Published: October 2021

Aim: We aim to determine the preoperative anxiety levels of
patients with open-heart surgery and examine the relationship between
anxiety levels and postoperative complications. Material and
Methods: In our prospective study, 200 patients who will undergo
open-heart surgery preoperative anxiety levels were measured using the
Hamilton anxiety scale (HAM-A). Anxiety levels and the development of
complications were investigated. Results: Preoperative anxiety
was more common in females (p=0.001). The length of stay in the
intensive care unit (p=0.006) and the hospital stay (p=0.005) were found
to be longer in patients with high anxiety. It was observed that high
preoperative anxiety severity increased the risk of developing
postoperative complications (p=0.000024). Conclusion: We can
say that preoperative anxiety, which is not considered very important,
is seen more frequently than expected for patients who will undergo
open-heart surgery. In our study, it was observed that high anxiety
levels increased the risk of postoperative complications.

On refined generalised quasi-adequate transversals
Authors: Kong Xiangjun , Wang Pei
Published: October 2021

Some properties and characterizations for abundant semigroups with
generalised quasiadequate transversals are explored. In such semigroups, an
interesting property [?a,b ? Re1S, VSo(a) ? VSo (b) ? 0 ? VSo (a) = VSo
(b)] is investigated and thus the concept of refined generalised
quasi-adequate transversals, for short, RGQA transversals is introduced. It
is shown that RGQA transversals are the real common generalisations of both
orthodox transversals and adequate transversals in the abundant case.
Finally, by means of two abundant semigroups R and L, a spined product
structure theorem for an abundant semigroup with a quasi-ideal RGQA
transversal is established.
Laser textured novel patterns on Ti6Al4V alloy for dental implants surface improvement
Authors: Dabbagh Gholam Reza , Sadrnezhaad S. K. , Shoja Razavi Reza , Nourbakhsh Amir Abbas , Hassanzadeh Nemati Nahid
Published: October 2021

Creating laser texture on dental implants is a novel method for accelerating osseointegration and prolongation of lifespan. The purpose of this research was twofold: (1) Creating intersecting lines pattern with different angles (0°, 15°, 30°, 45°, 60°, 75°, and 90°) on the surface of Ti6Al4V, using pulse Nd:YAG laser with a wavelength of 1064 nm and a pulse length of 170 ns and (2) comparing optical and SEM images, EDS analyses, contact angles (CAs), and surface free energies (FEs) for different intersecting lines angles. CA and FE depended on the intersecting lines angle according to Y=Y0+Asin(xB+C), where Y is the CA or FE; x is the intersecting lines angle; and Y0, A, B, and C are constants. Oxygen was present on all samples. The lowest CA and the highest FE occurred at 60° intersecting lines. FE was independent of minor changes in the microgrooves' depth, intersections' number, and the number of texture lines.
Consolidation of thermoplastic coatings by means of a thulium-doped fiber laser
Authors: Wittmann Alexander , Heberle Johannes , Huber Florian , Schmidt Michael
Published: October 2021

Thermoplastic polymers such as polyamide 12 (PA12) are of great interest for functional coatings in industry due to their good material properties (e.g., chemical and wear resistance and biocompatibility). In order to provide a high local selectivity of polymer deposition and to shorten the process chain, a laser-based coating process represents a promising approach for generating functional coatings. In this work, a laser-based coating process for PA12 powder on stainless steel substrates is investigated experimentally by using a thulium-doped fiber laser with a wavelength of 1.94 μm. Due to the higher inherent absorption of the laser radiation in the powder material, a thulium-doped fiber laser is more appropriate for processing PA12 powder in comparison to more common near-infrared laser beam sources with wavelengths around 1 μm. The influence of the main process parameters (laser power, scanning speed, hatch distance, and substrate temperature) on the resulting coatings was evaluated. For this purpose, optical microscopic analyses were performed to characterize the coating surfaces and cross sections in terms of possible defects. In order to assess the adhesion between the coating and the substrate, cross-cutting values were determined. On the basis of the quality characteristics regarding the coating surface, a process window was determined to produce a closed melting film, which fully covers the metallic substrate. By an adjustment of the scanning speed (5 mm/s) and line overlap (50%/62.5%), a broadening of the process window could be achieved. An additional substrate heating (T ≥ 90°C) is an appropriate strategy, which enlarges the size of the process window significantly. Optical microscopy analyses and cross-cutting tests verified the suitability of a thulium-doped fiber laser for processing dense PA12 coatings with an adequate adhesion to the stainless steel substrate. The substrate temperature is a decisive process parameter to obtain a homogeneous morphology and to further improve the adhesion between the metallic substrate and PA12 layer.

