Historia Natural de la Enfermedad: Sarampión
Authors: Sánchez-Martínez Diana V. , García-Rivera Zaira L.
Published: July 2022

La Historia Natural de la Enfermedad es el proceso de evolución de la misma, desde la interaccion del agente causal con el huésped y el medio ambiente (triada ecológica) hasta su resolución, sin intervención medica. En 1965 Leavell y Clark diseñaron un modelo para representar de manera gráfica este desarrollo y lo relacionaron con los niveles de prevención. En esta representación se identifican dos períodos, el periodo prepatogénico que esta relacionado con la triada ecológica y el periodo patógenico que incluye la fase subclinica y clínica, en las que se presentan alteraciones fisiológicas  en el organismo para concluir con la resolución de la enfermedad a través de la recuperación, cronicidad o muerte.

Published: July 2022

La segunda ley de la termodinámica se basa respecto al calor que fluye de un objeto frío a un objeto caliente, la cual establece la irreversibilidad de los fenómenos físicos, se sabe que no es posible la creación de una máquina que sea capaz de convertir de manera continua la eficiencia y la energía térmica. En otros términos, también establece que, si todo el trabajo mecánico puede transformarse en calor, no todo el calor puede transformarse en trabajo mecánico.

  El objetivo de reconocer la relevancia de la segunda ley de la termodinámica en nuestro propio contexto, es principalmente adaptar su utilidad en diversos puntos de vista, además de que con los resultados que podamos obtener, nosotros determinemos los estados de equilibrio a los que eventualmente arribe un sistema compuesto cerrado cuando se eliminan   ciertos vínculos internos que pueda poseer un sistema.

Published: July 2022

El conocimiento sobre los procesos que se suscitan durante la respuesta sexual humana se circunscribía a descripciones inexactas, las primeras aproximaciones al estudio de la respuesta sexual se le atribuyen a Havelock Ellis, Wilhelm Reich y Alfred Kinsey. Durante la década de los años 60, surgió un gran interés por conocer y contextualizar la comprensión de los eventos fisiológicos que se presentan durante la respuesta sexual. Los descubrimientos y avances sobre el tema, fueron atribuidos a las investigaciones realizadas por William H. Masters y Virginia Johnson, quienes en 1966 publicaron el libro: La respuesta sexual humana, describiendo con detalle la secuencia del proceso, sobresale en esta obra la sistematización de modificaciones a nivel genital y extra genital en ambos géneros, dando como resultado, un modelo de respuesta sexual, incluía cuatro fases; excitación, meseta, orgasmo y resolución. Existen otros modelos funcionales que explican la respuesta sexual; modelo de Reich, modelo pentafasico de Bancroft, modelo trifásico de Helen Kaplan, modelo de Basson y modelo de Álzate. A partir del año 1986, Juan Luis Álvarez-Gayou Jurgenson, implementa dos fases más al modelo original de Master y Johnson; estímulo sexual efectivo y periodo refractario respectivamente, conocido como Modelo hexafásico de la respuesta sexual humana, el cual incluye una secuencia de eventos neuroendócrinos y psicológicos que dan certidumbre al proceso y a la identificación de las alteraciones que se presentan en cada fase, incluyendo un modelo de intervención que aborda los aspectos farmacológico, sistémico, psicodinámico y conductual, constituyendo una herramienta valiosa para la praxis médica y sexológica

THE IMPORTANCE OF MUNICIPAL COOPERATIVE RELATIONS FOR LOCAL DEVELOPMENT: THE CASE OF HATAY METROPOLITAN MUNICIPALITY
Authors: İbrahim ÇELEBİ Halil , TEK Murat
Published: July 2022

