Показана возможность повышения (в десятки раз)аппаратурной надежности за счет исключения из состава ТРС мощных передатчиков и применения вместо них маломощных антенных приемопередающих модулей (АППМ),синфазноработающих в составе ФАР. Представлены преимуществами ТРС: возможность длительной работа без технического обслуживания, снижение вдвое энергопотребления, а также глубокая унификация построения ТРС разного класса на основе унифицированных АППМ.

New breakthrough technical solutions for tropospheric communication based on cognitive radio stations with a phased antenna array (PAA) are considered. These solutions provide the possibility of increasing the hardware reliability tenfold due to exclusion of powerful transmitters from tropospheric stations (TS) and using instead of them low-power antenna receive-transmitting modules (ARTM), operating in phase as part of the PAA. The advantages of such TSs are shown that enable long-term operation without maintenance, halving power consumption, as well as deep unification of the construction of TSs of different classes based on unified ARTMs.

Neuromarketing político-ideológico:
Authors: Martínez Daniel
Published: July 2021

El trabajo analiza el rol del neuromarketing aplicado dentro de la dimensión político-ideológico [NPI], como herramienta comunicacional para construir discursos hegemónicos: su influencia en la sociedad y su esfuerzo por invisibilizar elementos subordinantes; lo que le asigna un rol como arma para Operaciones Psicológicas [PsyOps], y una ventaja para las guerras híbridas informativas, dentro de las que se disputa el poder, local e internacionalmente. Para esto, se realiza una revisión bibliográfica para plantear las principales variables para el análisis del NPI, en la construcción y justificación de la lógica de dominio, y sus posibles usos, para elaborar narrativas contrahegemónicas.

Authors: Jácome Orozco Álvaro , Sierra Matamoros Fabio Alexander , Lozano Neira Laura Camila
Published: July 2021

Introducción: un mejor conocimiento de las mujeres lactantes, para el diseño de estrategias que fomenten la lactancia materna exclusiva, permitirá mejorar las tasas actuales. El uso de instrumentos de medición en conceptos como la actitud frente a la lactancia permiten este propósito. El objetivo del estudio fue desarrollar y validar una escala que mida la actitud frente a la lactancia. Métodos: se definieron 17 ítems tipo Likert. Se aplicó la escala a 518 madres con productos sanos, a término y en el posparto inmediato, en dos instituciones de Bogotá. Los resultados se evaluaron mediante la teoría clásica de prueba y teoría respuesta del ítem mediante un modelo de crédito parcial. Resultado: se encontró una validez semántica adecuada. El análisis factorial exploratorio y del contenido de los ítems definió un solo constructo: la actitud. Los índices de consistencia interna y confiabilidad fueron moderados. Los estadísticos de ajuste infit y outfit permitieron conservar todos los ítems en la escala. Las preguntas que más aportaron a la medición evaluaron el conocimiento sobre los beneficios de la lactancia y el uso de leches de fórmula. La escala posee ítems para medir los niveles bajos y medios de actitud, pero requiere otros para discriminar niveles altos. La función de información mostró que la escala es adecuada para medir los niveles medios y bajos de actitud. Conclusión: la escala desarrollada para la actitud hacia la lactancia materna es válida para discriminar el constructo en pacientes con niveles bajos y medios, lo que muestra su utilidad para identificar madres que se beneficiarían de apoyo en esta actividad. Palabras clave: actitud, lactancia materna, escalas.