Interacciones de los instructores y los aprendices de los pueblos indígenas del Centro de Producción y Transformación Agroindustrial de la Orinoquia en la formación profesional integral
Authors: Arias Mejía John Rafael
Published: October 2021

El presente artículo presenta los resultados del proyecto de investigación Interacciones de los instructores y aprendices de los pueblos indígenas del Centro de Producción y Transformación Agroindustrial de la Orinoquia en la Formación Profesional Integral cuyo objetivo general con- sistió en analizar las diferentes interacciones entre los instructores del Centro de Producción y Transformación Agroindustrial de la Orinoquia (CPTAO) y los aprendices que pertenecen a di- ferentes pueblos indígenas que habitan el departamento del Vichada, a través de un diseño me- todológico cualitativo que incluyó la realización de un diagnóstico y de varios grupos focales. La investigación pretendió brindar a los instructores herramientas para orientar con calidad y pertinencia los procesos de la Formación Profesional Integral, al tiempo que permitió que los aprendices indígenas pudieran tomar un rol mucho más activo en la etapa lectiva y productiva que les ofrece el SENA y los coformadores aliados. Los resultados de la investigación posibilitaron que los aprendices se autorreconocieran como pertenecientes a alguno de los pueblos indígenas del Orinoco, facilitando con ello las interacciones entre los actores de la investigación en el año 2020. De igual manera, se lograron identificar los lugares de origen de los instructores y aprendices, los ambientes de aprendizaje y los equipos especializados del Centro, así como los problemas de conectividad del territorio y el enfoque de pluralidad y diferencial de la entidad. La investigación permitió, también, caracterizar los procesos de desarraigo cultural y los sentires y percepciones de aprendices e instructores que participan de la Formación Profesional Integral, desde donde se asume a los actores de la formación como seres humanos, permitiendo conocer elementos que inciden directamente en la construcción de tejido social en Colombia.
Limitación de Derechos y Garantías Fundamentales en época del COVID-19. “Una posible afectación a los principios y contrapesos democráticos”
Authors: Galvis Martínez Juan Carlos
Published: October 2021

A raíz de la propagación mundial del virus 2019-nCoV o COVID-19, se generó una crisis mundial, y Colombia no es caso aparte, pues después de la declaratoria como pandemia por la OMS, el 11 de marzo de 2020 (Marchiori & Tobar, 2020), el Gobierno Nacional, días después, por medio del Decreto 417 de 2020, declaró el Estado de Excepción por la Emergencia Económica, Social y Ecológica. Paso seguido ordenó el confinamiento de los ciudadanos mediante Decreto 457 de 2020, y la extendió con el Decreto 531 de 2020. Muchas críticas han implicado estas decisiones, entre los juristas y estudiosos del derecho, resaltando a los constitucionalistas y administrativistas. Las formas en la toma de decisiones del ejecutivo, tienen una razón de ser y cuentan con límites y finalidades. Varias han sido las intervenciones jurisprudenciales en las cuales se han evidenciado los requisitos de una declaratoria de los Estados de Excepción. Para el caso que nos ocupa, el Estado de Emergencia Económica, Social y Ecológica, que su declaratoria y las medidas encaminadas a su control debe ser por decretos legislativos, mas no por las otras modalidades que existen bajo las potestades extraordinarias del Gobierno Nacional. Por ello, al observarse que se han tomado medidas como manejo de la crisis producida por el COVID-19, en las que se han restringido derechos y garantías fundamentales, se atisba una grave inconstitucionalidad en las decisiones, que puede servir como precedente para el futuro y para permitir que se violenten los contrapesos que impuso la Constitución, como salvaguarda de los principios democráticos del Estado Social y de Derecho.

