CARBON AND FUEL FROM RUBBER WASTE
Authors: Zhuravsky Gennadi I. , Nitievski Maksim I.
Published: March 2021

The results of studies of thermolysis waste in the environment of overheated water vapor are presented. It is shown that as a result of fractionation from liquid waste thermolysis products, gasoline and diesel fuel fractions can be obtained. It is proposed to use a composite mixture of liquid and solid waste thermolysis products as raw materials for high-grade technical carbon. Studies have shown that high-grade technical carbon can be obtained as raw materials using a composite mixture of rubber waste thermolysis products as raw materials. The technological line of obtaining technical carbon from the products of thermolysis of worn tires is described. Analysis of the ash produced by the process of burning the composite mixture shows that it contains compounds of iron, zinc and silicon. Therefore, this ash is of interest as a high-quality raw material for the production of zinc oxide, as one of the main ingredients of rubber mixtures.

Introduction. The development of modern society implies that more and more information is placed in the digital space. Therefore, the attitude of the management of transport companies to the promotion of healthy lifestyle and the prevention of COVID-19 can be indirectly assessed by the content of their sites and web pages. Purpose. The purpose of this article is a content analysis of rail companies’ sites and web pages on the promotion of healthy lifestyles and the prevention of COVID-19. Materials and methods. The study was carried out once, in October 2020. We analyzed the sites and web pages of rail companies using the formation of queries, as well as using the search engines Yandex and Google. Results. The frequency of mentioning healthy lifestyle issues on the websites and web pages of the analyzed rail companies vary from 32 to 54 %. COVID-19 prevention issues are covered only in a half of cases by railway companies and in more than 90 % – on the websites and web pages of subways, high-speed trams and city trams. In general, the analyzed websites and web pages of the rail companies adequately display the information related to the prevention of COVID. Discussion. Rail companies pay attention to the formation of healthy lifestyles and prevention of COVID-19 on their web pages and sites. For this reason, it can be assumed that the management of the rail companies is concerned about these problems. At the same time, we have no reason to believe that the analyzed web documents fully reflect the ongoing preventive programs, in other words, it can be assumed that the preventive activities of rail companies are broader than shown in this study. Meanwhile, rail companies do not fully cover their social policy regarding the health of their own employees. Conclusion. The sites and web pages of rail companies, as a rule, contain scattered information on promoting healthy lifestyle. At the same time, the information on the prevention of COVID-19 is usually presented in a comprehensive manner. The issues of COVID-19 prevention in general are mentioned on more sites and web pages than the issues of healthy lifestyle formation.

Authors: Burdastova Yulia V.
Published: March 2021

The article provides an overview of the European experience in changing the role of a nurse, as well as Russian practices within the framework of a pilot project to expand the functions of nurses in accordance with the order of the Ministry of Health of Russia "On the approval of an action plan («road map») to expand the functions of specialists with secondary medical education. The author emphasizes that the new challenges of the millennium entail a shift in emphasis towards patient orientation, which implies an improvement in the quality of medical services, and this, in turn, will address the issues of competent distribution of powers between doctors and nurses. The article notes that patient-centered medical care entails an increase in the burden on nurses and their empowerment. The author analyzes both the advantages of expanding the role of nurses: career advancement with continuous professional and personal development through the acquisition of additional knowledge and competencies, and possible risks: psychological resistance of doctors and nurses to new forms of work, conflict of interests between doctors and nurses, unwillingness of nurses to work with documents, etc.
The Impact of Pandemics on Workforce Joblessness in Central Europe in pre-Covid Era and during Pandemic
Authors: Beno Michal
Published: March 2021

