COVID-19 NATIONWIDE LOCKDOWN OF 2020- OBSERVATIONS ON PROMINENT POLLUTANT IN THE COASTAL CITIES OF CHENNAI AND MUMBAI
Authors: Puri Priyanka
Published: January 2022

The pan-India Lockdown of 2020 due to COVID-19 pandemic as a turning point in impacting the environment and generating new trends lends it to specific analysis. In this context, the urban scenarios are most widely discussed and the Indian metropolitan cities stand pertinent examination. While many studies exist on analyzing air quality and air quality parameters in distribution and varying trends, works on highlighting the nature of dominant pollutant in time and space is not observed. The current study is distinctive in method as it tends to observe the evolving nature and distribution of primary pollutant in the air of two coastal cities of Chennai and Mumbai for every day of the COVID-19 nationwide Lockdown period of 2020. A comparative analysis is further attempted by taking air quality data for the period of national Lockdown in the matrix of 92*7 plus 92*4 time periods for Mumbai and Chennai respectively. Results reveal that despite being coastal in location, both cities have a distinct nature and distribution of Prominent Pollutant during this period. An examination of such a kind is pertinent in outlining the nature of pollution and its geographical dimensions across an urban area. This can help in the observation and management of pollution problem in a practical dimension.

Political-Pedagogical Character of the Collective Actions of the Popular Bars
Authors: Díaz Alzate Magda Victoria , Menjura Acosta Juan Pablo , Fonseca Echeverri Maria Clara
Published: January 2022

Barrismo is a complex phenomenon and cannot be defined universally. Social representation is based on deficient conceptions that relate it to the use of psychoactive substances and violence. This article presents qualitative research evidence based on the epistemological assumptions of social constructionism, a hermeneutical phenomenological design and the use of qualitative interview and documentary and audiovisual review, to understand the political-pedagogical character of the collective actions of the popular bars of the city of Medellín, Colombia, as practices that contribute to the transformation of the territories. Categories found: i. Bars as popular movements: transition from the brave bar to the popular bar, and ii. Collective actions: Barrismo Social. The bars have gone from rough bars to popular bars, from political and critical reflexivity, with collective actions for the transformation of the territories, which transcends the experience of stigma and social prejudice.
Embracing a Culture of STEM Education: A Qualitative Research Study
Authors: Laux Katie
Published: January 2022

The purpose of this study was to explore teacher and administrator perspectives on STEM education and how they demonstrate characteristics of STEM education. The five schools in this study are part of a greater network of elementary, middle, and high schools that collaborate and learn together. Data were collected through interviews with teachers and administrators and observational notes from meetings and other events. Interviews were recorded and transcribed and then coded to look for themes in the data. Findings indicate teachers and administrators view a supportive leadership, teacher buy in, and comfort in teaching STEM as essential to the implementation of STEM initiatives. Without these necessary components, inequities may arise and lead to less opportunities for students. Overcoming obstacles may require a change in mindset to embrace a culture of STEM teaching and learning. Understanding how teachers and administrators view the importance of STEM and benefits of participating in a community of STEM can help understand how to shift the culture of a school to one more inclusive of STEM education.

Authors: Kok Jin Kuan , Khor Khengkia , Hon Kai Yee , van Schalkwyk Gertina
Published: January 2022

The percentage of refugee children in Malaysia has been growing in recent years with a rise of more than 9000 in less than 3 years. More than 51,000 of the 164,620 documented refugees in 2019 are below the age of 18 years. Refugee children are often marginalized in society making them vulnerable and requiring special assistance in meeting their educational needs, mental health care and socio-emotional wellbeing. The purpose of this study was to discover the perceptions of refugee children regarding family life and their emotional and coping mechanisms. Employing the Collage Life-Story Elicitation Technique (CLET) and a discovery-oriented narrative approach, 25 refugee children at a non-governmental educational center in Kuala Lumpur were interviewed. The findings from an in-depth thematic analysis revealed that these refugee children perceived their families as having gone through separation and disruption resulting in isolation, loneliness and being powerless in the host country. Their coping mechanisms included help offered by enabling adults, teachers seen as angels and other wise people from the community who were their sources of strength. They strived for a better future through being brave and independent. We also discuss the need for more humanitarian programs and support for this group of vulnerable children in Malaysia.
Nudos, tensiones y desenlaces de los trabajos maternos: capturas desde los contextos digitales
Authors: Echeverri Gallo Catalina
Published: January 2022