Published: October 2021

El objetivo de la investigación es analizar las representaciones sociales que estudiantes y docentes tienen con respecto a la Cátedra de Estudios Afrocolombianos. La investigación se basa en el paradigma interpretativo, el enfoque cualitativo y el método de estudio de casos. Las técnicas e instrumentos utilizados son el análisis de contenido y la matriz categorial, las técnicas interactivas y el mural de situaciones, y la entrevista estructurada con una guía de preguntas. Los resultados identificados indican un desconocimiento de las representaciones sociales que estudiantes y docentes tienen con respecto a la Cátedra, ya que éstas representaciones guardan muy poca relación con lo analizado en la fundamentación teórica de la misma, toda vez que aún existen confusiones conceptuales, apoyo a ideas de superioridad étnica y cultural y desconocimiento de la importancia de la interculturalidad para Colombia.

Published: October 2021

Objectives: The aim of this study was to compare the rate of parasitism and intestinal parasitism profiles of children who live in relatively proximal communities across the 5 municipalities of the Barranquilla metropolitan area, Colombia.Methods: In total, 986 fecal samples from children aged 1 to 10 were analyzed using a direct method (physiological saline and lugol) and the zinc sulfate flotation technique. A comparative analysis of the parasitism profiles between sampling locations (7 schools and 3 health centers providing growth and development services) was conducted using principal component analysis (PCA). The presence of Taenia solium antibodies was evaluated by the enzyme-linked immunosorbent assay method in 269 serum samples from the same group of children.Results: The overall prevalence of intestinal parasitism was 57.6% (range, 42.1%–77.6%) across the sampling areas. The prevalence of helminthiasis was between 4.1% and 23.7%, and that of intestinal protozoa was between 38.2% and 73.5%. PCA showed that the parasite profiles of each sampling location shared no common characteristics. A total of 3.0% of the serum samples were positive for T. solium antibodies.Conclusion: The intestinal parasitism profiles between relatively proximal sampling locations with similar geographic conditions were vastly different, indicating the need to study each small ecological niche on a localized scale to develop more cost-effective interventions for controlling intestinal parasitism.

Los cambios recurrentes del entorno generan incertidumbre e inestabilidad a las organizaciones, tanto para organizaciones con ánimo o sin ánimo  de lucro, en razón de ello durante décadas las organizaciones con ánimo de lucro han mirado de manera estratégica como crecer y mantenerse en el mercado a través de identificar la situación actual y proyección hacia al futuro. En igual sentido, las organizaciones sin ánimo de lucro en los últimos años vienen utilizando esa mirada  estratégica como medio para ser mucho más efectivas en su gestión y sostenibilidad, aunque su fin último es de carácter social. El objetivo de este documento es presentar los hallazgos del estudio realizado sobre planeación estratégica en Juntas de Acción Comunal, ubicadas en la ciudad de Barranquilla- Colombia. Con este propósito se hizo revisión bibliográfica sobre el tema; así mismo se aplicó cuestionario a los presidentes de 50 juntas de juntas de acción comunal, cuyas respuestas fueron tratadas mediante un análisis descriptivo. Los principales resultados reflejan que la perspectiva estratégica es un tema muy incipiente en las organizaciones estudiadas, en tanto sus líderes, solo piensan el día a día y adolecen de las competencias gerenciales. Presentan baja capacidad estratégica para lo interno y poder establecer alianzas urgentes y necesarias para la sostenibilidad de las organizaciones. En conclusión, la perspectiva estratégica representa un desafío para las organizaciones en estudio y desde luego  una herramienta para dimensionar estas organizaciones a largo plazo en pro del desarrollo de los territorios.

FUNDAMENTOS HISTÓRICOS Y JURÍDICOS PARA APLICAR LA TEORÍA DE LA INMISIÓN EN LA LEGISLACIÓN CIVIL COLOMBIANA.
Authors: Beltrán Agamez Katerine
Published: October 2021

La teoría de las inmisiones es un límite de la propiedad que nos viene directamente del derecho clásico romano, en este periodo no se desarrolló un concepto como hoy, más bien se le da  aplicabilidad al principio: Cada quien puede hacer en lo suyo lo que le parezca, siempre y cuando no afecte el derecho ajeno. Este principio fue recogido por Bello e incorporado al código civil, pero pese a esto, fue olvidado dando paso a otras bases interpretativas que se centran en otros modelospolíticos, sociales y culturales distintos a los que sirvieron de base a nuestra legislación civil. Se necesita estudiar la base histórica de esta doctrina para poder elchar mano oportunamente de ella.