Authors: Pardo Escallón Judith Consuelo , Pardo Beltrán Sonia Adriana
Published: July 2021

Introducción: el consumo de comida rápida conlleva un desequilibrio energético y, en especial, el exceso de aporte de grasas saturadas, lo cual se ha asociado con un aumento de la incidencia de enfermedades crónicas no transmisibles. El objetivo de esta investigación fue evaluar el aporte calórico y nutricional de los menús infantiles ofrecido en establecimientos de comida rápida de Bogotá. Método: se realizó un análisis cuantitativo de menús infantiles de establecimientos de comida rápida y se estimó el porcentaje de adecuación de calorías y nutrientes. Se tuvieron como referencia las guías alimentarias basadas en alimentos para mayores de 2 años para la población colombiana. Resultado: se evaluaron 6 establecimientos representativos a nivel nacional y sus 14 menús infantiles. Se encontró que el valor calórico y de grasa total de un establecimiento con sus 4 menús cumplen con el porcentaje de adecuación. En cuanto al porcentaje de adecuación en nutrientes, se encontró que el 36 % de los menús lo cumplen para proteína, el 50 % para grasa saturada y el 21 % para carbohidratos totales. En cuanto al azúcar adicionada y sal, se encontró que el 35 % y el 50 % de los menús infantiles, respectivamente, lo cumplen. Conclusión: algunos establecimientos de comida rápida ofrecen menús infantiles nutricionalmente balanceados de acuerdo con lo establecido por las guías alimentarias de Colombia. La comida rápida no necesariamente es sinónimo de comida no saludable. Es necesario promover la reformulación en aquellos menús no adecuados. Palabras clave: menú infantil, comida rápida, ingesta de calorías y nutrientes.
Terapia nutricional en el soporte vital extracorpóreo
Authors: Rebagliati Victoria
Published: July 2021

Los pacientes que requieren de soporte vital extracorpóreo se ubican entre los enfermos más críticos de la terapia intensiva. Actualmente se reconoce que la desnutrición proteica en los pacientes críticos puede prolongar los días en asistencia respiratoria mecánica (ARM) y la estadía en terapia intensiva, así como también aumentar la mortalidad y las complicaciones a largo plazo. Sin embargo, como la oxigenación extracorpórea es una técnica relativamente nueva, la evidencia en nutrición es muy escasa, por lo que surgen miedos al momento de alimentar artificialmente a estos pacientes. La presente revisión bibliográfica pretende responder los interrogantes sobre el abordaje nutricional adecuado basado en evidencia científica y la propia experiencia de un centro de referencia cardiovascular. La terapia nutricional debe llevarse a cabo en forma interdisciplinaria entre nutricionista, médico y enfermero con el fin de garantizar la colaboración de todos para alcanzar las metas nutricionales y, de este modo, prevenir la desnutrición. Palabras clave: terapia médica nutricional, asistencia circulatoria mecánica, oxigenación extracorpórea, desnutrición.
Fútbol argentino y ciencia
Authors:   , Fusetti Pablo
Published: July 2021

Dentro del ámbito futbolístico argentino, la experiencia es una palabra que se nos aparece con recurrencia cuando hablamos sobre los fundamentos que se exponen para estar al frente de un equipo, dirigir un club, aprender a jugar o simplemente tomar la palabra en el fútbol. Quien la vivió desde adentro pareciera ser quien efectivamente tiene la credencial para acceder al ámbito de la enseñanza o de la gestión deportiva; se da por sentado que quien tiene mucha experiencia en contacto con la pelota —ya sea en el potrero o en el club— es quien sabe jugar al fútbol. Estas cuestiones nos llevaron a preguntarnos sobre las profundidades de dicho concepto, su uso y tratamiento tanto en el plano científico y filosófico como en el educativo y futbolero. ¿A qué se refieren cuando mencionan experiencia? ¿Es lo mismo hablar de experiencia que de vivencia? ¿La experiencia es la que brinda conocimiento? ¿Quien tiene experiencia como jugador puede estar a cargo de un equipo o a cargo de un club? ¿Quién jugó tiene la credencial para enseñar? ¿Hay un conocimiento del cuerpo que se puede transmitir? ¿La experiencia es individual? ¿Es la experiencia con el ambiente la que nos brinda conocimiento? ¿La experiencia se da en el potrero o en el club? Para todos estos interrogantes aproximaremos una serie de respuestas.

