This article proposes a network traffic monitoring system with filtering elements at the data link layer (L2) of the OSI model. This article presents the general requirements and approaches to the construction of the proposed monitoring and filtering system. The developed device is built on the basis of SDN technology, which makes it possible to create a more flexible and multifunctional network device compared to traditional network devices. In the process of developing the device, standard methods and components available to the masses were used. Under the conditions of the tasks set, a schematic diagram of the developed device based on the TE0714 TRM model board and the SFP standard transceiver is presented. It is proposed to use the device for a monitoring system with filtering elements. Network traffic monitoring is proposed to be implemented based on the SNMP protocol to collect information from critical network nodes. It is proposed to implement network traffic filtering based on a "white" list of MAC addresses to limit the list of devices that have access to the system. The practical significance of this article lies in the description of the approach to the development of a fundamental device for monitoring public and personal networks with flexibly defined additional and basic functions. The proposed device, thanks to the use of SDN technology, provides individual customization for customer requests, which means the possibility of expanding functionality without purchasing new hardware and firmware.

This paper presents the results of preparing a virtual bench for modeling and detecting network attacks using a freely distributed intrusion detection system (IDS). The relevance of the work is related to the growing demand for IDS as sources of information security events for security information and event management (SIEM) systems. A comparative analysis of the most popular freely distributed open-source network IDSs was carried out and the choice of the Zeek system for its use in the project was substantiated. The work uses Zeek network logs, which contain important and structured information about the analyzed network traffic. The laboratory bench was built on the basis of a Linux virtual machine and a Mininet network simulator. A graphical representation of the developed virtual stand is proposed. An experimental study of the effectiveness of an intrusion detection system is demonstrated by simulating a network denial of service attack and further analyzing the received network traffic using IDS tools.

El humanitarismo va a la guerra. Tensiones entre violencias, derechos humanos y humanismo militar en la posguerra fría
Authors: Piedrahita-Ramírez Luis Felipe , Restrepo-Arboleda Sara María
Published: June 2022

Este artículo reconstruye y problematiza el debate sobre la relación entre humanitarismo y uso de la fuerza. Para ello analiza los giros históricos en la familia humanitaria y la  consolidación del nuevo humanitarismo político. A continuación, se revisa la convergencia entre las agendas  del nuevo humanitarismo y el proyecto de un orden  internacional liberal intervencionista en cuyo núcleo se sitúa un discurso transformador, maximalista y utópico de los derechos humanos. Luego, se recogen algunas perspectivas críticas de ese humanismo militar de la posguerra fría, prestando especial atención a los estudios críticos del humanitarismo y a los análisis pospositivistas de la política internacional. Finalmente, se presentan algunos argumentos en favor de quienes consideran que el humanitarismo debe recuperar el mayor grado de neutralidad e independencia posible, alejándose del intervencionismo militar y de los proyectos de transformación a gran escala del sistema internacional. El texto plantea una revisión crítica de la literatura  especializada sobre el humanitarismo contemporáneo, cuya naturaleza es esencialmente interdisciplinar, combinando los  fundamentos teóricos y metodológicos provenientes de la antropología, el derecho, la filosofía, las relaciones internacionales, y las reflexiones provenientes de los trabajadores humanitarios sobre el terreno.
Giro ético del normativismo humanitario: el derecho a ser llorado
Authors: Ruiz Gutiérrez Adriana María
Published: June 2022

Nuestra deflación espiritual ante la muerte de los otros debido a nuestro deseo intenso por negar la propia muerte constituye, más que un obstáculo insalvable, una oportunidad ética y política para pensar y construir otros discursos y prácticas normativas frente a la destructividad de la que somos capaces y a la que estamos expuestos de manera irremediable. Sin duda, las normas de aprehensión y de reconocimiento de lo humano dependen, ante todo, de nuestras disposiciones afectivas ante la muerte de los otros, cuyas pérdidas juzgamos, diferencialmente, como meritorias o indignas de ser lloradas, según el valor o el desvalor que adjudicamos a sus vidas. De ahí la  importancia del derecho a ser llorado como condición ética y política para la humanización de todos. Este artículo, basado en Esquilo, Sigmund Freud y Judith Butler, cuenta con tres apartados: (1) la cuestión de la destructividad humana; (2) vidas matables, inmerecedoras de duelo; (3) el poder afectivo del duelo.
“Rerum vel dictu obscenarum” De subventione pauperum y las ambivalencias de las narrativas humanitarias de la modernidad temprana
Authors: Restrepo Luis Fernando
Published: June 2022

