Convergências entre as políticas territoriais no Brasil e o desenvolvimento como liberdade
Authors: De Faria Balbino Tomás , Narciso Shiki Simone de Faria , Melo Silva Gustavo
Published: February 2021

As ideias em torno do desenvolvimento se fundamentam em diversas perspectivas e estruturas no campo político e científico. Um fator comum encontrado pelos teóricos desenvolvimentistas é que o processo de transformação de uma sociedade acontece de forma multidimensional e é impactado por uma série de variáveis. Amartya Sen é um dos principais economistas a fundamentar uma teoria política de desenvolvimento  multidimensional, pautada na ideia de que o desenvolvimento deve ser entendido como um processo de expansão das capacidades humanas, criando assim o termo “desenvolvimento como liberdade”. Dentro do grupo de perspectivas multidimensionais, o desenvolvimento territorial também se tornou orientação para um processo que ultrapasse a lógica unidimensional e alcance fatores objetivos e subjetivos, que incidem sobre o desenvolvimento, servindo como base para políticas públicas no Brasil. Desse modo, o presente trabalho procura fazer uma análise das políticas de desenvolvimento territorial no Brasil do século XXI, e relacionar de que forma o marco referencial dessas políticas se alinham com a proposta de desenvolvimento como liberdade proposta por Sen. Observa-se que capacidades relacionadas à liberdade política, liberdade civil, preservação das identidades socioculturais e ambientais, entre outras, foram contempladas pela proposta política territorial, convergindo diferentes atributos teóricos do desenvolvimento multidimensional.

ABSTRACTTrack Quality Index (TQI) Value Prediction Based on Frequency Data and Traffic Load for 1067 Track Gauge: Track Quality Index (TQI) is an output from a measurement train. The higher TQI value indicates the higher level of railroad damage. The government has limitations to get the TQI value due to the limited number of measuring trains that are owned. Therefore, an alternative is needed to predict TQI values so that the safety aspect is guaranteed. To predict the TQI value on the width of the rail 1067 mm, a statistical regression analysis method was used. The variables used are TQI Parameters (Y) value, traffic frequency (X1) and traffic load (X2). Based on analysis, the form of the equations to predict the value of TQI parameters are YPert = 1,00.10-5 X1 + 1,47.10-7 X2 + 3,58; YAng = 2.08.10-5 X1 + 1.62.10-7 X2 + 3.77; YListr = 1,07.10-5 X1 + 1,60.10-7 X2 + 1,75; YLbspr = 1.76.10-5 X1 + 1.36.10-7 X2 + 0.32. The magnitude of the frequency and traffic load values in the TQI value categories are 10,230 train/yr and 11,524,169 tons/yr in categories 1, 17,050 train/yr and 19,206,948 tons/yr in category 2, 27,280 train /yr and 30,731,117 tons/yr in category 3 as well as more than 27,280 train/yr and 30,731,117 tons/yr in category 4.Keywords: track quality index; safety; regresion; equations.ABSTRAKTrack Quality Index (TQI) adalah output dari kereta ukur.

Authors: Kaczorowski Włodzimierz
Published: February 2021

In the period of Nobles’ Democracy, the art of war of the Polish-Lithuanian Commonwealth attained the highest level, making a real phenomenon in the then Europe. It owed its development, among others, to outstanding Hetmans of the Crown and Lithuania, victors in many battles, leaders surrounded by fame and admiration, genuine patriots. In the hall of fame of Grand Hetmans, Field Hetmans and Lithuanian Hetmans, a most prominent place is taken by Stanisław Żółkiewski (1747-1620).On 13 June 2019, Members of Parliament passed an occasional resolution dedicating the year 2020 to Stanisław Żółkiewski. The resolution reads, among others, “Stanisław Żółkiewski always put the good of Poland above his own benefits, stood faithfully on the side of successive kings, also in internal conflicts, despite the critical opinion of Sigismund III’s politics. He advocated religious tolerance and easing conflicts. […] The Seym of the Republic of Poland, upon acknowledging the great contributions of Stanisław Żółkiewski,creator of the victory of Klushino and a conqueror of Moscow, tenacious defender of the Mother Country for which he sacrificed his life, establishes the year 2020, which marks the occasion of the 400th anniversary of his death, the Year of Hetman Stanisław Żółkiewski.”