Published: July 2021

Malaria masih merupakan masalah kesehatan di Indonesia. Ketidaksesuaian hasil
pemeriksaan laboratorium merupakan salah satu masalah diagnosis yang sering dijumpai dalam praktik klinis. Pemeriksaan mikroskopis apusan darah pasien merupakan standar diagnosis malaria. Hasil pemeriksaan tersebut dapat memberikan informasi lebih lanjut mengenai spesies dan kepadatan parasit yang secara umum berkorelasi dengan kondisi klinis pasien. Manifestasi klinis penderita malaria bervariasi, bergantung pada beberapa faktor, seperti endemisitas daerah dan sistem imunitas tubuh penderita. Kepadatan parasit dan keterampilan pemeriksa sangat berpengaruh dalam mendeteksi parasit pada sampel darah penderita malaria tanpa gejala. Kami melaporkan kasus seorang pria Indonesia berusia 45 tahun yang dirujuk ke Rumah Sakit Haji Adam Malik, Medan pada tahun 2019, dengan demam intermiten, anemia dan beberapa keluhan lainnya. Pemeriksaan mikroskopis pada apusan darah secara serial tidak ditemukan adanya parasit. Namun pada pemeriksaan mikroskopis pada sediaan biopsi sumsum tulang menemukan benda yang diduga sebagai “plasmodium”. Pasien dinyatakan menderita penyakit malaria berdasarkan hasil biopsi sumsum tulang dan kondisi klinis pasien serta mendapatkan obat antimalaria. Namun kondisi klinis pasien tidak mengalami perubahan yang signifikan. Tatalaksana penyakit lain juga diberikan berdasarkan diagnosis penyakit penyerta lainnya dan menunjukkan perbaikan, walaupun lambat. Perbedaan hasil pemeriksaan laboratorium dan kondisi klinis pasien bisa saja terjadi dalam praktik klinis. Keputusan klinis suatu penyakit sebaiknya dibuat berdasarkan standar diagnosis penyakit tersebut.

(p = 0,133, R = 0,198). Hasil tidak bermakna dalam penelitian ini dapat disebabkan karena tidak diketahui data baseline jumlah trombosit dan riwayat pengobatan pasien malaria sebelumnya.
A SECOND CHANCE FOR ENTREPRENEURS IN THE REPUBLIC OF MOLDOVA: CHALLENGES AND SOLUTIONS
Authors: Alexandra NOVAC , Elena ACULAI , Lidia MAIER
Published: July 2021

The relevance of offering a second chance is determined not only by the need to mitigate the consequences of business failure and motivate the entrepreneur to continue his entrepreneurial activity, but also by the impact on the country’s economy, as business closure leads to job losses, a worsening of the financial possibilities of the national and local budgets, reduction of competition and other negative trends in the internal market. The importance of these issues has increased significantly in the context of the COVID-19 pandemic, leading to significant deterioration of the Moldovan business environment.
The aim of the paper is to identify the barriers and needs of entrepreneurs, who face financial or other difficulties, are in a state of insolvency, have gone through restructuring/bankruptcy proceedings and would like to benefit from a second chance in Moldova. The research methodology is based on the analysis of legislative acts in the field; statistical data analysis; the results of 16 semi-structured interviews with entrepreneurs on elucidating the factors that favor and hinder the entrepreneurial activity, related to obtaining a second chance in business. The interviews were conducted between April and August 2018.
The research results showed that both internal factors (insufficient financial resources, knowledge of crisis management, mismanagement, insufficient staff qualification, including the entrepreneurial skills / experience of the owners, the lack of people with certain professions) and external (related to insolvency legislation, limited information on the possibilities that can be used in case of failure) are determining for taking a second chance.
PRIVATE CONSUMPTION IN THE EUROPEAN UNION: A COMPARATIVE STUDY
Authors: Nicoleta ONOFREI , Adina Teodora PAŞA,
Published: July 2021

