Todos estamos afectados por la pandemia. Por las consecuencias directas del virus solo algunos pocos aún, por estos lares. Impactados por una gran imagen de ficción, por un lado, y por una realidad material inimaginable, por otro. Oscilamos entre estas dos realidades. La enfermedad, que es como un viento veloz, invisible, silencioso y con destinos desconcertantes, provoca a la vez otros efectos, secundarios a las medidas que tienden a limitar la rapidez de la trasmisión viral, que implica limitaciones a la vida social, laboral, económica y personal: nuestros afectos, el aislamiento y la incertidumbre económica. El incremento de la pobreza va a ser una de las más graves consecuencias, especialmente en América Latina, por sus grandes diferencias sociales; la enorme informalidad laboral, con lo que implica en falta de seguro social y de salud para todos. También las consecuencias de percibir lo que nos muestra sucesiva e iterativamente la televisión y los medios en internet, de cómo este microorganismo, diminuto e incompleto para reproducirse, ha azotado en otros lugares lejanos, y no tanto, ciudades multitudinarias y poderosas. ¡Ni la riqueza lo detiene!

Aislamiento y circum:

Afectados, como todos, por los impactos subjetivos precipitados por el aislamiento, los psicoanalistas hemos apelado a nuestro arsenal conceptual para intentar hacerlos más comprensibles. Se ha hablado, en ese sentido, de «situación traumática compartida», se ha intentado trazar sus semejanzas y sus diferencias con las neurosis traumáticas y las neurosis de guerra descriptas por Freud, se han mencionado insistentemente las pérdidas y el consecuente trabajo de duelo que nuestra actualidad exige…
Mi impresión es que las categorías de trauma y de pérdida, en tanto articuladas al deseo inconsciente, tienen para el psicoanálisis un sentido altamente singular: es —por otro lado— lo que los torna operativos en nuestra clínica. Es lo que hace difícil «generalizar» la condición traumática de un acontecimiento disruptivo, por impactante que resulte desde una perspectiva convencional, y es también lo que hace problemático imputar a-priori un estatuto de «pérdida-a-duelar» a —por ejemplo— la muerte de alguien que nos es próximo, o la cancelación de un proyecto. Es la temporalidad del a-posteriori la que permite verificar, en el caso por caso, la significación de trauma o de pérdida: apresurarse a otorgarla, o darla por descontado, supone teñir con los propios prejuicios el acceso a la subjetividad de nuestros analizantes.

Differenciation of the Demographic and Socioeconomic Development of Districts in Czechoslovak Socialist Republic
Authors: Andrle Alois
Published: March 2022

In the first introductory part of the contribution the main attention is paid to the importance and changes of territorial differences during the post-war period. The initial major differences (inherited from the capitalist period and existing especially between the western and eastern parts of Czechoslovakia) have already been satisfactorily solved. However new differences are gradually arising. New territorial differences have indeed a different character - they are no more essential and relate mostly to small regions only. In the second part the author illustrates the contemporary territorial differentiation in the district scale on the example of the development and the present situation of population and its economic activity.
A Model of Spatial Relationships Between the Production and the Consumption of Agricultural Products in Czechoslovakia
Authors: Götz Antonín
Published: March 2022

The paper shows the self-sufficiency of regions and districts in Czechoslovakia in the agricultural production. In Czechoslovakia the consumption and the production of agricultural products were nearly brought into balance in 1984. The last map shows a cartographic model connecting districts of insufficient production with those of a surplus production.
The Impact of the Social Sciences and Humanities in Europe and Beyond
Authors: AZCÁRATE Asunción LÓPEZ-VARELA
Published: March 2022

Abstract: What is the role of the Social Sciences and Humanities (known collectively as SSH) in the journey to the Fourth Industrial Revolution? What is the impact of these disciplines for the challenges the world faces, supposedly defined by a highly dynamic phase of industrial
and social restructuring, where the adaptive capacity of societies needs to be enhanced by specific skills and techno-social dependencies? What is the role of SSH in building cognitive competences, and new professional paths? This paper, part of the special focus of the Annual Review of New
Directions in the Humanities, seeks to unveil the importance of SSH disciplines to the major STEM disciplines (science, technology, engineering, and mathematics). Although disciplines and research in Social Sciences and Humanities play a fundamental role in the production of knowledge relevant
to society, the last decade of the 20th century has seen a continuous trend towards their devaluation. After a relatively glorious period during the first half of the century, when SSH disciplines still held a relative social influence, the arrival of digital technologies in 1990s, accelerated
their decline. This article traces a brief overview of this decline and explores some of the causes as well as the challenges in valuing SSH. Focusing mainly on Europe, the paper presents the attempts, on behalf of the European Commission, to correct this decline. It also outlines some new
ideas that could help a true integration and transfer of knowledge across STEM AND STEAM disciplines, such as the creation of specific 'missions'. Precisely, one of the diagnoses of the Horizon 2020 experience in Europe has been that investment in research is not effectively linked to the
solution of specific problems. Thus, it is necessary to put in motion co-creation mechanisms among research disciplines and advance in the establishment of intersectoral bridges, bringing SSH research closer to the industry and other social sectors in order to solve the pressing challenges
we face (climate change, mass migration, economic crisis, etc.)