En este ensayo se examina el tratado De subventione pauperum (El socorro de los pobres, 1526) del humanistaJuan Luis Vives como una narrativa humanitaria de la modernidad temprana. De forma contradictoria, el plan para auxiliar a la población indigente presenta una visión despectiva de la pobreza que refleja las contradicciones del proyecto civilizador del humanismo cristiano renacentista y revela las biopolíticas del naciente Estado moderno y la razón imperial humanitaria. En el primer apartado se analiza el tratado como una narrativa humanitaria, prestando atención al papel de las emociones en la interpelación al lector, especialmente la ambivalente presencia del discurso del asco -un aspecto poco explorado en el humanitarismo-. En el segundo apartado se examina el plan para regular la caridad pública y controlar a la población indigente en relación con las nuevas formas de gobernabilidad de la modernidad temprana, en diálogo con los aportes de Foucault en cuanto al surgimiento de lo que en la época se entendía por “la policía”, una serie de tecnologías del poder para regular la vida y el trabajo de la población en conjunto. El estudio se centra en las contradicciones internas de las narrativas humanitarias a partir del análisis del texto de Vives.
Humanitarismo cliché: miradas migrantes hacia la retórica de la piedad peligrosa en We Need New Names y Americanah

Published: June 2022

El sujeto migrante, por su condición intermedia de traductor cultural, presenta una perspectiva ambiguasobre los clichés del humanitarismo. El origen de las protagonistas de We Need New Names y Americanah les permite relatar la experiencia vivida con la ayuda humanitaria, a la vez que la migración y la distancia de esta condición, adquiriendo una voz crítica e irónicamente denunciatoria sobre las paradojas de la piedad. No obstante, en el mismo movimiento, su asentamiento en el país de recepción las desorienta y les hace perder  progresivamente su reflexión mordaz, convirtiéndolas en consumidoras del sufrimiento a la distancia y reforzando la colonialidad del poder. Primero, veremos el desarraigo de  los sujetos migrantes, Ifemelu y Darling; luego, la evolución de las políticas y paradojas de la piedad y su influencia en el espectáculo del sufrimiento desde la mirada del sujeto  migrante; finalmente, el artificio del humanitarismo cliché de los medios de comunicación, de la fotografía y su relación con las ong.
¿Pero leer novelas nos hace mejores? Ficción literaria y desarrollo moral
Authors: Altuna Belén
Published: June 2022

La novela ha sido consagrada como una de las “técnicas de experiencia vicaria” fundamentales, que adiestran nuestra habilidad para ponernos en la piel de otras personas. No han sido pocos los que han visto un claro efecto moral en esa permanente exploración de la alteridad. El artículo repasa los argumentos (1) de los entusiastas de esa idea, los que creen que leer novelas nos hace más empáticos y solidarios; (2) de los moderados, quienes consideran que ayuda ante todo a ejercitar nuestro juicio moral, y (3) de los escépticos, que apenas encuentran ningún fin moral en ese hábito. Revisa a continuación algunas complejidades del desarrollo moral, que hacen improbable una fácil conexión, y termina distinguiendo los modos en que la lectura de novelas sí puede contribuir a cultivar la humanidad que hay en nosotros y a ahondar en el humanitarismo.
Teaching Writing Courses by Blending Online and Traditional Classroom Instruction for Underachieving Language Learners
Authors: AGGUN Nazli
Published: June 2022