Analisar a percepção da equipe de enfermagem em relação à prestação de cuidado humanizado no centro cirúrgico. Trata-se de um estudo quanti-qualitativo. A amostra constitui-se de 34 profissionais da enfermagem. A coleta de dados foi realizada nos meses de março e abril de 2019, em um centro cirúrgico de uma instituição hospitalar privada. A análise de dados foi realizada por meio da técnica descritiva e por análise de conteúdo. O estudo respeitou a Resolução 466/2012 e foi aprovada junto ao Comitê de Ética (Protocolo nº 5). Participaram da pesquisa 34 profissionais da enfermagem, sendo 29 (85%) técnicos de enfermagem e 5 (15%) enfermeiros, com predominância de 100% do sexo feminino. É muito importante considerar que os participantes, do centro cirúrgico possuem uma concordância de opiniões para definição de cuidado humanizado, porém em se tratando das dificuldades apresentadas, utilizam-se das inconveniências diárias para justificar os empecilhos que colaboram para a não realização de um cuidado humanizado no setor. Para os profissionais de enfermagem, humanizar significa ter empatia, saber ouvir os pacientes, permitir-se entender e compreender o que está sendo vivenciado pelo paciente, e atendê-los com respeito e dedicação. Elucidando a importância das práticas de valores que facilitam o desenvolvimento da assistência.

From the mouth to gut: A microbial journey!
Authors: Apoorva S. R.
Published: February 2021

The oral microbiome invades almost the whole of the body, resulting in “n” number of systemic diseases. The gut is no exception in falling short to them. Many studies both in the four legged animals and their two legged successors (presumed to be the humans) have concluded that the oral microbiome can translocate to the gut and change its microbiota and eventually the immune defense. This ectopic displacement of oral microbiome specifically occurs in severe systemic diseases. Most commonly it is seen having its rage in patients with chronic periodontitis. Dysbiosis in the subgingival microbiota and immune defense, sometimes dysregulation in the gut, turns out to be the threat posed by the oral microbes. Among the other tiny troublemakers, Porphyromonas gingivalis remains the most serious. A dysbiotic gut microbiota may further cause diseases elsewhere in the body. The fact that chronic periodontitis may affect the gut microbiota suggests that the future would foresee a coordinated approach to the treatment of periodontitis and gastrointestinal diseases. Although this specific area of investigation is still a bud, it may portray different pathways for the oral microbiome to cause systemic diseases thence deserving a detailed probe furthermore.

The aim of the study is to find ways of specialty curriculum optimization on the basis of a multidisciplinary approach. The state of the art is characterized by the lack of well-defined criteria for the synergistic integration of disciplines within the specialty curriculum, which necessitated the solution of the following issues: in relation to which system-forming factor to compare disciplines; how to take into account the indirect contribution of a discipline to achieving the ultimate goal of the student’s development; how to measure the efficiency/weight of the discipline in the situation of selection. To deal with these issues, the following methods were used: theoretical analysis of literature; system (quantitative and qualitative) analysis of the National Qualifications Framework, Education Standards, specialty curricula and technical discipline work programs formats and content; activity analysis of the Education Quality Guarantors, curriculum developers and lecturers of disciplines on the basis of structured questionnaires. The obtained results were compared with the efficiency of students’ training based on the correlation and factor analysis. The study allowed determining the system-forming factor in relation to which the comparison of disciplines is performed in the situation of selection; finding a way of considering the discipline direct and indirect contribution to the development of students’ strategic competences; devising a formula for measuring the discipline weight in the context of the specialty curriculum. The study revealed a direct dependence of the discipline weight on the methods of its teaching and the synergistic effect of the student development from the interaction of disciplines selected on the basis of the proposed principles. The application of the obtained results will allow optimizing specialty curricula, which will improve the quality of the education and free up time for students’ self-development. The study of the multidisciplinary approach significance has proven its inexhaustibility as a source of new scientific research.

The paper proposes new circuit solutions for dual-fuel monar gas-steam plants (DMGSP), which provide an increase in the efficiency of electricity production in these plants by replacing the use of natural gas and increasing the share of generating "energy" steam by including an additional source of generation in the technological scheme steam - "preboiler", in which steam generation occurs as a result of the use of chemical energy of low-grade solid or liquid fuels - substitutes for natural gas of low or medium calorific value. DMGSPs are considered in two variants of operation of their utilization circuit: under conditions of heating and evaporation of feeding water, or only heating of this water. The results of calculations of the effectiveness of the implementation of these schemes on the basis of a monar gas turbine plant in comparison with the basic installation "VODOLEY" and a gas turbine plant of a simple scheme are presented.