The aim of this paper is to study consumption of households from an economic and cultural perspective in the European Union with 28 Member States during the period 2010-2019. For this purpose, we compared the Eastern European countries, dominated by rapid economic growth and development with the Western European countries, which represent the most developed countries in the EU-28. From this perspective, we proposed a multidimensional analysis of consumption that includes macroeconomic indicators of households’ wealth, which strongly influence their consumption together with an overview on expenditure by consumption purpose. Moreover, we have also considered Hofstede’s cultural dimension theory based initially on four cultural dimensions (power distance, individualism versus collectivism, masculinity versus femininity, and uncertainty avoidance) to observe the impact national culture plays on households’ consumption in Eastern and Western European countries tracking the historical changes of these countries. Our methodological approach consisted in descriptive and inferential statistics based on the selected economic and cultural indicators. Pearson’s product-moment correlations were calculated to assess the correlations between the variables. Our analysis shows that the level of wealth is lower in Eastern European countries compared to Western Europe, which influences significantly the private consumption in these countries. Moreover, the systematic differences of national culture between Eastern and Western Europe influence strongly the private consumption of their population. Results of this paper indicate that in Eastern European countries the highest share of expenditure is allocated to primary needs such as food, non-alcoholic beverages, alcoholic beverages and cigarettes to the detriment of health, education, recreation and culture.
YOUTH ATTITUDES TOWARDS GENDER ROLES WITHIN FAMILY
Authors: Olga GAGAUZ , Anna CHIVACIUC
Published: July 2021

Young people are leaders of change in any society; therefore, studying their attitude towards gender roles in the family is of particular interest in predicting changes in their behaviour and identifying the policy measures needed to achieve sustainable progress in gender equality.
The study aimed to research the attitude of youth towards gender roles in the family to determine the influence of the levels of education, gender and other characteristics on gender preferences in relations – traditional or egalitarian. It is based on data from a sociological survey of youth in Chisinau, conducted in 2019 on a representative sample (N = 506).
The theoretical basis of the study was the multiple equilibrium theory (Esping-Andersen et al., 2013). The study results showed that the perception of young people regarding the essential qualities of men and women is still under the pressure of stereotypes and corresponds to the intermediate balance model characteristic of the transition from traditional roles based on the division of labour to modern egalitarian ones. This circumstance implies an equal division of responsibilities and family roles between women and men. On the one hand, youth tend to an egalitarian type of marriage and family relationships, and on the other, they adhere to traditional views of family roles. Although there are some differences in attitudes towards gender roles within the family between natives of Chisinau and young people from other localities, they are still not so pronounced. Youth with higher education are more likely to prefer an egalitarian distribution of gender roles than youth with a lower level of education. Girls more often than boys strive for gender equality in the family. However, in some aspects, such as the responsibility of men for the family’s financial support, the importance of the material situation of a partner, they more often express traditional views.
Fast Mutual Authentication Using RSA Moduli
Authors: Anisimov Anatoly , Novokshonov Andrey
Published: July 2021

We describe a fast three-round mutual authentication protocol for parties A and B belonging to the same coalition group. Parties A and B keep their own independent long-term private keys that are used in the process of authentication and can be used for other purposes. The scheme assumes an initial setup with a trusted third party T. This party initiates another secret information that includes factors of a large RSA modulus. For authentication, both parties must demonstrate each other the knowledge of their private keys without revealing them and the ability to factorize a large RSA modulus. Thus, the protocol based on the suggested scheme provides reciprocal authentication. The scheme possesses all desirable properties of an interactive proof, i.e., completeness, soundness, and zero-knowledge. The security of the protocol relies on assumptions of difficulty of the RSA factorization and existence of a cryptographic hash function.

Authors: Le Van-Duc , Cuong Bui-Tien , Cha Sang-Kyun
Published: July 2021

This paper applies a Spatiotemporal Graph Convolutional Recurrent Neural Network which is a tight combination of a Graph Neural Network (GNN) to a Recurrent Neural Network (RNN) architecture for air pollution forecasting in long-term for the entire city. Our model can effectively learn the spatial and temporal features of the air pollution data and its influential factors (e.g. weather, traffic, external areas) at the time. Our method achieves better performance than a state-of-the-art ConvLSTM model in air pollution forecasting and a hybrid GNN-based model that separates GNN and RNN in discrete layers.