Kooperatif yapılar, bir işletme olarak düşünülse de ana hedefin kâr elde etmeme olması yönüyle özel sektör işletme modellerinden ayrılırlar. Kooperatifler bu özellikleri itibariyle yerelin “çok yönlü” kalkınabilmesi açısından önemli
alternatif modeller olarak karşımıza çıkmaktadır. Yani kooperatifler, yerel kalkınmaya salt ekonomik açıdan katkı sağlamanın ötesinde sosyal faydaya dönük eğitim, sağlık gibi alanlara yönelik de önemli etkide bulunan girişimlerdir.
Bu yönüyle kooperatifler yerel düzeyde insan gücü ve diğer üretim faktörlerini verimli ve planlı kullanabileceğimiz önemli yerel kalkınma aktörleridir. Kamunun yönetimine ilişkin giderek artan ‘yerelleşme' eğilimi içerisinde yerel
yönetimler önemli aktörler haline gelmektedir. Söz konusu yerel yönetimler içerisinde belediyeler özellikle yerel kalkınma açısından ön plana çıkan aktörler olmuştur. Bu doğrultuda kamu yönetimi reformu kapsamında yapılan yasal
düzenlemelerle belediyelerin görev ve sorumlulukları genişletilerek yeniden düzenlenmiştir. Belediyeler artık yerel kalkınma noktasında farklı aktörlerle işbirliği içerisinde olan daha dinamik kuruluşlar haline gelmiştir. Bu değişim
süreci içerisinde çalışmamız büyükşehir belediye yönetimlerinin yerel kalkınma stratejileri içerisinde kooperatifler yerel kalkınmaya nasıl katkıda bulunabilir sorunsalı etrafında şekillenmekte olup kooperatiflerin “dengeli kalkınma”
açısından oldukça işlevsel olabileceği iddiası da taşımaktadır. Bu amaca yönelik çalışmamızda belediye kooperatif ilişkisi yerel kalkınmaya etkisi bağlamında ele alınmıştır. Çalışmamız kapsamında Hatay’da faaliyet gösteren tarımsal
kalkınma kooperatifleri ve Hatay Büyükşehir Belediyesi’ne yönelik nitel sorulardan oluşan bir saha çalışması yapılmış, araştırmada elde edilen bulgular betimsel ve içerik analizi yöntemiyle yorumlanmıştır. Nitel analiz sonuçlarına
da dayanarak SWOT analizi yapılmış ve modele ilişkin güçlü ve zayıf yönler ortaya koyulmuştur. Hatay Büyükşehir Belediyesi tarafından başlatılan ve bizim “Hatay Modeli” olarak adlandırdığımız kooperatif belediyecilik ilişkisi tüm
boyutlarıyla ele alınmaya çalışılmış ve söz konusu modelimize ilişkin bir dizi öneriler ortaya koyulmuştur.

Published: July 2022

Piyanoda gerçekleştirilen müziksel performans; bilişsel, duyuşsal ve motor/kinestetik becerilerin tümüne dayanan oldukça karmaşık bir etkinliktir. Bir piyanistin müzikal performansı en doğru şekilde sergilemesi için gerekli hazırlıkların
dikkatli olarak yapılması gerekmektedir. Ezber çalmak da bu hazırlıkların bir parçasıdır. Ezber, ya da notalara bakmadan çalmak tüm seviyelerdeki piyanistler için hem eğitim hayatında hem de müziğin sergilendiği ortam ve konser
performanslarında oldukça önemlidir. Ancak doğru ezberin nasıl yapılması gerektiğini bilmemek öğrencilerin hem çalışma hem de icra sırasında kaygılı hissetmelerine ve dolayısıyla performansın bozulmasına neden olabilmektedir. Bu
araştırmada kaynak tarama yöntemi ile literatür taranmış, bellek, müzik bellek türleri, piyano eğitiminde müzikal eseri ezberleme sürecinin nasıl gerçekleştiği, piyano öğrencisinin hem eğitim hem de müzikal icra hayatı boyunca
karşılaştığı ezberleme sorunlarından bahsedilmiş, bu sorunların çözümüne dair önerilerde bulunulmuş ve araştırma sonuçlarına ulaşılmıştır.
THE PROCESS OF CONVERSION OF TURKS TO ISLAM AND THE EFFECT OF ISLAM ON TURKISH WOMEN'S PARTICIPATION IN SPORTS
Authors: TAZEGÜL Ünsal
Published: July 2022