Armenia has adopted chess in primary school programs since 2011, and different types of research have been conducted to evaluate the effectiveness of this implementation. One of the questions to be addressed after chess adoption is: “What are the main and contextual factors of the effectiveness of that implementation?”, or “How these factors have been changed?”. The article tries to answer those questions by conducting correlational research on a representative sampling of Armenian students, their parents and teachers.
OVERCOMING OF AGGRESSIVE BEHAVIOR OF PRIMARY SCHOOL CHILDREN THROUGH FAIRY TALE THERAPY
Authors: Samvel Asatryan Miopap
Published: October 2021

The article provides definitions of aggression, the causes of its occurrence, as well as fairy tale therapy as a means of overcoming aggressive manifestations. A research was conducted to study the psychological characteristics of the aggressive behaviour of younger schoolchildren. The formative linear experiment was used. The method for diagnosing aggression Bass-Darky and Rosenzweig's test of measuring the aggressiveness were carried out. In the aggressive behavior of primary school children is dominated by negative and indirect aggression; verbal and physical aggression are moderately manifested; auto-aggression, insult and suspicion are weakly expressed. More than half of primary schoolchildren have a high level of aggressiveness. In the vast majority of pupils, aggressive reactions are directed to the environment, that is, the orientation of aggression is extrapunitive. In about a quarter of pupils, the orientation of aggression is impunitive, for what happened they attribute the blame to the situation. The weakest expression has the intrapunitive orientation of aggression, when the child considers himself responsible for the event. To overcome the aggressive manifestations of primary schoolchildren, a training program was used, in which therapeutic tales and training exercises were included. If before applying a training program for overcoming agressiveness, aggressive reactions of most younger schoolchildren were directed at others, and they considered others to be responsible for solving the problem, then after implementing the training program the results of the retest show that there has been a sharp increase in the rate of intrapunitive aggression. That is, children began to count, that the solution of the problem depends more on the person, and in case of failure, the person should blame not the other, but own identity. Therapeutic fairy tales are an effective way to overcome the aggressive behaviour of children in educational institutions.

Investigation of the influence of manual ventilation-controlled respiration on right ventricular pressure-volume loops and echocardiographic variables in healthy anesthetized dogs
Authors: Yuchi Yunosuke , Suzuki Ryohei , Teshima Takahiro , Matsumoto Hirotaka , Koyama Hidekazu
Published: October 2021

OBJECTIVE

To evaluate the influence of manual ventilation-controlled respiration on right ventricular (RV) pressure-volume loop–derived and echocardiographic variables in dogs.

ANIMALS

8 healthy, anesthetized Beagles.

PROCEDURES

In a prospective experimental study, pressure-volume catheters were percutaneously inserted into the right ventricle of each dog, and manual ventilation was performed; RV pressure-volume loop (hemodynamic) data and conventional echocardiographic variables were assessed. Two-dimensional speckle tracking echocardiography–derived RV strain (RVS) and RV systolic strain rate (RVSR) were obtained with RV free wall–only analysis (free wall) and RV global analysis (RVGA; interventricular septum). Variables were compared between end-inspiratory and end-expiratory phases of respiration by statistical methods. Multiple regression analysis was used to assess associations between selected hemodynamic and echocardiographic variables.

RESULTS

The RV pressure significantly increased, and RV volume, stroke volume, tricuspid annular plane systolic excursion, RV fractional area change, peak myocardial systolic velocity of the lateral tricuspid annulus, and RV free wall only–assessed RVS and RVSR significantly decreased in the inspiratory phase, compared with the expiratory phase. There were no significant differences in end-systolic elastance or RVGA-assessed RVS or RVSR between respiratory phases. The RVGA-assessed RVSR was significantly associated with stroke volume and end-systolic elastance.