La mayor incorporación de las mujeres al mercado laboral desde mediados del siglo XX, derivada de las conquistas feministas, no se ha dado en condiciones de igualdad con los hombres; por el contrario, es un escenario en el que se reproducen las disparidades de género, de manera naturalizada y subrepticia, en especial si se es madre. En la contemporaneidad, las mujeres se han apropiado, cada vez más, de las herramientas y los escenarios digitales como parte de sus mundos cotidianos, de allí que los análisis sociales sobre los trabajos maternos deban acoger el estudio de estas nuevas matrices relacionales que las mujeres habitan y transitan. A partir de una etnografía digital y los aportes de los feminismos y las ciencias sociales, busco aportar a la comprensión de las subjetividades que configuran los discursos hegemónicos desde los trabajos dictaminados para las madres, los cuales pueden ser capturados en las interacciones que despliegan siete madres blogueras colombianas y las comunidades que las siguen en sus trayectorias. Los resultados muestran que las mujeres a través de las mediaciones digitales entrevén los nudos y las tramas que el sistema patriarcal y capitalista les imponen a las madres para ingresar, sostenerse y desplegarse en el ámbito laboral por fuera del hogar, y cómo se ingenian maneras para conciliar sus trabajos remunerados y no remunerados desde sus alcances individuales, omitiéndose las estructuras que subyacen. En estos intentos de conciliación se inscribe la generación de contenidos en las plataformas digitales como una forma de trabajo por parte de las madres blogueras; sin embargo, estos discursos también son cuestionados y resignificados por medio de las narrativas y las prácticas digitales lo que posibilita la emergencia de otras subjetividades y devenires maternos.
PTICE U PROSTORNIM I VREMENSKIM MODELIMA USMENE LIRIKE
Authors: Vukmanović Ana
Published: January 2022

The paper shows how human experience of nature influences poetic of oral lyric, more precisely – formation of spatial and temporal models. The functions of birds in these models are determined by their characteristic of flying and singing. Birds have an important role in constructing cosmic notions (axis mundi, hierogamic union, celestial world and master of rain). As ambiguous, birds belong to tame and wild, human and inhuman world. They can easily cross the boundaries in both directions – they arrive from the other world in the human world, and fly away from the human world to the ulterior one. They connect different spheres by their flight or voice – sky and earth, earth and water, mountain, water and field. Birds can equally belong to the far away spaces and the space of home. They mark crucial moments, tem- poral boundaries and intervals within the temporal models, but they are most often associated with morning and magical clean time. On the other hand, the songs model year cycle by the motif of migration of birds. As a part of one’s own and alien world, birds are important part of notion of nature in oral lyric songs.

Authors: Lagat Nicholas , Oyore J , Korir J.
Published: January 2022

Purpose: Malaria remains to be among the primary causes of sickness, infirmity and cases of deaths and has continued to negatively affect health and socio-economic progress in the country. Rapid reporting of malaria cases could avert prospective epidemics which would lead to a high proportion of sickness and deaths. The study, therefore, sought to assess the determinants of malaria routine data reporting among health workers in selected health facilities in Trans-Nzoia County.

Methodology: A descriptive cross-sectional study was conducted to evaluate the organizational, technical, and behavioral aspects that influence the reporting of malaria routine data among health workers. The sample size was 123 health facilities that were selected randomly based on their strata. Research tools that were utilized were structured questionnaires, focused group discussion, and key informant interview guide.  Chi-square (χ2) was used to test the hypothesis with a p ≤ 0.05 being considered significant.

Findings: The findings on socio-demographic characteristics indicated that majority of the research participants were females 76(62.6%), had college education 85(69.1%) and 81 (65.9%) had worked in the health facility for 5 to 10 years. Most 76(61.8%) of the health facilities were Level 3 (Health Centres). There was significant relationship between level of health facility and malaria routine data reporting at (χ2 =9.999, df=3, p-value = 0.019). Other organizational factors that had significant association with malaria routine data reporting (p< 0.001) include inadequate budget, low staffing, poor ICT infrastructure and complex data management procedures.  In terms of technical aspects, limited training on technologies had significant relationship with malaria routine data reporting (p< 0.001). Regarding behavioral aspects, identified factors include lack of incentives and inadequate resources.

Unique contribution to theory, practice and policy: The outcomes of the study provide proof for support, tactical organization, and collaboration in the health sector in Trans-Nzoia County as well as to the other developmental agencies working in the field of malaria control. The study recommends that the county government of Trans-Nzoia should provide adequate funds and ICT infrastructure to boost malaria routine data reporting. The county department of health with support from the national government through Division of National Malaria Program (DNMP )should consistently conduct in-service training, support supervision and data quality audits.