Unemployment affects individuals socially, personally, and economically. The impact of being jobless can be long-lasting. Five different generations participate in the workplace today. As countries throughout the world went into lockdown to combat the spread of Covid-19, unemployment numbers rose rapidly. This study aimed to examine the effects of unemployment in three-generation groups in V4 and Austria in the pre-Covid-19 era and during Covid-19. Descriptive statistics were used to present the collected data. OECD data were used for the analysis. Based on the data collected, unemployment decreases with age. The group aged 15-24 shows significantly higher unemployment than the other two groups. A gender difference in unemployment was confirmed only in the Czech Republic and Slovakia. Unemployment has increased during the Covid-19 pandemic. The unemployment gap for females before and during Covid-19 was not confirmed. The T-Test confirmed the difference in unemployment before and during the crisis in the age categories 15-24 and 25-54. In Hungary, Poland, and Slovakia, the number of people with a duration of employment of up to one year differs in all age categories. In the Czech Republic, there is a significant difference only between the youngest group and the other two. In all countries, the largest number of people with the employment of up to one year is in the age group 25-54. In none of the examined countries was a gender unemployment gap proved before Covid-19.

"Shepherding on Argeș Valley – spatial coordinates

This paper presents the essential elements that define the spatial coordinate characteristic of shepherding which is practised in the sub-Carpathian villages on the Argeș Valley, following the documentary attestations of the villages, the genesis and evolution of the village boundaries, the evolution of land ownership and the right to use lands (in condominium or individually). Also within the spatial coordinate, there are researched the traditional ways in which the potential of the rural land fund is highlighted, as a result of its geomorphological, pedological, climatic qualities, etc., the study taking into consideration all the areal types with pastoral potential, not only those on the administrative territory of the villages, but also those in the mountain area destined for summer grazing.
If for the presentation of origins, attestations, borderline fixation of the villages from the studied areal, documents, monographic studies and other categories of specialized works have been used, for the understanding of the manner of pastoral, individual and especially collective exploitation of the land fund by the village communities, of valorizing the fodder qualities of the different types of surfaces, it was necessary to carry out field research in the three targeted villages: Albeștii de Argeș, Corbeni and Arefu, all in the Argeș County. The visit of sheepfolds from Lespezi, Lipitoarea, Ciocanu, Podeanu, Oticu, in the alpine hollow of the Făgăraș Mountains, were necessary both for studying some elements related to the spatial coordinate (sheepfold location, daily travel routes, travel routes from the village hearth to the mountains, etc.) as well as for conducting interviews, based on an elaborate questionnaire, interviews generating unique and extremely useful information also for researching the other coordinates of the pastoral system practiced in the area.

In recent days, increasing numbers of Internet and wireless network users have helped accelerate the need for encryption mechanisms and devices to protect user data sharing across an unsecured network. Data security, integrity, and verification may be used due to these features. In internet traffic encryption, symmetrical block chips play an essential role. Data Encryption Standard (DES) and Advanced Encryption Standard (AES) ensure privacy encryption underlying data protection standards. The DES and the AES provide information security. DES and AES have the distinction of being introduced in both hardware and applications. DES and AES hardware implementation has many advantages, such as increased performance and improved safety. This paper provides an exhaustive study of the implementation by DES and AES of field programming gate arrays (FPGAs) using both DES and AES. Since FPGAs can be defined as just one mission, computers are superior to them.