CONCLUSIONS AND CLINICAL RELEVANCE

Specific RV echocardiographic variables were significantly affected by respiration. In contrast, RVS and RVSR determined with RVGA were not affected by respiration and were associated with hemodynamic indicators of RV contractility.

Published: October 2021

Aim. To develop the unified method of the HPLC analysis of loratadine, which can allow obtaining reliable and reproducible results of the studies of pharmaceuticals and biological matrices for monitoring the treatment effectiveness.Materials and methods. The HPLC analysis was performed on a “Milichrome A-02” microcolumn liquid chromatograph under the following conditions: a reversed-phase variant, 2 × 75 mm column filled with a non-polar sorbent Prontosil 120-5 C18 AQ, 5 μm; the mobile phase in the mode of a linear gradient – from eluent А (5 % of acetonitrile and 95  % of a buffer solution) to eluent B (100 % of acetonitrile) for 40 min. The flow rate of the mobile phase was 100 μL/min; the injection volume was 4 μL. The multichannel detection of the substance was carried out using an UV-detector at 210, 220, 230, 240, 250, 260, 280 and 300 nm; the optimal value of the column temperature was 37 – 40 °С, and the pump pressure was 2.8 – 3.2 MPa.Results and discussion. As a result of the studies performed, the retention parameters of loratadine and spectral relationships were determined using the unified HPLC method. This made it possible to include the results obtained in the database for the identification of antihistamines in the therapeutic monitoring of the treatment with an individual drug or in the complex treatment of allergic reactions. The development of the quantitative determination of loratadine by HPLC on model solutions using various concentrations of the drug was carried out. The content of loratadine was determined by the equation S = 1.14 × 10-3C – 0.50 × 10-4; the correlation coefficient was 0.9998. It was found that the relative standard deviation RSD did not exceed 0.93 % when analyzing loratadine in the model solutions by HPLC.Conclusions. The identification and the quantitative determination of loratadine by the unified HPLC method have been conducted. The method allows obtaining reliable and reproducible research results. The results of the studies can be recommended for implementation in the practice of forensic bureaus, toxicological centers, and clinical laboratories.

This work addresses the case of Madrid, a city that has first‑rate heritage assets in its metropolitan periphery, whose better touristic use would help to mitigate the negative impact on the capital, while contributing to the economic and social development of the periphery. In the research, a dynamic methodological approach was applied with four complementary analysis planes: documentary and networks, qualitative, quantitative and participatory processes. The results show the need to adopt cultural management and tourism planning strategies aimed at rebalancing visitor flows. The activation of the neighbors themselves is revealed as an especially valuable resource to strengthen proximity, experiential and more sustainable tourism. The The impact of Covid‑19, on the one hand, and the declaration of Paseo del Prado and El Retiro as World Heritage Sites, on the other, have made this situation even more topical.

Self‑perception of individuals has been explored from various perspectives in the social scienc‑ es; although, very few studies have focused on self‑perception of individuals as tourists. By using semi‑ ‑structured interviews, this research aimed at approximating a vision of a tourist’s self‑perception indestina‑ tions defined as cultural. The activities of tourists who visit cultural destinations are in every way similar to other tourists although they perceive themselves differently. Hence, the results of the study show that the cultural tourist’ self‑perception depends on multiple factors, that it is not necessarily negative for them to perceive themselves as typical tourists but that it is not an immediate self‑perception

The current situation of tourism has derived towards tourists demanding authentic and unique tourism experiences. However, providing tourists with such experiences is not a simple task for tourism firms and destinations. The literature suggests that gastronomy, as part of the culture of the communities tourists visit, has the potential to offer the uniqueness and authenticity demanded. We therefore build on food tour‑ ism literature to identify its potential as a motivational factor as well as an enhancer of tourists’ satisfaction. The aim of this study is to analyzs the characteristics of those visitors most likely to be interested in the consumption of typical local gastronomical products when visiting the Canary Islands. Consequently, in the present study we identify the profile of tourists for whom gastronomy plays an essential motivational role when travelling. To do so, we have used the answers given by tourists on the Tourism Expenditure Survey and conducted regression analysis. The results suggest that there are differences in the socio‑demographic profile of gastronomic tourists to Canary Islands, their motivations and also the characteristics of their trips. The conclusions of the study indicate that the segment of tourists motivated by gastronomy is considerable in the Canary Islands and it is necessary to improve the satisfaction of these tourists since they are more likely to spend more in the destination than the average visitor.