Türklerin İslamiyet ile tanışmaları Hz. Muhammed zamanında olmuştur. Hz. Muhammed; Medine’ye gittikten sonra İslam’ı yaymak için dışa dönük bir siyaset izlemiştir. Birçok devlet başkanına ve bölgelerinde nüfuzlu olan kimselere tebliğ
mektupları göndermiştir. Bu mektuplardan bazılarının Türk büyüklerine gönderildiği ve mektubun “Türkçe” olduğu rivayet edilmektedir. Ancak Türkleri ciddi anlamda İslamlaştırma ve asimile etme çalışmaları Emeviler dönemine rastlamaktadır.
Yapılan bu çalışmanın amacı, Türklerin İslam dinini kabul etmeden ve kabul ettikten sonra, Türk toplumunda kadının önemini ve spor yapabilme düzeyini ortaya koymaktır. Yapılan bu araştırmada; tarama modeli kullanılmıştır. Tarama
modeli; geçmişte ya da halen var olan bir durumu, var olduğu şekliyle tanımlamayı amaçlayan bir yöntemdir. Konu ile ilgili yazılı kaynakların incelenmesi sonunda; İslam dinini kabul etmeden önce Türk toplumunda kadının saygın bir
yere sahip olduğu ve erkeklerle eşit haklara sahip olduğu görülmüştür. İslamiyet’in kabulünden önce kadın, her zaman erkeğinin yanında yer almıştır. Kimi zaman erkeğiyle birlikte omuz omuza savaşmış, kimi zamansa erkeğiyle birlikte
siyasi toplantılara katılarak fikirlerini belirtmiştir. Türklerde, kadın ve erkek arasındaki eşitliğin düzeyini gösteren en güzel örneklerden birisi; Göktürklerde, yayınlanan emirnamelerin Kağan ve Hatun namına ortak olarak imza
edilmesidir. Emeviler döneminde, Buhara’yı İslamlaştırmak için yapılan saldırılarda, Buhara Türk Melikesi Kabac Hatun tarafından yönetilmekteydi. Türk kadını; siyasi ve sosyal hayatta erkekle aynı haklara sahip olduğu gibi, spor
alanında da erkeğin yapabildiği bütün sporları yapabilmekteydi. Türk kadını; bir erkek gibi ata binebilmekte, erkek gibi ok atabilmekte ve hatta güreş bile yapabilmekteydi. Hatta bu spor dallarında kimi zaman erkeklerden daha üstün
başarılar göstermişlerdir. Yıllarca süren baskı ve işkenceler sonunda İslamiyet’in Türkler tarafından kabul edilmesinin ardından, Türk kadını toplum içerisinden yavaş yavaş silinmeye başlamıştır. Sosyal hayatta sahip oldukları
birçok özgürlüklerini kaybetmeye başlamışlardır. İslamiyet’in Türk toplumunda tamamen baskın olmasının ardından ise, kadın sadece erkeğin emir ve isteklerini yerine getirir hale gelmiştir. Bunun sonucu olarak, İslamiyet öncesinde
severek ve isteyerek yaptığı güreş, binicilik ve okçuluk gibi sporları artık yapamaz hale gelmiştir. Ayrıca İslamiyet’in kabulü ile Türklere ait birçok geleneksel spor yapılamaz hale gelmiştir.

Stability measure of multicriteria integer linear programming problem with a parametric optimality principle
Authors: Emelichev V. A. , Bukhtoyarov S. E.
Published: July 2022

In this paper, we consider a multicriteria integer linear programming problem with a parametric principle of optimality. Parameterization is realized by dividing the set of criteria into several disjoint groups (subsets) of criteria ordered by importance, with Pareto dominance within each group. The introduced parametric principle of optimality made it possible to connect such classical principles of optimality as lexicographic and Pareto ones. For the stability radius, which is the limiting level of perturbations of the parameters of the problem, not causing the appearance of new optimal solutions, the upper and lower estimations are obtained in the case of arbitrary Hölder’s norms in the criterion space and solution space. Some previously known results on the stability of the Boolean linear programming problem are formulated as corollaries.
Peculiarities of the Gaussian beam transformation in the optical scheme with an axicon and a biaxial crystal
Authors: Khilo N. A. , Ryzhevich A. A. , Balykin I. V. , Kazak N. S.
Published: July 2022