Some studies (Grgurović, 2011; Banados, 2006; Chenoweth et al., 2006) have showed that blended instruction would enhance language learning. Similarly, some researchers (Picciano, 2009; Goertler, 2012; Neumeier, 2005) have defined blended instruction and recommended that educators try the best blend for their classes. Motivated by the findings of the relevant literature on blended instruction, the current study aims to find whether blended learning would make a difference in the writing scores of students compared to traditional face-to-face education and to establish the students’ perspective on the usage of technology at writing courses with quantitative and qualitative research methods. For the purpose of the study, one experimental and control groups were chosen from the School of Foreign Languages, Gaziantep University. The 13 students in the experimental groups are taught writing with blended learning, while 13 students are taught writing with traditional face-to-face education for one month. The students in both groups have the same schedule, age, English level, and classroom facilities. The results of the analysis done by SPSS show that the experimental group's writing scores are higher than the control group's writing scores. To learn the students’ perspectives in the experimental group, semi-structured interviews have been done after the experience. The results show that the students are not satisfied with the usage of current technology at writing courses. On the other hand, they reported they were satisfied with blended learning. The students also gave some suggestions about the implications of technology in and outside of the classes.

Published: June 2022

Camptothecin (CPT) has attracted much attention due to its potent antitumor activities. However, the undesirable physicochemical properties, including poor water-solubility, unstable lactone ring and severe adverse effects limit its further application. In this study, two water-soluble prodrugs, CPT-lysine (CPTK) and CPT-arginine (CPTR), were designed and synthesized by conjugating lysine or arginine with CPT, improving its solubility, pharmacokinetic properties and tumor penetration. Importantly, the introduction of arginine into CPTR contributed to the mitochondria-specific delivery, which increased mitochondrial reactive oxygen species (ROS) generation, induced mitochondria dysfunction and enhanced cell apoptosis and in vivo anti-cancer effect. This strategy is believed to hold great potential for organelle-specific synergistic anti-tumor therapy.

Published: June 2022

This research investigates presentation anxiety among undergraduate Malaysian Chinese students in a private university where English language is used as a medium of instruction in private universities in Malaysia. There is little research on the difficulties in the teaching and learning such as presentation anxiety among ESL (English as a Second Language) Malaysian Chinese students. The objectives of this study are to explore the different levels of presentation anxiety and to identify coping strategies used by the students with English-speaking anxiety among undergraduate Malaysian Chinese students in a private university. Hence, a mixed method approach is used which involves a questionnaire and semi-structured interview. Sixty participants responded to the English Language Classroom Anxiety Scale (ELCAS) questionnaire and six interviewees who took part in the questionnaire were purposively chosen to conduct the interview. ELCAS Quantitative results indicated that ESL Malaysian Chinese students in the private university showed moderate levels of presentation anxiety when doing presentations. As for the qualitative data, the findings revealed that students often rehearse and practice before their presentation to cope with the existing anxiety. We suggest that language instructors are to deliver a more positive learning environment and to provide adequate guidance in class to improve the presentation skills and speaking skills among ESL Malaysian Chinese students as well as other ESL and EFL (English as Foreign Language) students.

Between Conflict and Solidarity: Pandemic Media Coverage of Romanian Intra-EU Labour Migrants
Authors: Vincze Hanna Orsolya , Balaban Delia Cristina
Published: June 2022

The Covid-19 pandemic affected Romanian intra-EU labour migrants in a particular way and challenged the established themes associated with and the social roles assigned to them in news discourses. During the first wave of the pandemic, Covid-19 hotspots were reported abroad in Romanian migrant communities, the most notorious example being at the Tönnies factory in Germany. The pandemic brought to prominence the precarious working conditions of labour migrants employed in agriculture and especially in the food industry. Wider discussions, conflicts, and solidarity actions were generated around this topic. In the present study, we identify the main themes and topics present in the Romanian media coverage of Romanian labour migrants, as well as the way foreign, particularly German, media perspectives were integrated into and domesticated in the Romanian coverage. Findings show that both the Romanian and German media used, to a certain extent, the media coverage of this exceptional pandemic situation to invite reflection on the general social costs of migration and on the responsibility of political actors in the migrants’ country of origin, in their country of destination, and at the level of EU institutions. However, the perspective of the migrants was underrepresented in the media coverage.
Migrants as “Objects of Care”: Immigration Coverage in Russian Media During the Covid-19 Pandemic
Authors: Bodrunova Svetlana S. , Smoliarova Anna
Published: June 2022