In the last few decades, branding is an important part of marketing tourism destinations. Tour‑ ist destinations started to be seen as companies and started to use the brand as a way to attract and retain visitors. The brand is based on a perspective of value creation acting as a differentiation strategy in an increasingly competitive market. In this context, this study presented here sought to understand how the regional entity of Tourism in Porto and Northern Portugal has developed its marketing through branding. In methodological terms, in a first part, there is an analysis of the literature on the concept of brands, and in a second part, the strategies adopted by the target entity of our study were analysed. As main conclusions, it was found that this entity sought to create its own brand, aggregating all anchor strategic products and complementary products, from its sub‑regions with a view to promoting its natural and heritage resources, and to convey the idea of a glam‑ orousa cosmopolitan destination with history and tradition.

We present a bibliometric and social network analysis of the Brazilian field of tourism, taken as the articles of 16 Brazilian tourism journals. Utilizing keywords, we describe and evaluate its trajectory (1990‑2018), with focus on the cultural tourism cluster. We study the authorship (authors, institutions and geographic distribution), journals (dispersal of publication), impact and intellectual structure of the cluster. It is clearly delimited, and includes “expected” keywords that orbit around cultural tourism, culture and heritage. Authorship is relatively fragmented; there is an overrepresentation of the Northeast Region of Brazil. In the references, there is a distinct social sciences orientation; there are relatively few authors and texts concerned with cultural tourism as a market segment. Margarita Barretto’s dominance and centrality in the intellectual structure is clear. Concerning the impact, the cluster has an average of actual citations per article just below that verified for the field.
Nuevas relaciones entre cultura, turismo y territorio en el contexto de la posmodernidad
Authors:   Universidad Nacional de La Plata (Argentina), Moscoso Florencia Viviana
Published: October 2021

Faced with new dynamics and new views of the socio‑cultural context of tourism, this essay seeks to carry out a brief reflection and analysis on the relationship between cultural identities and postmodern visions of tourist territories. The aim is to study the social practice of tourism in articulation with its actors, spaces, appropriations and larger social processes. In order to achieve the purpose of this essay, revision and critical analysis of pertinent bibliography on the subject was used, confronting different perspectives and views. Basic constructs built around the concept of cultural identities and their relationship with place and tourism are likewise questioned. Meanwhile, within the field of tourism research, models continue to be replicated where tourism is classified as a predator and banaliser of the local culture. Research along the axis of tourism and cultural geography is advocated to contemplate the new complex concptualisations within the triad of tourism, culture and territory.

Purpose. Тo analyze clinical efficacy of the surgical treatment of previously operated strabismus using limbal incisions which are lengthening the conjunctiva and Tenon's capsule. Material and methods. The study included 440 patients (440 eyes) with previously operated strabismus at the age of 4 to 68 years old. The main group included 240 patients (240 eyes) who underwent strabismus surgery by limbal approach; the control group included 200 patients (200 eyes) who underwent surgery by paralimbal conjunctival approach. Horizontal strabismus occurred in 146 patients (60,8%) in the main group and in 158 (79%) in the control group. Horizontal strabismus in combination with vertical strabismus was found in 94 patients (39.2%) in the main group and in 42 patients (21%) in the control group respectively. The following approaches were applied: Y-shaped limbal approach, T-shaped incision of the conjunctiva, lower limbal peritomy, circular limbal approach with an additional horizontal incision towards the muscle being strengthened. Results. Good cosmetic result in the main group was achieved in 94.7% of cases, in the control group in 87% of cases, р<0.001. Re-surgery in the long term period was required for 39 patients (19.5%) in the control group and 14 patients (7%) in the main group, р<0.001. Conclusion. Limbal approaches performed to lengthening the conjunctiva and Tenon's capsule on the side of the weakened muscle and shortening on the side of the muscle being strengthened, are enhancing the effect of recession and resection, thereby contributing to the achievement of the state of orthotropy in 83% and have a good cosmetic result in 94.67% of cases. Key words: limbal conjunctival approaches, limbal conjunctival incisions, strabismus, children.
