Career, Covid-19, and Care: (Gendered) Impacts of the Pandemic on the Work of Communication Scholars
Authors: Müller Kathrin Friederike , Peil Corinna , Weder Franzisca
Published: February 2023

The study at hand analyzes the impact of the Covid-19 pandemic and related restrictions on scholars in the area of media and communication studies. It aims to highlight inequalities in the negative effects of the pandemic on academic output by examining the working conditions of scholars, taking into account gender, parenthood, and the partnership-based division of professional and care work. The quantitative survey was directed at communication scholars in Germany, Austria, and Switzerland. The findings show that there are no significant gender differences in terms of changes in academic output during the first 15 months of the pandemic; instead, disadvantages were observed in terms of parenting, regardless of the gender of the parents. Gender-specific effects could be detected concerning family situations and partnerships. Here, male participants are more often found in relationships in which the partner only works half-time, than women who mostly live with a partner who works full-time. The data suggest that gender differences related to changes in the time allotted for professional and care work and academic output are leveled out by the characteristics of the academic career model in which German-speaking scholars work. Nevertheless, gendered structures in academia and partnerships shape how the impact of the pandemic on professional work is experienced.
Representing Life and Death in Care Institutions: Between Invisible Victims and Suffering Old Women
Authors: Adlung Shari , Backes Annabella
Published: February 2023

The article examines the representation and (in)visibility of ageing people in German care institutions during the Covid-19 pandemic. Within the framework of a qualitative content-analytical and discourse-analytical study of 185 articles, including 108 images from German newspapers, the authors trace the patterns behind the representation of ageing people. In so doing, they argue that in the media discourse ageing people are often represented without agency and in a strongly homogenised way as “others.” By emphasising pre-existing conditions and vulnerability, older and disabled people appear naturally at risk. The article also problematises the mere counting of life and death in care institutions, which contributes to a naturalisation and symbolic annihilation of the death of ageing people. Furthermore, the authors identify the notion of the suffering old woman as a key figure in pandemic media discourse, performing a critical function. She embodies an appeal to society to show sympathy and solidarity and to act reasonably with respect to the pandemic measures yet contains no elements of discursive agency or personal characteristics beyond that. Additionally, the suffering old woman reinforces traditional patterns of patriarchal representation. The authors conclude that the pandemic has placed the German care crisis in settings of institutionalised geriatric care into the media spotlight. However, the comprehensive inclusion of ageing people has been absent. Emphasising one’s own ability and thus adapting to the midlife years seems to be the only way to precarious inclusion for ageing people in the discourse.

Published: February 2023

This article aims to identify different terms and concepts regarding tall buildings and evaluate the presence and hierarchy these buildings have on a global level. The methodology used considered the global database of tall buildings published by the Council on Tall Buildings and Urban Habitat. Six essential regions of the world were analyzed and classified as clusters. Forty-eight buildings were quantitatively described. As a result, thirteen terms and eighteen different concepts were found. The spatial configurations in terms of height and year of construction of each building, defined the population trends in the cities that make up each cluster. This research confirms a significant diversity of criteria for naming buildings in height. Tall buildings occupied by offices predominate in the clusters evaluated. Residential usage is not the most common occupation.
Import Processing and Trade Costs
Authors: Carballo Jerónimo , Graziano Alejandro , Schaur Georg , Volpe Martincus Christian
Published: February 2023

We estimate import processing costs based on the time it takes to import. Our theory extends existing time-cost measures to account for uncertainty in import processing. We use detailed, highly disaggregated data on import processing dates and import values to provide evidence for our theory and estimate processing costs consistent with the theory. The evidence shows that our extensions to time-cost estimates are economically relevant to determine processing costs. We estimate that the tariff equivalent import processing costs is as high as 18 percent. WTO estimates suggest that the full implementation of the 2013 Trade Facilitation Agreement would reduce the time to trade by 1.5 days. In that case, processing costs would decrease to 13 percent.

using LoRa Technology
Authors: Promput Sommart , Maithomklang Somkiat , Panya-isara Chawalit
Published: February 2023

