected. Over half scored for emotional exhaustion and depersonalization, which could be explained by a self-reporting bias. There was no association between the group/type of specialty and BOS. This study creates new knowledge that works as an institutional situational diagnosis, helps to determine the scope of the problem, and encourages to consider the contributing factors to its origin and maintenance.
2005-2015 Perspektifinden Amerika Birleşik Devletleri’nin Sahraaltı Afrika Politikası ve Afrika Komutanlığı (AFRICOM)
Authors: Özel Yücel , Şahin Güngör
Published: October 2020

Uzun yıllar uluslararası sistemde incelenmeye değer görülmeyen ve Soğuk Savaş’ın kutupları ABD ve SSCB açısından hak ettiği ilgiyi göremeyen Afrika, iki kutuplu sistemin çöküşüyle birlikte başta Sahraaltı Afrika olmak üzere yeniden ilgi odağı haline gelmeye başlamıştır. 2008 yılında küresel düzeyde yaşanan finansal kriz, dünya genelinde güçler arasındaki rekabeti şiddetlendirmiş, Afrika’nın sahip olduğu kaynaklar açısından çekiciliğini gündeme getirmiştir. Kriz sonrasında Afrika, ABD ile birlikte yükselen güçlerin (Brezilya, Rusya, Hindistan, Çin, Türkiye) rekabetinde dönüm noktasına ulaşmıştır. 2005 yılı sonrasında ABD kıtaya gerçek anlamda ilgi göstermeye başlamış, 2007 yılında Afrika Komutanlığı’nın (AFRICOM) kuruluşuyla birlikte ABD’nin Afrika politikası, Savunma Bakanlığı ve Dışişleri Bakanlığı’nın görev ve teşkilatı üzerinde uzlaşı sağladığı AFRICOM ile daha uygun bir zeminde uygulama alanı bulmuştur. ABD’nin, günümüz uluslararası ilişkiler teori ve analizlerinin henüz tam olarak uygulanabilir olmadığı Sahraaltı Afrika’ya yönelik 2005-2015 yılları arasında uyguladığı politika, Afrika’nın değişiminde ve yerel güç dengelerinde etkili olmuş, aynı zamanda terörle mücadelede bir dönüşüm gerektirmiştir. ABD dış politika kararlarının alınmasında iç ve dış kamuoyunun etkisi olmakla birlikte, Afrika ülkelerinde kimliğe ve geçmişe dayalı dış tehdit algısı da bu politikaların belirlenmesinde önemli olmuş, 2008 yılı sonrasında ABD’nin Afrika’daki faaliyetleri ulusal çıkarlarını gerçekleştirecek tarzda özenle seçilmiş ve yönlendirilmiştir.
Curricular Contradictions: Negotiating Between Pursuing National Board Certification and an Urban District’s Direct Instruction Mandate
Authors: BRISTOL TRAVIS J. , ESBOLDT JOY
Published: October 2020

In this article, Travis J. Bristol and Joy Esboldt examine the supports and constraints teachers at one midsized urban school serving predominately Latinx students encountered during school-based professional development aligned with becoming a National Board Certified Teacher (NBCT). Research has established that Black and Latinx students have less access to NBCTs when compared to White students, yet few studies offer insight into the organizational conditions that influence urban school teachers’ capacity to earn certification. Drawing on two years of ethnographic observations, interviews, and artifact analysis, this study finds that district and school-based factors constrained teachers’ capacity to earn National Board Certification, reporting that participants believed there was a misalignment between the district’s vision for instructional improvement, which focused on Direct Instruction, and the National Board for Professional Teaching Standards.
The experience of using “ChitoPran” wound coating for treating a patient with combined injury
Authors: Bogdanov Sergey B. , Karakulev Anton V. , Gilevich Irina V. , Melkonyan Karina I. , Polyakov Andrey V. , Sotnichenko Alexander S.
Published: October 2020

Background. Resolution of problems related to burn injuries remains relevant and extremely complex in the modern medicine. Biological wound coatings are actively used in the treatment of patients with burn injury. Researchers at the Scientific Research Institute at the Ochapovsky Regional Clinical Hospital No. 1 have been using the biological wound coating ChitoPran since 2017. This coating creates a dry environment in the wound for borderline depth burns and after autoplasty, which contributes to the acceleration of epithelization. For deeper burns after necrectomy, the ChitoPran accelerates the growth of granulation tissues.
Clinical case. This article presents the clinical case of the successful treatment of a 17-year-old burn patient with a combined injury. The patient presented with a blunt abdominal injury on the background of a deep burn of the anterior abdominal wall. The patient underwent a median laparotomy on the first day and an early necrectomy with primary cutaneous autoplasty with the ChitoPran closing of the wounds on a day later.
Discussion. The use of the ChitoPran wound coating in combination with skin autoplasty for the early surgical treatment of burns contributes to the acceleration of epithelization of wounds in comparison with stage-based surgical treatment. This coating is hence comparable in terms of cellular epithelization with the use of fibroblasts.
Conclusions. Creating optimal conditions for epithelization in the wound can prevent the development of purulent complications (such as the failure of skin sutures of the anterior abdominal wall). The use of ChitoPran wound coating showed improved outcomes in the treatment of patients with burn injuries through accelerated restoration of the skin and reduced suppuration in the wound.