Pulpitis is one of the most prevalence complication of dental caries. In the structure of visits for dental care, the diagnosis of pulpitis accounts for 14 – 20%. Preservation of the vitality of the pulp is very important for the tooth and for the body as a whole. Since the death of the neurovascular bundle leads to a abnormalities of the protective, trophic and plastic functions of the tooth, causing the loss of its functional signifcance, the development of complications and, as a consequence, removal of a tooth. So, conservative methods of pulpitis treatment must be used to prevent the spread of inﬂammation in the dental pulp. The success of both direct and indirect biological methods for treating pulpitis in more than 50% of cases depends on the drugs and materials used for the pulp. In the arsenal of dentists there are appropriate new generation drugs with a suffciently high evidential base, however, the problem of fnding the "ideal" material is still crucial.

Published: July 2021

The outcome of endodontic treatment directly depends on the high-quality instrumental and medical treatment of root canals. The most effective, widespread and well-known antiseptic used for rinsing root canals is sodium hypochlorite. Unfortunately, in the process of irrigation complications arise in the form of sodium hypochlorite of various concentrations extrusion into the periapical region. We must not forget about the anatomical and topographic features of the structure of nearby structures, such as the mandibular canal and the maxillary sinus. The aim of the clinical case is to assess the depth of irrigant penetration into the periodontal area using radiography and to develop an algorithm for actions in the event of a hypochlorite accident.

Today, dentists face a diffcult task: in conditions of unfavorable environmental conditions, increased stress, high allergization of the body, tolerance of microorganisms to antibiotic therapy, to fnd a treatment method that will stop the inﬂammatory process, accompanied by an abundance of opportunistic microﬂora, improve the quality of life of the patient and reduce the cost of treatment of patients with diseases of the oral mucosa.

Aim. of the study:to conduct a comparative analysis of the effectiveness of the treatment of the method of ozone therapy and the drug "Kolegel" relative to the generally accepted methods of treatment of patients with aphthous stomatitis.

Materials and methods.The patients were divided into 3 groups according to the method of treatment: conventional, with the use of ozonated peach oil and the application of the drug "Kolegel". The results were evaluated on the 3rd, 7th, and 14th days using computer planimetry and pain syndrome assessment using the visual analog pain scale (VAS: VAS).

Results.For 1-14 days, the drug "Kolegel" and applications with ozonated oil proved their effectiveness, for 7 days, patients did not complain of pain, there was a reduction in the area of aft, which indicated the relief of the inﬂammatory process.

Conclusions.According to the results of the study, it was proved that the inclusion of the drug "Kolegel" and ozone therapy in the treatment regimen of patients with aphthous stomatitis is a highly effective method and contributes to the acceleration of reparative regeneration.

Authors: Soyfer Eli M , Fleischman Angela G
Published: July 2021

Myeloid malignancies, stemming from a somatically mutated hematopoietic clone, can cause a wide variety of clinical consequences, including pancytopenia in myelodysplastic syndrome, overproduction of three myeloid lineages in myeloproliferative neoplasm, and the rapid growth of immature hematopoietic cells in acute myeloid leukemia (AML). It is becoming clear that inflammation is a hallmark feature of clonal myeloid conditions, ranging from clonal hematopoiesis of indeterminate potential to AML. Fundamental findings from laboratory research on inflammation in myeloid malignancies has potential implications for diagnosis, prognostication, and treatment in these diseases. In this review, we highlighted some pertinent basic science findings regarding the role of inflammation in myeloid malignancies and speculated how these findings could impact the clinical care of patients.

Chitin - the structural component of fungal cell wall, arthropodal exoskeleton, microfilarial sheat and egg of helminths. Allergens of this organisms cause allergic diseases. The potential role of chitin in allergic reactions has been discussed. Other studies have suggested that chitin preparations may skew immunity away from T-helper-2-mediated allergic responses. Chitinases, enzymes that can degrade chitin polymer, and chitinase-like proteins might also play an important role in allergic disease pathogenesis.