Published: March 2021

En Ecuador los delitos de violencia contra la mujer cada vez van en aumento considerando a la violencia como una prioridad a nivel salud pública, política, científica y social; teniendo como eje principal la erradicación de este fenómeno surge la necesidad de estudiar al agresor; su personalidad y las diferentes variables psicológicas (distorsiones cognitivas) a fin de generar tratamientos especializados encaminados a mitigar esta problemática.  La presente investigación tiene como objeto analizar los rasgos de personalidad y distorsiones cognitivas en relación a la mujer y el uso de la violencia. Los instrumentos utilizados son el IPDE “Examen internacional de los trastornos de la personalidad” y el IPDMUV; Inventario de pensamientos distorsionados sobre la mujer y el uso de la violencia (IPDMUV –R; Echeburúa, Amor, Belén Sarasua, Irene Zubizarreta y Francisco Pablo Holgado-Tello   2016). La población de estudio estuvo conformada por 95 sujetos privados de la libertad del Centro de Rehabilitación Social de Cañar. El estudio refleja una población con una edad media de 39 años, nivel de instrucción básica en el 93,68% de los sujetos y pese a la variedad de delitos cometidos se destaca que en el 49,48% de ellos la victima ha sido una mujer entre estos; violación, femicidio, acoso sexual, incumplimiento de decisiones, violencia física. Entre los rasgos de personalidad que sobresalen el 20, 00% muestra rasgos evitativos y el 16,8% rasgos histriónicos de la personalidad, otro de los hallazgos es que a mayor edad del sujeto las distorsiones cognitivas disminuyen y finalmente y en correspondencia con la citada teoría el 75,79% consideran que lo que ocurre dentro de una familia es problema únicamente de la familia.

Los programas sociales, como iniciativa orientada a mejorar la calidad de vida de la población, representan siempre un gran desafío para la planificación de los gobiernos, destacando el gran requerimiento de recursos para su ejecución, que, en este ámbito, siempre resultarán limitados.  Con la finalidad de maximizar las posibilidades de alcanzar las metas establecidas, surge la concepción de alianza estratégica que para este trabajo se centre entre el estado y la academia. El Ministerio de Inclusión Económica y Social (MIES), impulsa acciones para dar mayor protagonismo y participación a la población juvenil en la generación de las políticas públicas. En el año 2015 se implementó la misión “Leónidas Proaño”, para vincular a los estudiantes universitarios a los servicios institucionales para ejecutar sus prácticas pre-profesionales. La Unidad Académica de Salud y Bienestar de la Sede Azogues, en respuesta a los requerimientos del Distrito 1 del MIES Azogues, planificó la ejecución del proyecto Intervención en salud de niños, niñas y familias del Programa Creciendo con Nuestros Hijos,  con el objetivo de contribuir a mejorar la condición de salud de los niños y niñas que asisten a este programa. Entre los participantes se cuentan

estudiantes de Medicina, Enfermería, Biofarmacia, docentes de la UCACUE, educadoras, niños de 0 a 60 meses y padres de familia del programa Creciendo con nuestros Hijos. El valor de asociarse ha permitido proyectar una mayor visibilidad de actividades de vinculación con la sociedad entre los que se destacan: 2313 niños evaluados en su estado nutricional, desarrollo, pruebas de hemoglobina y exámenes copro-parasitarios. Adicionalmente los padres y/o representantes han recibido educación para la salud en alimentación complementaria, prevención de infecciones y de infecciones.

Application of Cluster Analysis to Define Level of Service Criteria of U-turns at Median Openings
Authors: Mohapatra Smruti Sourava
Published: March 2021

Defining Level of Service (LOS) criteria of U-turns is important for proper planning, design of transportation projects and also allocating resources. The present study attempts to establish a framework to define LOS criteria of U-turns keeping in mind the peculiar behavior of drivers and heterogeneity in urban Indian context. The U-turns at uncontrolled (no traffic sign, no signal, no traffic personnel) median openings are very risky. Upon arrival at the median opening, the U-turning vehicle looks for a suitable gap in the approaching traffic stream before initiating the merging process. While waiting for a suitable gap the U-turning vehicle experiences service delay. This service delay has been studied to quantify the delay ranges for different LOS categories. In this study, service delay data were collected from 7 different sections and microscopic analysis procedure was adopted to extract data from the recorded video. Subsequently, clustering technique has been utilized to defining delay ranges of different level of service categories. Four clustering methods, namely; K-mean, K-medoid, Affinity Propagation (AP), and Fuzzy C-means (FCM) are used. Four validation parameters are applied to determine most suitable clustering algorithm for the study and to determine the optimal number of cluster. AP was found to be the most suitable clustering method and 6 was found to be the optimal number and accordingly the collected delay data were clustered into 6 categories using AP. The delay range is found to be less than 4 s for LOS A is greater than 35 s for LOS F.