Water quality is one of the most important variables impacting human life. Generally, water quality measurements must be conducted on-site. If the region to be investigated is large, several test locations will be required. Repeated evaluations of water quality will be complicated and time-consuming. Therefore, a real-time water quality monitoring system is required to protect and monitor the water in order to take proactive measures for contamination. This project focuses on the aforementioned concerns and uses LoRa technology and the Node-RED application to develop environmental sensors that monitor and display water quality. It is the measurement and collection of data on water quality parameters, including temperature, electric conductivity, pH, air quality, and turbidity, according to the region requiring analysis. The microcontroller processes the sensor data before transmitting it via the wireless network to the database, where it is displayed on the Node-RED dashboard. The experimental results demonstrated that a range of 2.0 km can be used to transmit information in areas where LoRa technology encounters obstacles. Furthermore, the IoT-based monitoring system is able to monitor water quality in real time and display a Node-RED dashboard. It was determined that usability assessments were more efficient and convenient.
Study of the Behavior and the Mechanical Properties of Adhesively Bonded Polymer Matrix Composites Under Mechanical Loading
Authors: Spasova Daniela , Argirov Yaroslav , Petrov Plamen , Mechkarova Tatyana
Published: February 2023

Glass fiber reinforced Polymer matrix composites (PMCs) have a complex set of properties - high specific strength and hardness, good corrosion and chemical resistance, and most of all low relative weight, making them the preferred material over metallic materials in a number of industries (aircraft, boat building, renewable energy facilities and many others). The main aim set in the present work was reduced to the obtaining of PMCs made by adhesive bonding of two composites with a matrix of different types of resin (vinyl ester and epoxy) and the study of their behaviour in determining their mechanical properties. The studies were carried out with four types of adhesively bonded PMCs made in the form of laminates produced from a combination of three types of resin (two types of vinyl ester and one type of epoxy resin) and reinforced with biaxial fiberglass. The aim is to combine the lack of shrinkage of the epoxy resin with the better mechanical properties and better productivity of the vinyl ester resin. An analysis to determine shear strength, tensile strength and bending strength of the investigated composites was made. A macrostructural fractographic analysis to investigate the material behaviour under mechanical loads was carried out.

Published: February 2023

The system of intrusion detection dataset enables machine learning to recognize attack activity in the network. The intrusion, however, is naturally imbalanced, most of the traffic is normal traffic. Moreover, a certain attack is more popular than others. Therefore, the number of cases is highly imbalanced with the majority of attacks dominated by Distributed Denial of Services (DDoS), Denial of Service Hulk (DoS_Hulk), and PortScan more than 4.5% of attacks data. While the minority attack such as DoS_goldeneye, DoS_slowloris, DoS_slowhttptest, Web Attacks, Infiltration, Bot, and Heartbleed was only recorded in less than 1% of attack data. We propose data generative model (DGM) using the Conditional Generative Adversarial Network (CGAN) to improve the class of minorities of the IDS dataset. In this study, we tested the performance of the Data Generative Model based on CGAN in the CICIDS2017 dataset. There are new attacks in this dataset, including Bot, Web_attacks, Infiltration and Heartbleed. According to our experiments, the model successfully detect new attacks and improves the weighted f1-score by 99,92% compared to that of achievers by existing methods using the CICIDS2017 dataset.

Authors: Prasetyo Adi Budi , Wahyudi Rizki , Tahyudin Imam , Kusuma Selvia Ferdiana , Oktaviana Luzi Dwi , Barkah Azhari Shouni , Artono Budi
Published: February 2023

Edge detection of an image is needed to obtain information related to the size and shape of an image. There are numerous methods for detecting edges, including the Prewitt, Laplace, and Kirsch operators. Each edge detection method has different performance and results. Therefore, this study aims to analyze the performance comparison of the Prewitt, Laplace, and Kirsch operators. The analysis process is carried out using MSE, PSNR and Image Contrast values. Based on the experiments that have been carried out, the best edge detection is produced by the Prewitt operator. The average MSE and PSNR values obtained were 4.63 and 41.79 dB. The Laplace operator is good in the contrast value of 17.77. However, the contrast value only serves as a supporting parameter to clarify the differences in the results of each edge detection operator. So it can be concluded that the Prewitt edge detection method is the best method among the other two methods.
A Mathematical Model for Rationality in Timetable Planning
Authors: Kostadinova Iva , Totev Vasil , Ivanov Ivan
Published: February 2023

The preparation of a study timetable (or schedule) depends on the school or university for which it is made and on the specific work practices applied in this educational institution. The preparation of a school timetable in a school or university aims to plan for the conduct of classes in certain academic disciplines for a certain period of time, while optimally engaging the classrooms and professors available for the relevant period.
The aim of this paper is to provide a mathematical model for rationality in planning a study timetable. This mean to make forecast on whether the accepted number of students, organised in groups, could be instructed during defined period of time in the available classrooms in the educational institution. The developed model aims to make better use of available classrooms and places for students in them. Calculating a rationality ratio will give the educational institution an idea of the:

 Need for more classrooms;
 Need to extend the study period (number of days for the planned semester)
 Need for more optimal planning of the study timetable and better use to the rooms.