The transformation of a conical-type light beam by a biaxial crystal during propagation along one of its optical axes is herein investigated. The beam is formed by an axicon from the circularly polarized Gaussian input field. Depending on the position of the axicon either a Bessel beam or a combination of Bessel and conical beams falls on the crystal. The conversion coefficient from a zero-order Bessel beam to a first-order beam with phase dislocation is calculated. We show that if the angle of the beam cone and its diameter are large enough, then it is transformed into a field that is a first-order BesselGaussian beam with high accuracy. At the same time the conversion coefficient is close to 1. The case of a small cone angle of an incident Bessel beam is also investigated. In this case the efficiency of transformation significantly depends on the type of the spatial spectrum. At a small cone angle, the shape of the spatial spectrum is determined by the diameter of the incident Gaussian beam. Namely, as the diameter decreases, the beam spectrum changes from annular to close to Gaussian, passing through an intermediate form in the form of a superposition of these two profiles. The influence of the spatial spectrum is the conversion coefficient decreasing with a decrease of the of the ring component contribution to the spectrum. In this case, the conversion coefficient is always higher than for a scheme without an axicon when a Gaussian beam falls on the crystal. Consequently, the introduction of even a small conicity into the beam makes it possible to increase the field transformation coefficient. It can be implemented, for example, using a scheme with two axicons having close angles of a ray deflection. The results obtained are also of practical interest, in particular, for the development of conical-type laser emitters with a small cone angle for long-range reconnaissance and optical communication in free space.

Published: July 2022

The genes of the neurotransmitter systems of the brain play a significant role in the formation of the psychological properties of a person. The dopaminergic system is one of the leading systems influencing the manifestation of individual psychological characteristics and the development of anxiety and depressive disorders. The association of polymorphic variants of the dopaminergic system genes with the psycho-emotional status of a person was analyzed using the molecular genetic analysis. The study involved 1454 representatives of the Belarusian population. The genotypes of 167 employees of the special forces of the Ministry of Internal Affairs of the Republic of Belarus and 235 highly skilled athletes were studied as the groups that were supposedly more stress-resistant. The opposite group consisted of 534 patients of the Republican Scientific and Practical Center for Mental Health with personality disorders and deviant behavior. The population control group included 518 volunteers representing the population of Belarus without known pathologies. As a result of the psychological testing, the groups with low and high emotional stability were identified by the quartile method. Genetic testing of groups with 11 polymorphic variants of 5 genes of the dopaminergic system made it possible to identify informative genetic markers of a person’s psycho-emotional status. The most significant polymorphisms were rs4680 and rs165599 of the COMT catechol-O-methyltransferase gene, rs1611115 of the dopamine-metabolizing enzyme dopamine-β-hydroxylase gene DBH, and rs6275 of the type 2 dopamine receptor gene DRD2. The results obtained can be used for preventive diagnostics of disorders in the psycho-emotional sphere, as well as for the development of programs for correction of borderline states, deviant and delinquent behavior, as well as mental illness.

Antimicrobial metabolites of bacterial strain B. amyloliquefaciens BIM B-1125, the basis of Bacto-health preparation, demonstrating antagonism against the representatives of the opportunistic microbiota of valuable fish species, were isolated and characterized. Extracellular localization of antimicrobial compounds was established; their stability is shown in the temperature range of 50–100 °С and in the pH range of 2–10. The lipopeptide nature of antimicrobial metabolites was shown using thin layer chromatography. The mass spectrometric analysis of the active fraction confirmed the production of lipopeptide metabolites belonging to the iturin and surfactin families (iturin A, iturin A4, iturin A6-A7 isomers, surfactin A, surfactin C, and surfactin B isomers).
Role of the cells of the system of mononuclear phagocytes and regulatory T-lymphocytes in the formation of the state of immunosuppression in sepsis
Authors: Titov L. P. , Trusevich M. O. , Gorbich Yu. L.
Published: July 2022

Sepsis still represents one of the leading causes of death in hospitalized patients worldwide, and its incidence is increasing. Changes in the relative and absolute blood levels of monocytes, dendritic cells, myeloid suppressor cells, and regulatory T-lymphocytes in the blood of patients with sepsis and septic shock were studied on the 3rd–4th day after diagnosis in order to identify the stage of immunosuppression. 33 patients with sepsis (19 men and 14 women, age 57.1 ± 19.9 years) and 6 patients with septic shock (2 men and 4 women, age 49.3 ± 19.6 years) were examined. The control group included 30 healthy donors. Subpopulations of monocytes, dendritic cells, myeloid suppressor cells, and Treg cells were determined by flow cytometry. A significant decrease in HLA-DR expression on monocytes, a decrease in the relative content of classical monocytes, myeloid and plasmacytoid dendritic cells, an increase in the percentage of intermediate monocytes and G-MLSC CD15+, an increase in the absolute content of Treg cells in patients with sepsis and septic shock were revealed. The revealed functional defects and shifts in the composition of the leukocyte population indicate the development of the stage of immunosuppression in patients with sepsis.