For over 20 years, Russia has been within the top five most attractive countries for immigrants. Before the pandemic, the federal policies that stimulated the immigration of cheap workforce contradicted the public perception and the media coverage of immigrants as problematic communities. Unlike labor immigrants, the EU refugees from the Middle East were depicted as a challenge for the disunited and unhospitable EU, and re-settlers from Donbass were portrayed highly sympathetically. These differences remain virtually unstudied. We explore the coverage of immigrants and refugees in Russia during the Covid-19 pandemic to see whether, under its impact, the coverage was equal and humanistic rather than different and politically induced. Based on content analysis of 12 Russian federal and regional textual media and four TV channels in 2020, we show that the differences described above have persisted and even intensified during the pandemic, supported by pro-state media, with only marginal counterbalancing from oppositional news outlets. The discourse about labor immigrants pragmatically focused on immigration-related problems for businesses and the state, channeling the authorities’ position on immigrants as “objects of proper care,” while the EU refugees were depicted as “objects of improper treatment.” In both discourses, immigrants were equally deprived of their subjectivity. In general, the immigration-related issues were not a major focus, especially for regional media, and the pandemic has not led to the re-humanization of immigration coverage.
Thermoelectric model of a heterojunction bipolar transistor taking into account the voltage drop on the current-carrying metallization
Authors:   Kotelnikov Institute of Radioengineering and Electronics of RAS, Ulyanovsk Branch, Sergeev Vyacheslav A. , Hodakov Alexander M. ,   Kotelnikov Institute of Radioengineering and Electronics of RAS, Ulyanovsk Branch
Published: June 2022

A 3D thermoelectric model has been developed to calculate the temperature field in the comb structure of a heterojunction bipolar transistor formed on the surface of a rectangular semiconductor crystal with the length of the emitter metallization paths comparable to the size of the crystal, taking into account the inhomogeneous distribution of current density under the emitter paths due to voltage drop on the resistance of current-carrying metallization. The model is based on the solution of the thermal conductivity equation together with a system of equations for the distribution of the potential for metallization of the emitter track and the current density under the track in the COMSOL Multiphysics software environment. It is shown that as a result of the combined effect of the voltage drop on the resistances of the emitter tracks, the inhomogeneity of the temperature field in a crystal with limited dimensions and the strong dependence of the emitter current density on temperature, the temperature and current density distributions along the emitter tracks change character: from monotonously and weakly decreasing from the beginning of the track to the end in the isothermal approximation, these distributions become non-monotonic and significantly heterogeneous. At the same time, the maximum current density and temperature with an increase in the operating current shifts from the beginning to the center of the tracks. It has also been found that with the crystal sizes unchanged, an increase in the length of the tracks leads to a certain decrease in the coefficient of inhomogeneity of the temperature distribution.
Application of the Interpolation Method of Sequential Computation of the Fourier Spectrum to Sparse Images

Published: June 2022

Interpolation Method of Sequential Computation of the Fourier Spectrum (IMSCS) is used for the reconstruction of sparse digital images. Peculiarities of application of the method are investigated on different types of images with a large sparseness (from 90 to 99 percent of information is missing). To improve the work of IMSCS, when considering the large sparseness of the initial data, its totality includes a procedure for additional iterative refinement of each of the restored harmonics of the spatial spectrum. As an alternative approach, to determine the analysis by objective criteria, spline interpolation is chosen. The conducted study allows us to conclude that it is fundamentally possible to use IMSCS to restore rarefied images, both for the reconstruction of gaps, and in order to reduce the amount of data.