The prepared model also includes a coefficient of specific rationality, in case the educational institution has classrooms of different capacities - for lectures and practical exercises.
The developed mathematical model can be useful to higher education institutions for the purpose of planning their educational activity and it can be applied before the actual process of planning a study schedule.
The data used and calculations results serve as the basis for an in-depth analysis related to the requirements for the educational process and the opportunities provided by the educational institution.

Misseling as a modern tool of unfair sales of banking products and services in commercial banks
Authors:   Taganrog Institute of Management and Economics, Sinichenko Olesya A.
Published: February 2023

Introduction. Misseling has become a problem for commercial bank customers today. Misseling can be found both in large credit institutions and small banks. Formally, this is not a violation of the law, but, in fact, misleading of the client. In fact, there is a bank fraud when selling a banking product or service. Despite the fact that this phenomenon can be found in almost any bank to varying degrees of participation, from a scientific point of view it has not yet been sufficiently studied, although recently the Bank of Russia has made an attempt to regulate this process legislatively. Theoretical analysis. The article analyzes the concept of “misseling” and its place in the technique of unfair sales of banking products and services in commercial banks. Modern types of misseling are distinguished: unfair information, related sales, opaque pricing, sale of unsuitable products, product substitution. Empirical analysis. It was revealed that the number of misseling cases in the banking sector in the analyzed period increased, one of the reasons was a significant reduction in the key rate after its high value, low level of the population’s financial literacy. Against the background of a significant decrease in complaints related to investment life insurance, there was an increase in complaints related to cumulative life insurance, as well as the number of all other complaints on various topics. Results. The directions of improvement on encountering misselling by the Bank of Russia, commercial banks and clients are formulated and described. One of these areas was the introduction of new rules for the sale of financial products by the Bank of Russia. If the Central Bank of the Russian Federation detects a violation on the part of a commercial bank, it has the right to issue an order to the financial institution to suspend the sale of the product until the problems are eliminated. In some cases, the Bank of Russia may oblige the bank to buy back from customers all products sold in violation and make a full refund.
Using Multi-state Markov models to predict the probability of borrowers’ default
Authors:   Saratov State University, Balash Vladimir A. , Balash Olga S. ,   Saratov State University, Faizliev Aleksey R. ,   Saratov State University
Published: February 2023

Introduction. After the crises, lenders realized the importance of assessing the risk of default on loan portfolios in various economic conditions. Modeling of credit risk assessment occurs mainly using internal ratings of banks based on probabilistic models of defaults of borrowers over a certain period of time. Theoretical models. Three models are considered. The first is a naive Markov model with R states. The transition matrix is given. The second is a Markov model with multiple states with covariates. Macroeconomic indicators are proposed as covariates. The third model is multinomial logit regression. Approbation of Markov models and multinomial regression on simulated and real data of borrowers’ defaults. We investigate the possibility of using multi-state Markov models to predict borrower defaults in financial institutions over time. Three approaches are considered for credit risk modeling. The first approach assumes that the transition probability matrix is constant over time, and the residuals of the Markov model and logistic regression are taken into account further when forecasting over the time horizon. The second one is supplemented by the Markov model, which takes into account the impact of default risks on migration, both individual factors of borrowers and the economic situation in the country. Using covariates, the models made it possible to simultaneously estimate the transition rate and the probability of erroneous classification of states. A multinomial logistic regression model is considered to compare the results obtained using multi-state Markov models. The proposed models are tested both on real and simulated data. Conclusion. The presented models show good predictive results with high accuracy of default estimates. The models reproduce the structure of the generated data quite well. The peculiarity of the multinomial regression model in predicting defaults is its adjustability, and Markov models estimate the probabilities of defaults. To implement the model, software R was used.
The legal nature of judicial reconciliation
Authors:   Saratov State University, Saratov State Law Academy, Duraev Taulan A. , Tyumeneva Natalia V. ,   Saratov State University
Published: February 2023