A change in the external conditions leads to restructuring the adaptive behavior of animals, their motor activity, which makes it possible to use ethological properties to assess the body state in different production modes. In this regard, there is an urgent need for total monitoring of the health status and activity of pigs. The article contains the results on the effect of different-type stress on the pig stock during the rearing period under on-farm conditions. The studies were carried out at the pig farm of the State Enterprise “ZhodinoAgroPlemElita” in the groups of lactating sows kept under identical conditions, based on monitoring by year seasons in the following algorithm: complying with comfort criteria, reducing the stress impact, improving the health status, increasing the productivity. The predominant activity types of sows under on-farm conditions have been studied. It has been found that the predominance of the comfort activity among other types contributes to the offspring viability. Types of the activity of sows are inextricably linked to motivations, that is, the desire of animals to satisfy the priority needs of the body. Examples of high and low food motivation have been identified. Extra space, physical and visual barriers to protect more submissive sows have been found to have a positive effect on reducing overall aggression.
Electromagnetic shield design based on pseudooval scattering elements for information protection from leakage via the electromagnetic channel
Authors: Savanovich S. E. , Borbotko T. V.
Published: July 2022

The results of the study of the values of the reflection coefficients and the effective scattering surface of the developed design of the electromagnetic radiation screen in the frequency range of 2…12 GHz are considered. The structure consists of a layer of moisture-containing pseudo-oval scattering elements with linear dimensions of 1…4, 1…2 and 10…20 mm, which is placed between two layers of polyurethane sealing mastic. The use of pseudo-oval elements with linear dimensions of 1…4 mm containing solutions made on the basis of a 20 % solution in the developed electromagnetic radiation screen design allows reducing the values of the reflection coefficients of electromagnetic radiation at frequencies 4.2…6.5 and 1.0…4.1, 8.0…12.0 GHz. The formation of a screen design based on elements with linear dimensions of 1…2 and 10…20 mm, impregnated with a 20 % sodium chloride solution, leads to a decrease in the values of reflection coefficients in the frequency range of 2…12 GHz. It is established that the values of the effective scattering surface of ground objects in case of placing or fixing of the specified design variant of the electromagnetic radiation screen on their surface are 0.6…24.0 m2 in the frequency range of 2…12 GHz. This makes it significantly difficult to obtain reliable information about the location and characteristics of ground objects in the frequency range under consideration.

The article contains the initial operation algorithms of adaptive antenna arrays, conclusions of equivalent processing algorithms and an equivalent block diagram of the generalized LMS algorithm. Equivalent forms of writing the operation algorithms of adaptive antenna arrays and their parameters are also presented in tabular form. Of particular interest is the equivalent operation algorithm in the case of the SMI algorithm, which differs most from the LMS algorithm. Equivalent algorithms differ only by the scalar convergence coefficient and the matrix normalizing factor. For LMS-Newton, SMI, and RLS algorithms, the matrix normalizing factor is the same, it is determined by inverting the estimation of the correlation matrix of input signals and reduces the dependence of the characteristics of the algorithms on the parameters of the correlation matrix. The scalar convergence coefficient of equivalent algorithms in the case of SMI and RLS algorithms depends on the iteration number and tends to zero for the SMI algorithm and to some non-zero value for the RLS algorithm. The dependence of the convergence coefficient on the iteration number makes it possible to optimize the characteristics of the algorithms at the transition stage. The tendency of the convergence coefficient to zero in the case of the SMI algorithm makes it effective only for stationary input signals. The non-zero steady-state value of the convergence coefficient in the case of the RLS algorithm allows its effective use in a non-stationary environment.