On quantum tensor product codes
Authors: Fan Jihao , Li Yonghui , Hsieh Min-Hsiu , Chen Hanwu
Published: February 2021

We present a general framework for the construction of quantum tensor product codes (QTPC). In a classical tensor product code (TPC), its parity check matrix is constructed via the tensor product of parity check matrices of the two component codes. We show that by adding some constraints on the component codes, several classes of dual-containing TPCs can be obtained. By selecting different types of component codes, the proposed method enables the construction of a large family of QTPCs and they can provide a wide variety of quantum error control abilities. In particular, if one of the component codes is selected as a burst-error-correction code, then QTPCs have quantum multiple-burst-error-correction abilities, provided these bursts fall in distinct subblocks. Compared with concatenated quantum codes (CQC), the component code selections of QTPCs are much more flexible than those of CQCs since only one of the component codes of QTPCs needs to satisfy the dual-containing restriction. We show that it is possible to construct QTPCs with parameters better than other classes of quantum error-correction codes (QECC), e.g., CQCs and quantum BCH codes. Many QTPCs are obtained with parameters better than previously known quantum codes available in the literature. Several classes of QTPCs that can correct multiple quantum bursts of errors are constructed based on reversible cyclic codes and maximum-distance-separable (MDS) codes.
Efficient rate-adaptive reconciliation for CV-QKD protocol

Published: February 2021

Information reconciliation protocol has a significant effect on the secret key rate and maximal transmission distance of continuous-variable quantum key distribution (CVQKD) systems. We propose an efficient rate-adaptive reconciliation protocol suitable for practical CV-QKD systems with time-varying quantum channel. This protocol changes the code rate of multi-edge type low density parity check codes, by puncturing (increasing the code rate) and shortening (decreasing the code rate) techniques, to enlarge the correctable signal-to-noise ratios regime, thus improves the overall reconciliation efficiency comparing to the original fixed rate reconciliation protocol. We verify our rate-adaptive reconciliation protocol with three typical code rate, i.e., 0.1, 0.05 and 0.02, the reconciliation efficiency keep around 93.5%, 95.4% and 96.4% for different signal-to-noise ratios, which shows the potential of implementing high-performance CV-QKD systems using single code rate matrix.

In this work, we analyze the behavior of continuum single-photon, two-photon and coherent states in some quantum communication schemes. In particular, we consider the single-photon in a Mach-Zenhder interferometer, the Hong-Ou-Mandel interference, the quantum bit commitment protocol and a new protocol for secure transmission of sampled analog signals. Furthermore, it is shown an equation for estimating the spectral distribution of the single-photon produced by a heralded single-photon source using four-wave mixing in an optical fiber.
NMR for Mixture Analysis: Concentration Ordered Spectroscopy
Authors: Yuan Bin , Zhou Zhiming , Jiang Bin , Kamal Ghulam Mustafa , Zhang Xu , Li Conggang , Zhou Xin , Liu Maili
Published: February 2021

A novel approach, concentration ordered NMR spectroscopy (CORDY), is being proposed based on the principle that the ratio of NMR peak area to its associated number of spins is proportional to the concentration of the assigned compound.CORDY generates a pseudo 2-dimensional NMR spectrum with chemical shifts in one axis and concentrations in the other, resulting both in separation and quantitation of components in complex samples. The method was validated by applying on three samples. It was demonstrated that CORDY could successfully provide separation up to two orders of magnitude in concentration dimension, for the samples used in current study.