Introduction. The article examines the legal nature of judicial reconciliation with the participation of a judicial conciliator (hereinafter referred to as judicial reconciliation), and highlights the debatable nature of the topic under consideration. The authors state that it is necessary to disclose the legal nature of judicial reconciliation in order to clarify its place in the legal system of Russia and to identify functional links with other related institutions of substantive and procedural law. Problem statement. The article argues that the success of the introduction of the institution of judicial reconciliation into legal practice depends on the disclosure of its legal nature in the system of human rights tools and mechanisms. At the same time, the ambiguity of the term of “legal nature” itself contributes to uncertainty in this matter. It is proved that the content of the term of “legal nature” includes various signs of the phenomenon, which must be consistently disclosed in the process of cognition. The authors emphasize that the legal nature of judicial reconciliation is complex, dualistic. This is expressed in a combination of judicial (jurisdictional) and extra-judicial (non-jurisdictional, alternative) characteristics, which is clearly revealed in the dualism of the legal status of the judicial conciliator. Theoretical and empirical analysis. The analysis of the legislation shows that, on the one hand, a judicial conciliator is a former judge who has extensive practical experience in legal proceedings and a vision of the prospects for resolving the case; on the other hand, the judicial conciliator, while remaining part of the judicial system, is free from rigid conservativecorporatist judicial discipline when conducting judicial reconciliation and can, without excessive formalism and substantive resolution of the case, offer the parties mutually beneficial reconciliation conditions, under which the legal conflict will be resolved. Results. The authors conclude that the duality of the legal nature of judicial reconciliation is due to the convergence processes that take place in the Russian law and trends associated with the change in the configuration of the judiciary.

RESUMEN

La Bioética laica es en principio, una ética aplicada que permite afrontar los problemas generados por la tensión existente entre la ciencia y el ser humano. La actual pandemia causada por un agente infeccioso no conocido ha puesto de relieve la necesidad de la aplicación de esta ética aplicada, no ubicada en los laureles de lo etéreo o puramente intelectual sino más bien asentada en la realidad del día a día. La toma de decisiones desde todos los ámbitos del quehacer sanitario requiere este marco referencial fundamental; aplicación de correctos preceptos en las decisiones epidemiológicas, sanitarias y medidas políticas no puede ni debe hacerse sin este marco referencial; otrora el resultado será catastrófico.

Introducción La obesidad afecta al 22.1% de la población ecuatoriana y su prevalencia continúa en aumento. La cirugía bariátrica constituye una opción efectiva para su tratamiento pero alcanza apenas al 1% de la población afectada. Objetivo Describir la experiencia en la implementación del programa de cirugía bariátrica en el Hospital de Especialidades de las Fuerzas Armadas N°1. Materiales y métodos Estudio observacional, retrospectivo, desde febrero del 2016 hasta febrero del 2019; se incluyó características demográficas, seguimiento prequirúrgico, evolución del peso antes y después del procedimiento a corto, mediano y largo plazo. Resultados Se incluyeron 39 individuos, 74.36% fueron mujeres y el 25.64% hombres. La edad media fue 45.97 años (DS ±9.91 años); el índice de masa corporal medio en la primera valoración fue 41.04 kg/m2 (DS ±5.08), al primer mes se logró un porcentaje de reducción del exceso de peso del 21,75 % (DS ±14,66), al tercer mes del 42,84 % (DS ±18,27) y al año del 66,28 % (DS ±12,60), sin embargo, 13 pacientes abandonaron el seguimiento. Conclusión A pesar de la dificultad técnica y operativa para implementar un programa de cirugía bariátrica, queda demostrado su beneficio. Además, se debe enfatizar en que el seguimiento representa un pilar fundamental para el éxito de la cirugía a largo plazo.
A expansão urbana sobre manguezais e a geração de conflitos, riscos e vulnerabilidades em Marapanim e Maracanã: Uma revisão da legislação