Published: July 2022

In the course of the work, the parameters of respiration of mitochondria of brain homogenates and the content of ATP synthase in rats with cerebral ischemia and under conditions of administration of ω-3 polyunsaturated fatty acids were studied. ω-3 polyunsaturated fatty acids have an anti-inflammatory effect due to their incorporation into the phospholipid layer of cell membranes of monocytes, leukocytes, endothelial cells, which is accompanied by a decrease in the production of inflammatory mediators and a decrease in leukocyte adhesion to the endothelial wall. Polyunsaturated fatty acids regulate vascular tone and prevent vascular vasoconstriction under the influence of catecholamines, which causes a moderate vasodilatory effect. ω-3 polyunsaturated fatty acids have a corrective effect on mitochondrial respiration, their beneficial effect on the structures of the hippocampus in conditions of subtotal cerebral ischemia and a lesser severity of manifestations of neurological deficit, compared with the group without their administration, are noted.

Consideraciones anestésicas en los pacientes con presencia de puentes intramiocárdicos. The milking Syndrome.
Authors: David Peral Sanchez  , Elena Porcar Rodado
Published: July 2022

Los puentes intramiocárdicos son aquellos segmentos de las arterias coronarias que se introducen en el espesor del músculo miocárdico, en lugar de transcurrir por el epicardio durante todo su trayecto. Este hecho condiciona la compresión y dilatación de estos segmentos durante el ciclo cardíaco, lo que, angiográficamente, se considera fenómeno milking. Los pacientes suelen ser asintomáticos y tener buen pronóstico a largo plazo, aunque pueden presentar eventos isquémicos, arritmias cardíacas e incluso muerte súbita, precipitados sobre todo por episodios de taquicardia o estrés. Suele ser un hallazgo casual al realizar una coronariografía, o un TAC multidetector, que es la prueba de elección. El tratamiento se basa en el control de la frecuencia cardíaca mediante betabloqueantes o calcioantagonistas, aunque pueden llegar a ser necesarias terapias como la angioplastia o la cirugía. Presentamos el manejo de un paciente con esta dolencia y discutimos algunos aspectos interesantes desde el punto de vista anestésico.
Film-Induced Effects and Intention to Visit: The Intervening Role of Country Image of South Korea
Authors: DELA CRUZ Jae Ann , LACAP Jean Paolo
Published: July 2022

In the realm of film tourism, film-induced effects have been identified to be integral factors in the formation of intentions of a viewer to visit a destination. Grounded on the stimulus-organism-response (SOR) model, the present study aims to examine how Korean film-induced effects (visual, vocal, and celebrity) influence viewers’ intention to visit South Korea. Furthermore, it investigates the intervening role of country image on the relationship between film-induced effects and intention to visit South Korea. The respondents were Filipino viewers of Korean movies and dramas, and they were selected using the river sampling technique. Using variance-based (partial least squares) path modelling, the results revealed that film-induced effects significantly and positively influence viewers’ intention to visit South Korea, and visual effect largely contributes to the formation of these intentions. Country image was also found to significantly influence intention to visit, and act as a mediator on the link between film-induced visual effect and intention to visit South Korea. The present study addresses the gap in literature as it showed the indirect role of country image on the relationship between film-induced visual effect and intention to visit South Korea.

Sweet corn (Zea mays L. saccharata) is a horticultural product widely consumed by Indonesian people because of its sweetness. Corn requires sufficient nutrients to grow and produce the optimal yield so that the fertilization is a determining factor in corn cultivation. Bio-organomineral fertilizer (BIOM) is a fertilizer that combines mineral, organic, and biological elements (microorganisms). This study aims to examine the effect of BIOM on growth of sweet corn, nutrient uptake, and soil fertility. Experimental design used in this research was Randomized Block Design (RBD) with nine treatments and three replications which consist of treatments control; 1 NPK; ½ BIOM; 1 BIOM; 1 NPK + ½ BIOM; 1 NPK + ¾BIOM; 1 NPK + 1 BIOM; ¾NPK + 1¼BIOM; and ¾NPK + 1½BIOM. Effect of BIOM fertilizer at 100% dosage significantly increased the plant height, stem diameter, and canopy diameter compared to the control. BIOM fertilizer had a significant effect on the N uptake, total N, P-potential, P-available, K-potential, and K- exchangeable. The fertilizer is able to provide positive results on the growth of sweet corn, so it’s more effective for the availability of nutrients needed by sweet corn plants.