Introduction

To investigate the imaging features of emerging COVID-19 pneumonia on chest ultrasound, radiographs and computed tomography examinations performed at admission. In addition, we provide a review of the literature and compare our results with recent evidence regarding the imaging characteristics of this novel disease.

Material and methods

From March 17, 2020 to April 25, 2020, 23 patients with real-time polymerase chain reaction (RT-PCR) assay confirmed COVID-19 were identified. All 23 patients were evaluated and admitted at San Giuseppe Moscati Hospital in Aversa, Italy. Multi-modality imaging findings were evaluated and compared. Literature research was conducted through a metho­dical search on PubMed.

Results

Twenty-three patients were included in the study. Chest transthoracic ultrasound (US), chest X-ray (CXR), and computed tomography (CT) were performed respectively in 11, 16 and 21 patients. Chest US findings were consistent with diffuse B lines (91%), subpleural consolidations (45%), and thickened pleural line (18%). CXR showed prevalent manifestations of consolidations (50%) and hazy increased opacities (37%). Typical CT features are bilateral and multilobar ground-glass opacities (GGO). Indeed GGO were present in 100% of our patients. Consolidations were visible in 76% of our study population. Notably both GGO and consolidations had a peripheral distribution in all our patients. Other CT imaging features included crazy-paving pattern, fibrous stripes, subpleural lines, architectural distortion, air bronchogram sign, vascular thickening and nodules. Our literature review identified thirty original studies supporting our imaging chest findings.

Conclusions

At admission, COVID-19 pneumonia can manifest in chest imaging as B-lines and consolidations on US,
hazy opacities and consolidations on CXR, multiple GGO and consolidations on CT scan.

Published: March 2021

Introduction

The aim of this study was to evaluate how chest computed tomography (CT) can predict pejorative evolution in COVID-19 patients.

Material and methods

Data on 349 consecutive patients who underwent a chest CT either for severe suspected
COVID-19 pneumonia or clinical aggravation and with COVID-19 were retrospectively analysed. In total, 109 had laboratory-confirmed COVID-19 infection by a positive reverse-transcription polymerase chain reaction (RT-PCR) and were included. The main outcomes for pejorative evolution were death and the need for invasive endotracheal ventilation (IEV). All the CT images were retrospectively reviewed, to analyse the CT signs and semiologic patterns of pulmonary involvement.

Results

Among the 109 COVID-19 patients, 73 (67%) had severe symptoms of COVID-19, 28 (25.7%) needed an IEV, and 11 (10.1%) died. The following signs were significantly associated with both mortality and need for IEV: traction bronchiectasis and total affected lung volume ≥ 50% (p < 10–3). Other CT signs were only associated with the need of IEV: vascular dilatation, air bubble sign, peribronchovascular thickening, interlobular thickening, and number of involved lobes ≥ 4 (p < 10–3).

Conclusions

On a chest CT performed during the first week of the symptoms, the presence of traction bronchiectasis and high values of affected lung volume are associated with the need for IEV, and with mortality, in COVID-19 patients.

Dayah is a traditional Islamic educational institution in Aceh that gave birth to scholars to enlighten the people. Today's developments require dayah to continue to exist, giving generations of morals. This research is a qualitative research with a social history approach. The findings concluded that basically the community's anxiety due to the dominance of materialism which makes the soul arid, has provided opportunities for people to look for institutions. The modernization that has been carried out is still based on the original tradition, which is based on dayah with a modern twist so that the dayah is MUDI. The modernization of the dayah education system during the Abon Abdul Aziz era included modernizing the curriculum, facilities and infrastructure and modernizing learning methods. The purpose of this change is so that the dayah will continue to exist in this era of globalization so that the vision of giving birth to scholars is still running. The dayah education system managed by Abon Abdul Aziz remains in control to shape the morals of thalabah so that the knowledge obtained in the dayah is still used in terms of goodness. Through the touch of moral education to the talabah who studied in the dayah, most of the istiqamah studied until they got permission from Abon Abdul Aziz to practice their knowledge in the community.