PERCEPTION OF COMMERCIAL AND SOCIAL ADVERTISING BY GENERATION Y IN THE CZECH REPUBLIC
Authors: Bulanda Ivana , Kadekova Zdenka , Kosiciarova Ingrida , Vavrecka Vladimir
Published: February 2021

Advertising as the dominant tool of marketing management and marketing communication has become an inextricable part of culture and society. Its influence significantly affects its immediate surroundings. The current period, characterized by a communication boom, allows for a more aggressive application of advertising in public contexts as well as in managerial solutions. Advertising thus penetrates all aspects of life and its setup can be found in both commercial and non-commercial spheres. Thanks to perception, advertising becomes an incentive that stimulates purchase of products, services, but also ideas. Perception reflects reality through the sense organs, and each instance of perception is complemented by subjective factors, a process linked to past experiences. The study presents partial results of research that examined perception of commercial and social advertising by the Generation Y customer segment in the Czech Republic. The research used the method of data collection by questionnaire with implementation of the semantic differential method with a seven-point rating scale to find out what denotative and connotative meanings Generation Y respondents attach to the terms commercial and social advertising. The research data were processed using descriptive and inferential statistics. The resulting findings are related to perception of the terms commercial and social advertising by the examined Generation Y group in their semantic space. The findings show that the concept of commercial advertising is perceived in predominantly negative connotations for the entire research group, and to absence of distinction on their part between the terms commercial and social advertising.
Patriarcado, feminismo y construcciones de género en la ficción especulativa The Handmaid´s Tale
Authors: García A. Erick , Fuenmayor C. Verónica
Published: February 2021

El presente artículo hace parte de la fase inicial de la investigación titulada El Cuerpo: uso y tratamiento en el seriado televisivo distópico, la cual busca dar cuenta de los planteamientos realizados en la serie televisiva “The Handmaid’s Tale” (Hulu, 2017) en relación con el feminismo, el sistema patriarcal y su visión con respecto a las construcciones de género. Asumimos dichos planteamientos como un cuestionamiento al sistema patriarcal y a la serie como uno de los ejemplos de ficción televisiva en los que puede evidenciarse la conexión entre el arte y la política, ya que, como plantea Ana María Pérez (2013), “las manifestaciones artísticas son políticas, porque suponen un desacuerdo, una confrontación con las particiones de la realidad sensible. El gran poder de subversión que poseen estas experiencias estéticas en general es su capacidad para ampliar los sujetos, los objetos y los espacios adecuados para

el debate, creando nuevos escenarios para la política” (p. 196). En el caso que nos ocupa, consideramos esta ficción como una manifestación artística que, además de brindar opciones de entretenimiento, realiza planteamientos que destacan importantes problemas de la cultura occidental y, gracias a su posibilidad de difusión masiva, es un espacio que posibilita la reflexión y el debate en torno a temas políticos de la actualidad.

Published: February 2021

Objective.Construct and evaluate the care cascade for pulmonary tuberculosis in the indigenous population of the department of Cauca (Colombia) and identify existing gaps.

Methods.Mixed-methods sequential explanatory design. In the first phase, the pulmonary tuberculosis care cascade for the indigenous population of Cauca was evaluated. Data were obtained from secondary sources and all cases diagnosed from 1 January 2016 to 31 December 2017 were included. In the second phase, semi-structured interviews were done with nine program coordinators and 11 nursing auxiliaries to explain identified gaps. Absolute and percentage values were estimated for each of the steps and gaps in the care cascade. Quantitative and qualitative results were triangulated.

Results.In 2016 and 2017, an estimated 202 patients with respiratory symptoms were expected to be positive and 106 cases of pulmonary tuberculosis were reported among the indigenous population of the department of Cauca. A gap of 47.5% was found for diagnosis, since only 52.5% of subjects were diagnosed in health services. This gap was explained by poor quality of samples and flawed smear techniques; flaws in correct identification of patients with respiratory symptoms; limited access to diagnostic methods, such as culture and molecular tests; and limited training and high turnover of personnel in health service provider institutions.

Conclusions.The tuberculosis control program should focus actions on bridging the gap in case detection in the indigenous population.
Sustainability in chronic disease prevention: lessons from the Salud al Paso program in Ecuador
Authors: Sacoto Fernando , Torres Irene , López-Cevallos Daniel F.
Published: February 2021