Authors: Melkumova L.E. , Shatskikh S. Ya.
Published: October 2020

The present work deals with quantile Pfaﬃan diﬀerential equations which are constructed using two-dimensional conditional quantiles of multidimensional probability distributions. As it was shown in [3] in case when the initial probability distributions have reproducible conditional quantiles this kind of Pfaan equations is completely integrable and the integral manifold is the conditional quantile of maximum dimension. In this paper we discuss properties of integral manifolds of maximum possible dimension for quantile Pfaﬃan equations which are not completely integrable. Manifolds of this type are described in terms of conditional quantiles of intermediate dimensions.

This paper is devoted to the varieties of Leibnitz algebras over a ﬁeld of zero characteristic. All information about the variety in case of zero characteristic of the base ﬁeld is contained in the space of multilinear elements of its relatively free algebra. Multilinear component of variety is considered as a module of symmetric group and splits into a direct sum of irreducible submodules, the sum of multiplicities of which is called colength of variety. This paper investigates the identities that are performed in varieties with ﬁnite colength and also the relationship of this varieties with known varieties of Lie and Leibnitz algebras with this property. We prove necessary and suﬃcient condition for a ﬁniteness of colength of variety of Leibnitz algebras.

Authors: Trushina D.A. , Vedyasova O.A. , Paramonova M.A.
Published: October 2020

Registration of electroencephalogram (EEG) in the right-handed students during an exam revealed weakening of alpha rhythm in all areas of right and left cerebral hemispheres as well as increased beta rhythm in parietal and end-lobes of the right hemisphere. Simultaneously regular delta waves in the frontal leads ofboth hemispheres and theta waves in right frontal, occipitalis and temporal leads were marked. Oﬀset of EEG slow wave activity in the right hemisphere in partial right-handers was marked in more noticeable way than in that of the true right-handers. The obtained data suggest that the distribution of EEG rhythms in condition of mental and emotional stress in right-handers depends on the type and severity of functional hemispheric asymmetry.

On the optimal control of the n-fold integrator
Authors: Gorelov Yu.N.
Published: October 2020

The optimal control problem n-fold integrator with arbitrary boundary conditions and functionals of type norms in spaces of Lq[t0; tf ], q = 1; 2;1 is considered. First, it is the problem of minimizing the total controling impulse, which boils down to L1- problem of moments; secondly, the problem of minimizing the maximum values of the control parameter (represented as L1-problem of moments), and, finally, it is the problem of minimizing ”generalized work control” (as L2-problem of moments). Solving problems is obtained by using the method of moments in the form of the maximum principle by N.N. Krasovsky. It is shown that optimal control in the first problem is approximated by a -impulsive control. Conditions for the existence of regular and singular solutions to this problem depending on the boundary conditions are also specified. The general solution of the second problem, which is the conditions for existence of regular and singular solutions and not equivalence with the mutual problem of time-optimal control is obtained. Examples of solution for the considered control tasks are given. In case of a quadratic functional general relations required for constructing a program optimal control were obtained.

Published: October 2020

The study of condition of the system of hemoglobin, release of peptide com- pounds, and proteolytic activity of human erythrocytes under conditions of hy- perglycemia of varying degrees is carried out. The increase in the level of hy- perglycemia is accompanied by a decrease of aﬃnity of hemoglobin to oxygen and the growth of level of metgemoglobin, the glycosylated hemoglobin level is increased in conditions of severe hyperglycemia. The level of formation of pep- tides in erythrocytes and the level of output of their cells is determined by the increase in trypsin-like activity in cytosol and increased membrane permeability of red blood cells.

On the solvability of spatial nonlocal boundary value problemsfor one-dimensional pseudoparabolic and pseudohyperbolic equations
Authors: Popov N.S.
Published: October 2020

In the present work we study the solvability of spatial nonlocal boundary value problems for linear one-dimensional pseudoparabolic and pseudohyperbolic equations with constant coeﬃcients, but with general nonlocal boundary conditions by A.A. Samarsky and integral conditions with variables coeﬃcients. The proof of the theorems of existence and uniqueness of regular solutions is carried out by the method of Fourier. The study of solvability in the classes of regular solutions leads to the study of a system of integral equations of Volterra of the second kind. In particular cases nongeneracy conditions of the obtained systems of integral equations in explicit form are given.

Published: October 2020

In this paper a problem for which the origin problem was a problem known as the Lagrange problem or the problem on ﬁnding the form of the ﬁrmest column of the given volume is viewed. The Lagrange problem was the source for diﬀerent extremal eigenvalue problems, among them for eigenvalue problems for the second-order diﬀerential equations, with an integral condition on the potential. In this paper the problem of that kind is considered under the con- dition that the integral condition contains a weight function. The method of ﬁnding the sharp upper estimates for the ﬁrst eigenvalue of a Sturm - Liouville problem with Dirichlet conditions for some values of parameters in the integral condition was found and attainability of those estimates was proved.