Social Criticism and Ethical Aspects in Patricia Esteban Erlés and Abert Soloviev’s Hypermedial Short Stories
Authors: CALVO REVILLA Ana
Published: March 2022

Abstract: In online communication, writers incorporate into fictional representation imaginaries that arise from the interaction between various artistic manifestations (text, photography and illustration). This paper explores the work of two spanish authors, Patricia Esteban
Erlés and Albert Soloviev in order to study the social impact and ethical aspects of hypermedial short stories in the virtual space, since their works function as vehicles for social criticism. At the same time, the paper addresses fundamental questions associated with the understanding
and interpretation of hybrid narrative microtexts.

Published: March 2022

Abstract: The purpose of this study is to analyze the current characteristics of organizational culture and climate in Kazakhstani higher educational institutions during the COVID-19 crisis. Materials for the study were collected from interviews and online discussions published
on the website of Al-Farabi Kazakh National University (KazNU). In addition, results from the social monitoring systems of the university’s educational activities as well as an official survey have been used. The study offers details of how Kazakhstani universities dealt with the crisis
by presenting KazNU case study. The paper presents the responsible actions developed at the university as well as the problems faced by students and teachers. One important lesson to be learnt is that educational organization needs to be more comprehensive, caring for appropriate technical
equipment, helping develop skills for staff and students, and include vulnerable groups of the population.
Energy Sensitivity Analysis by Lightning for a Transmission of Commercial Vehicles
Authors: Han S. G. , Park D. H. , Jeong J. K. , Song C. K.
Published: March 2022

Dynamic performance of transmission has a substantial effect on dynamic performance and fuel efficiency of vehicles, and is directly related to mass inertia moment of the transmission rotor. Rotors of light mass require a small amount of kinetic energy from vehicles that repeat acceleration and deceleration, which increases fuel efficiency as a result. In this study, equivalent inertia moments at different speeds were calculated by simplifying the transmission system, and, by using the kinetic energy equation related to rotational motion and translational motion of vehicles, required kinetic energy of each speed was calculated. Also, the probability of using different speeds to achieve a target distance was applied as weight in order to calculate the amount of kinetic energy required to achieve the target distance. Assuming that the rotor inside the transmission maintains its function while the mass was minimized, in this study, the relative effect of lightning the rotor was compared to the effect of lightning the sprung mass with regards to kinetic energy.
An Approach to Optimal Filtering of Time-Variant Systems via Finite Measurements
Authors: Zhao Snunyi , Shmaliy Yuriy
Published: March 2022

Fast optimal estimates are often required in control and signal processing. In this paper, we discuss an approach to optimal finite impulse response (OFIR) filtering for discrete time-variant systems using finite measurements. The mean square error is minimized to obtain the batch OFIR algorithm which requires measurements on an a finite horizon of N points. Fast iterative algorithm is found using recursions. It is shown that each recursion has a predictor/corrector Kalman filter (KF)-like format with special initial conditions. In this sense, the KF is considered as a special case of the proposed iterative OFIR filtering algorithm when N approaches infinity for known initial conditions. It has been confirmed by simulation that the iterative form of the OFIR filter operates much faster than the batch form.

Authors: Pak Jung Min , Ahn Choon Ki , Lim Myo Taeg , Shmaliy Yuriy S.
Published: March 2022

In this paper, we propose a new nonlinear f ltering algorithm that can provide more accurate and reliable localization compared with the pure particle f ltering (PF). In the proposed algorithm, failures of the PF are detected, and the failed PF is recovered using a f nite impulse response (FIR) f lter. The resulting f lter is called the combined particle/FIR f lter (CPFF). We demonstrate the performance of the CPFF by the indoor human localization.

Technological evolutions at Intelligent Transport Systems (ITS) is allowing that ubiquitous society use the ITS facilities to conducting their activities. At this scenario the paper presents a study case in order to use ITS technologies applied to conduct his activities, mainly for bus tracking. The study case presented in this paper uses the concept of IoT (Internet of Things) to make the inspection of trucks; all study case considers the use of existing ITS infrastructure, as well as the deployment of new infrastructure. In order to implement the IoT, the study case use the RFID (Radio Frequency Identification) technologies associated with sensors installed at vehicle in order to identify the vehicle when it pass through a portal and the associated information, if available, as: temperature, average velocity, doors and others relevant information. The advantage of IoT is the ability to identify the vehicles and other information without disrupting the normal flow.