Mediante el estudio de sus pronósticos literarios, que siguen la moda propuesta por Torres Villarroel, impresos entre 1742 y 1769, se pretende reconstruir su perfil autorial y analizar las estrategias editoriales empleadas para posicionarse en el mercado almanaquero del momento. Todos estos impresos se entienden como un único proyecto editorial planificado con un fin concreto y definido. Se analizan, además de los artificios literarios, los paratextos de sus obras para elaborar las redes de sociabilidad literaria: la portada, las dedicatorias, las censuras y las poesías paratextuales.

Transgénesis en animales de granja
Authors: Marqués Margarita M. , Baro Marta F. , Nicolás Silvia , Bayón Yolanda
Published: June 2022

La transgénesis en animales de granja ha experimentado una importante evolución desde sus inicios en la década de los años 80. La eficiencia de las técnicas ha aumentado considerablemente y, a las primeras experiencias llevadas a cabo mediante microinyección pronuclear en el cigoto, le han seguido otras metodologías como la transferencia nuclear de células somáticas, que ha tenido particular importancia en estas especies domésticas. Además, en los últimos años, se han desarrollado herramientas de edición del genoma que permiten una alta especificidad en la modificación genética. Entre las numerosas aplicaciones de los animales transgénicos, se encuentra la producción de proteínas de uso terapéutico humano. También, cabe destacar las investigaciones con objeto de generar animales modificados genéticamente para ser utilizados como modelos de enfermedades humanas, o bien destinados a proporcionar órganos para xenotrasplante. Además, en el ámbito estricto de la Producción Animal se está explorando la utilización de la transgénesis para incrementar la resistencia de los animales a enfermedades o mejorar la cantidad y calidad de sus productos.
Drogas marinas: los animales marinos como fuentes de compuestos antitumorales
Authors: Laborda Navia Antonio José , Martín San Sebastián Manuel
Published: June 2022

La evolución ha dotado a muchos organismos marinos con un arsenal de productos químicos que emplean para fines defensivos o sociales. Gracias a esto, las formas de vida marinas constituyen una fuente importante de compuestos bioactivos, implicados hoy en el descubrimiento de nuevas drogas para tratar diversas enfermedades. Miles de esos compuestos han sido ya descubiertos y están siendo evaluados en diversos ensayos biológicos, muchos de ellos en el campo de la oncología. En él, los avances en la determinación de la estructura molecular, síntesis, etc., han permitido que algunos de ellos como citarabina, halaven y yondelis, entre otros, hayan pasado ya a formar parte del mercado farmacéutico. Sin embargo, aún existen limitaciones para explotar todo el potencial de estos compuestos y, en la actualidad, la investigación está dirigida al descubrimiento de nuevas rutas del metabolismo secundario y de novedosas formas de producción sostenible. Además, resulta prioritario el conocimiento de la biodiversidad marina y su conservación, para proteger moléculas de posible interés en el futuro.
Papel de los receptores NMDA de glutamato en la vulnerabilidad neuronal después de isquemia cerebral transitoria en rata
Authors: Vilaboa Severiano dos Anjos
Published: June 2022

Cuando no llega la sangre a una parte o todo el cerebro (ictus) se produce una disminución de oxígeno y nutrientes (especialmente glucosa) que lleva a la muerte de muchas células de las regiones afectadas. Un área particularmente vulnerable a la isquemia es el hipocampo, una región implicada en los mecanismos de memoria y reconocimiento de lugares. En este proyecto de tesis se pretende averiguar si esta diferencia en la vulnerabilidad celular en el hipocampo es debida a uno de los mecanismos de señalización celular del sistema glutamatérgico
Una evaluación ambiental previa de la Universidad de León. Ecoauditoría ULE
Authors: Felipe Lucia María
Published: June 2022