Quando o crescimento urbano não é planejado, as dinâmicas de ocupação podem provocar sérias transformações no território. Este cenário torna-se ainda mais complexo quando o lócus abrange biomas vitais para a biodiversidade. É o que ocorre nos municípios de Maracanã e Marapanim, onde parte da população passou a ocupar áreas de manguezais. O artigo visa apresentar a sequência histórica de criação da legislação relacionada à ocupação irregular de manguezais. Para isso, foi necessário realizar um levantamento bibliográfico-documental acerca das leis, planos e políticas que permeiam a temática. A esta discussão, foram incorporados quatro conceitos norteadores: conflitos socioambientais, risco, vulnerabilidade e território. Como resultado, verificou-se que o Brasil ainda não despertou completamente para a urgência da implementação de medidas de prevenção de riscos e vulnerabilidade, sobretudo ao considerar seu extenso litoral, o qual nos últimos anos passou a ser habitado pela maioria da população. Embora a legislação brasileira conte com bastante densidade, sua aplicabilidade ainda necessita de reforços quanto às formas de lidar com os problemas locais.

O estudo faz uma revisão dos fundamentos normativos da política pública de mobilidade urbana e da governança interfederativa sustentável do transporte coletivo metropolitano. Busca-se responder como implementar a sustentabilidade no transporte coletivo metropolitano através da governança interfederativa? Assim, através do método de análise qualitativa, interdisciplinar e crítica, aplicação da técnica de análise documental e bibliográfica, com a revisão da legislação e amparada em documentos oficiais norteadores da política pública mobilidade urbana, transporte público e governança interfederativa, objetiva-se a definição dos elementos caracterizadores na compreensão da complexidade do tema. Parte-se dos documentos internacionais, constitucionais e infraconstitucionais como fundamentos que estruturam, a governança interfederativa sustentável do transporte coletivo metropolitano, considerando-se a pluralidade de setores econômicos, sociais e políticos, na busca de ambiente urbano metropolitano sustentável. Em derradeiro traça-se um caminho normativo para a construção de possíveis alternativas para implementar no solo urbano metropolitano uma política sustentável de mobilidade urbana a partir da governança interfederativa do transporte coletivo.

As mudanças do uso do solo em um território nem sempre ocorrem de maneira a garantir a sustentabilidade das atividades econômicas, visto que, a longo prazo, podem resultar em graves problemas ambientais. Este trabalho teve como objetivo analisar as mudanças de uso do solo no município de São Domingos do Araguaia, no sudeste do estado do Pará, com o intuito de apontar possibilidades de recuperação e/ou reabilitação dessas áreas buscando conferir maior resiliência aos agroecossistemas locais. Para a elaboração dos mapas de uso do solo, utilizou-se a base cartográfica e mapa de zoneamento econômico-ecológico do sudeste do estado do Pará. A elaboração dos mapas temáticos foi realizada junto ao Laboratório de Análise Ambiental e Representação Cartográfica, do Núcleo de Meio Ambiente da Universidade Federal do Pará. Foram elaborados mapas de uso do solo e observação de vegetação do município em uma série temporal de 2004 a 2014. Verificou-se que as áreas de pastagens arbustivas e pastagens herbáceas têm predominância no município, com consequente diminuição da área de vegetação primária. Recomenda-se a recuperação e/ou reabilitação das áreas degradadas, com a recomposição das áreas de proteção permanente e a integração de fragmentos florestais. Para isso, os gestores municipais devem instituir uma política local que estimule agricultores e pecuaristas a investir em sistemas produtivos mais resilientes como os sistemas agroflorestais.

A água é usada de modo diverso pelas sociedades para atender necessidades biológicas, econômicas, sociais, políticas, culturais, etc. A água pode ser significada como um serviço ambiental, por se tratar de componente fundamental na reprodução da vida humana, e do seu caráter social (coletivo), e também na reprodução biológica dos ecossistemas. Este artigo objetiva identificar os usos da água e analisar os significados da água para na Bacia Hidrográfica do Rio Itá, em Santa Izabel do Pará-PA. Para isso, parte de um recorte: a comunidade quilombola Boa Vista do Itá. Esse recorte apresenta dois objetivos específicos: identificar as relações de territorialidades (socioespaciais) e tradicionalidade (culturais) envolvendo a água. Como procedimentos metodológicos foram realizadas pesquisas bibliográficas e documentais, trabalhos de campo no qual foram realizadas entrevistas semiestruturadas e levantamento de registros fotográficos, posteriormente, análise dos dados obtidos.