This study analyzes the conditions and possibilities of sustainability of the Salud al Paso program of the Metropolitan Health Secretariat of the Municipality of Quito, Ecuador, as an example for similar initiatives, in the context of the changes made by the new administration in May 2019. The analysis of the implementation of this initiative, focused on the prevention of noncommunicable diseases (NCDs), was based on the program’s user database, the information gathered on the perspectives of operational staff, knowledge of the program, and the opinion of local leaders and opinion leaders of the Quito Metropolitan District, as well as official information. Based on this data, the study identified factors that could have facilitated or hindered its sustainability and documented the rationale to suspend the on-demand activities included in the program and limit activities to the care of populations under municipal responsibility (day-care centers, schools and colleges, markets, elder care programs, and employees) and patients with identified cardiometabolic risk. The insufficient institutionalization of the program, conceived as a project with an insufficient vision of its sustainability in time, was mentioned as a possible obstacle by leaders and operational staff. The growing prevalence of NCDs requires initiatives for their prevention, which must be institutionalized to ensure their continuity and overcome eventual changes of government. In addition, future interventions similar to Salud al Paso should establish better sectoral coordination articulation, especially with the Ministry of Public Health and other service networks.

Authors: Elias Fadia , Rabah Hussein , Salih Mohammad , Boushnak Mohammad , Said Christina
Published: February 2021

Background: Breast cancer is the most common and costly disease in Lebanon, but data on cancer stage and mortality are scarce. Aims: This study aimed to assess the effect of mammography screening campaigns in reducing the breast cancer stage at diagnosis. Methods: A secondary analysis was conducted of data from the Ministry of Public Health’s Cancer Drug Scientific Committee database. The medical files of 3320 newly diagnosed breast cancer patients between 2012 and 2017 were reviewed. Demographic and pathology characteristics, cancer stage at diagnosis and presence of receptors were extracted and analysed. Results: The median age of the patients was 53 (interquartile range 36–72) years. Most patients had positive estrogen and progesterone receptors. Patients < 35 years mostly lived in South Lebanon, had advanced stages of cancer (III and IV) at diagnosis and were more likely to have triple negative breast cancer than the older groups (31.3% versus 16.7%). Advanced stage at diagnosis was common outside Beirut (60.4% in Bekaa and 54.7% in North Lebanon). In the period 2012–2017, the trend in early stages (I and II) at diagnosis decreased from 55.6% to 41.9%, while advanced stages (III and IV) increased from 44.4% to 57.9%. Conclusion: Efforts to downstage breast cancer through mammography screening in Lebanon have not succeeded. Implementation of genetic testing and tailored approaches for Lebanese women are recommended for future campaigns.

En este trabajo se presenta la implementación del modelo matemático bidimensional CCHE2D para caracterizar la hidrodinámica del río Paraná Inferior, en el tramo comprendido entre el km 410 y el km 452 de la ruta de navegación Santa Fe-Océano. La batimetría del cauce se definió a partir de relevamientos realizados por la Dirección Nacional de Vías Navegables-Distrito Paraná Inferior (DNVN-DPI) entre los años 2010 y 2012. Asimismo, para definir los límites del cauce se utilizaron imágenes satelitales y cartas náuticas del Servicio de Hidrografía Naval (SHN). Se realizaron simulaciones, en régimen permanente e no-permanente, utilizando respectivamente caudales aforados y caudales generados mediante transformación de niveles (zw) en caudales (Q), con la curva zw-Q del km 448. Los caudales simulados variaron entre 11640 m3/s y 28600 m3/s, a los cuales le corresponden tiempos de excedencia de 97.7 % y 0.3 % respectivamente. De esta manera, se representaron condiciones de aguas bajas, medias y altas del río. Los resultados del modelo hidrodinámico fueron contrastados con mediciones de caudales realizadas mediante ADCP (Acoustic Doppler Current Profiler) por FICH (2004-2006) y con niveles hidrométricos diarios registrados en Rosario (km 416) y en Puerto San Martín (km 448) por la Prefectura Naval Argentina (PNA). Los valores del coeficiente de rugosidad de Manning, obtenidos en el proceso de calibración del modelo, variaron entre 0.024 s/m1/3 y 0.025 s/m1/3, mientras que, la viscosidad turbulenta y las tensiones adicionales de Reynolds se estimaron a partir del modelo de dos ecuaciones k-e. Los resultados obtenidos indican que el modelo hidrodinámico simula satisfactoriamente la dinámica del flujo en el tramo estudiado, tanto en régimen permanente como no-permanente; ya sea en lo que concierne a la reproducción de niveles hidrométricos, pendientes hidráulicas, profundidades, distribución de velocidades y caudales específicos en secciones transversales; como así también, en lo que respecta a los caudales derivados en las bifurcaciones del cauce