El proyecto de Ecoauditoría ULE ha sido realizado en el Campus de Vegazana de la Universidad de León durante el período 2003-2007 por alumnos de 5º de Ciencias Ambientales. Gracias a él se han puesto de manifiesto aspectos muy relevantes en cuanto a la sostenibilidad general del campus. Concretamente, la baja conciencia de ahorro energético en sus instalaciones, la gran variabilidad de consumo eléctrico y agua en los diferentes centros, la preferencia de caminar como medio de transporte para los miembros universitarios, seguida de un uso masivo del turismo con un solo ocupante, y finalmente, la percepción global positiva del aspecto ambiental del campus, exceptuando ciertas necesidades, como mejorar la iluminación nocturna y las plazas de aparcamiento para bicicletas
“Guías” virtuales. ¿Hacia una nueva generación de “guías” de naturaleza?
Authors: Ordóñez Antonio , Pérez Hidalgo Nicolás
Published: June 2022

Con el fin de aumentar esta fiabilidad se trabaja en el Proyecto

Biodiversidad Virtual (www.biodiversidadvirtual.com), proyecto que

pretende acercar a los ciudadanos al mundo de la biodiversidad. Para ello se

utilizan las fotografías digitales que los naturalistas realizan en sus salidas de

campo almacenándolas y ordenándolas en una plataforma virtual de Internet con

tres objetivos básicos: la explotación científica de los datos al estar estos

georreferenciados, la divulgación y docencia usando las carpetas taxonómicas

donde se están ordenando las fotografías y finalmente servir de apoyo a

organizaciones conservacionistas, para hacerlas partícipes, a través de sus

fotografías, del conocimiento “in situ” de la biodiversidad en áreas concretas

Ainda temos limites? Uma análise dos desafíos enfrentados pelas mulheres no mercado de trabalho no Rio Grande do Sul-Brasil
Authors: Correa Silveira Josianne , Freddo Fleck Carolina , Pacheco Abbondanza Márcia V.
Published: June 2022

Quando as mulheres se dedicam à qualificação profissional e a alcançar postos de trabalho melhores, podem surgir barreiras sutis e invisíveis, denominadas na literatura como “teto de vidro”. Sendo assim, esta pesquisa teve o objetivo de identificar as principais barreiras associadas ao crescimento profissional da mulher na atualidade, tendo como base as seis barreiras apresentadas por Russel, Rush e Herd na pesquisa de 1988. O estudo é descritivo-exploratório, com abordagem quantitativa, em que se aplicou um questionário estruturado, tendo como respondentes 163 mulheres atuantes no mercado de trabalho, de todas as regiões do estado do Rio Grande do Sul. As barreiras identificadas como mais ativas na atualidade são as que compreendem as características inadequadas ao gerenciamento, assim como as questões familiares, sociais e educação ou experiência limitadas.
Towards a descontruction of symbolic violence in a sample of advertising discourse. A critical discourse perspective
Authors: Martínez Lirola María
Published: June 2022

This article examines the representation of women in the advertisements used by Dolce & Gabbana, in order to observe the examples of symbolic violence associated with women. The main objectives of this study are: 1) to deconstruct the main visual strategies used by Dolce & Gabbana to represent women in its newsletter; and 2) to characterize the main types of symbolic violence in the texts analysed. Data were collected from the newsletter used by Dolce & Gabbana to advertise their products through the internet from January to December 2016–19. The data are analysed based on the critical discourse analysis model of social actors proposed by van Leeuwen (2008) and Kress & van Leeuwen’s (2006) models of visual grammar.
Mujeres en física: identidad profesional y persistencia de la anomalía
Authors: Estradé Sònia
Published: June 2022

En este articulo se abordan las dificultades de las mujeres jóvenes para verse haciendo física, así como las diferencias en la identidad profesional de hombres y mujeres en física, y las violencias simbólicas que nos atraviesan a las mujeres en este campo. Esto nos lleva a interrogarnos sobre la cultura profesional en la que nos desempeñamos, y sobre cómo nos afecta trabajar en un campo tan masculinizado donde, en consecuencia, es más difícil colaborar con otras mujeres. Partiendo de estos análisis valoramos en clave género los cambios que se están dando en los últimos años, en los que la física en España se está volviendo cada vez más neoliberal.