Published: March 2021

This study aimed to explore a comprehensive model to address the indirect impact of transformational leadership (TL) on employee creativity (EC). Study proposed three serial mediators; innovation climate (IC), creative self-efficacy (CSE), and follower relational identification (FRI). A self-administered questionnaire survey was conducted from employees of IT and telecom sector. Smart PLS-SEM 3.2.9 was used to measure direct and indirect analysis. The findings of this study reveals a positive link between TL and EC. Moreover, IC, CSE and FRI is found to mediate the direct relationship. The present study contributes to the existing literature by identifying the missing links in the form of IC, CSE, and FRI between TL and EC. More mechanisms are suggested to enrich the existing framework by adding mediators as well as moderators. As results show that EC is promoted through TL, so findings are valuable for managers to invest in training of supervisor’s TL to find out the extent of potential to become a TL. The study suggested the dire need of organizations to focus on inculcating innovation climate in order to achieve desired creativity results.

The study examines the relationship between job stress and turnover intentions with the moderating role of emotional intelligence. The questionnaire survey is conducted with a sample of 153 employees of the banking sector in Pakistan. Two methods are used in this study to test the moderation effect i.e. Baron and Kenny’s (1986) technique and the Process method of Andrew F. Hayes (2013). The results show that job stress and turnover intentions are positively related to each other whereas emotional intelligence has no moderating role between them. Based on the findings, it is proposed that organizations should focus on making active policies towards stress management so that employees’ turnover intentions can be reduced ensuring an encouraging working environment.
Relationship between Capital Structure and Profitability: Dual Banking Perspective
Authors: Zaman Mudassir , Ullah Shakir , Ali Arshad
Published: March 2021

This study looks into the relationship between the capital structure and profitability of Islamic and conventional banks, listed on the Karachi Stock Exchange extracting data for 250 observations between 2006 and 2016 from their financial statements. The paper uses regression analysis to check the proposed relationship. We found a strong correlation between Debt-to-Equity (D/E) ratio and Return on Equity (ROA) in conventional banks while no significant relationship existed in Islamic banks. The findings can be explained in terms of the different deposit mechanisms employed by the two systems i.e. the conventional banking system considers all deposits as liabilities of the banks while on the other hand Islamic banks only write the current accounts as a debt. The Modaraba-based deposit accounts of Islamic banks are considered as equity. This paper contributes theoretically to the current body of Islamic finance literature in Pakistan. On the practical side, the study suggests that Islamic banks can increase their savings deposits as they pose no risk and have equity-like features.

The study aims to examine what causes firms to engage in Corporate Social Responsibility (CSR) Decoupling. It also highlights the intensity of the firms to be involved in the decoupling of firms’ actual from claimed CSR practices. The study hypothesizes a significant association between CSR decoupling and its various antecedents. The documented antecedents are coercive isomorphism, monitoring mechanism, firm reputation, resource slack, and firm advertising intensity. Based on Institutional Theory and Stakeholder Theory, the present study accounts for the gap between firms’ actual CSR efforts and its professed CSR while also highlighting the factors and conditions under which firms overstate and misrepresent their CSR activities. The sample of the study includes 200 non-financial Pakistani firms listed on Pakistan Stock Exchange (PSX) with a time frame ranging from 2010 to 2018. The model under study is tested using common effects regression. The study findings reveal that non-financial firms operating in Pakistan are highly engaged in CSR decoupling. Also, coercive isomorphism, monitoring mechanisms, and firm reputation are significantly associated with CSR decoupling.