Authors: Phuong Vu Thi Thuc , Tam Bui Duc , Thanh Tran Cong
Published: January 2022

Pain after cardiac surgery is always an obsession of patients and a top concern of anesthesiologists. Experimental subjects challenged by acute pain and patients in chronic pain experience impairments in attention control, working memory, mental flexibility, problem solving, and information processing speed. The two most commonly used analgesia methods are patient-controlled analgesia (PCA) and erector spinea plane block (ESP). Our study aimed to compare the analgesic effect of ESP with PCA in patients after cardiac surgery using extracorporeal circulation and evaluate the disavantages of these two pain relief techniques. Subject and methods: This study was a randomized controlled intervention study of adult patients who underwent open-heart surgery patients with extracorporeal circulation from May 2020 to September 2021 in the Department of Anesthesiology and Intensive Care Unit - Hanoi Heart Hospital. Results: Two hundred and four (204) consecutive patients were collected, included 108 patients in the ESP group and 96 patients in the PCA group. The mean intraoperative fentanyl amount in the ESP group (0.57±0.50 mg) was lower than in the PCA group (1.00±0.00 mg) (p<0.05). The average VAS score when the patient was lying still and taking deep breaths at the time of assessment in both groups was below 3 (corresponding to low pain level) (p>0.05). The mean morphin consumption 24 hours after surgery was significantly lower in the ESP group (0,23±0,12 mg) than in the PCA group (17,92±3,32 mg) (p<0.05). The mean time after surgery in the ESP group (3.80±1.02 hours) and the PCA group (5.21±1.10 hours) had a clear difference between p<0.05. The mean time of extubation in the ESP group (8.06±1.60 hours) was statistically significantly lower than in the PCA group (8.83±1.43 hours) (p<0.05). The rate of nausea in the ESP group (20.98%) was lower than in the PCA group (58.33%) (p<0.05). Conclusion: Both methods had good analgesic effect with an average VAS score ≤ 3. The ESP group had a lower mean postoperative morphine consumption, a higher patient satisfaction level, and a lower rate of nausea, vomiting, and slow breathing statistically significant less than the PCA group.

Authors: Thanh Ngo Van , Son Pham Truong , Tuan Nguyen Quang
Published: January 2022

Introduction and objectives: Previous studies have shown that after coronary artery bypass grafting (CABG), heart rate variability (HRV) becomes decreased. The loss of the peripheral autonomic sympathetic and parasympathetic control in Sinoatrial Node in the form of an autonomic cardioneuropathy syndrome is the predictor of the pre and postoperative complications after CABG. The aim of this study was to establish the temporal pattern of change in the decrease of HRV observed after CABG. Methods: The study involved 119 consecutive patients who underwent the first CABG operation with sinus rhythm. All subjects underwent assessed with 24-hour Holter recordings 2 days preoperative and 7 days, 3 months, 6 months postoperative at Hanoi Heart Hospital from 6/2016 to 8/2018. Main results: All indicators of heart rate variability decreased to the lowest level after surgery 7 days, recovers to the preoperative values within three to six months of the procedure. The incidence of pre and postoperative low HRV varies from 28.6% (preop) to 51.8% (postop 7 days), 19.6% (postop 3 months) and 12.7% (postop 6 months). Conclusions: This study have showed that CABG surgery generally leads to significant reduction in HRV. HRV gradually recovers to the preoperative values within three to six months of the procedure.

Authors: Bhatt Megha , Vasanwala Sandip
Published: January 2022

Diffusion of gaseous and particulate pollutants from tall stacks has formed an important element in the control of air pollution since the industrial revolution began. These tall reinforced concrete chimneys are considered to be cantilever columns subjected to axial load resulted from the self-weight of the shell, linings and other accessories and bending moments which are resulted from the lateral loads like wind forces and earthquake forces.

The recently published IS: 4998 – 2015 adopted a limit state design concept which requires well defined stress-strain relationship for concrete and steel. It has been seen that there are many disparities lies between the stress-strain relationships of constituent materials adopted by IS: 4998 – 2015 and other design standards.

This paper discusses various methods pertaining to the estimation of the ultimate strength of thin-walled hollow circular sections of reinforced concrete chimneys, subjected to wind loading. A comparative study of various methods based on the prevalent codes reveals considerable disparity in the predicted ultimate strength values. These differences have been critically analyzed and results are discussed in this paper in terms of ultimate strength along with the contribution of concrete and steel, ultimate curvature and depth of neutral axis. For the comparison of above-mentioned parameters, design recommendations of IS 4998 – 2015, CICIND 2011, ACI 307 – 08 are used.

Authors: Reza D. S. A. Aashiqur , Billah Md. Noman , Shanta Sharmin Sultana
Published: January 2022

When a pandemic occurs, it can cost fatal damages to human life. Therefore, it is important to understand the dynamics of a global pandemic in order to find a way of prevention. This paper contains an empirical study regarding the dynamics of the current COVID-19 pandemic. We have formulated a dynamic model of COVID-19 pandemic by subdividing the total population into six different classes namely susceptible, asymptomatic, infected, recovered, quarantined, and vaccinated. The basic reproduction number corresponding to our model has been determined. Moreover, sensitivity analysis has been conducted to find the most important parameters which can be crucial in preventing the outbreak. Numerical simulations have been made to visualize the movement of population in different classes and specifically to see the effect of quarantine and vaccination processes. The findings from our model reveal that both vaccination and quarantine are important to curtail the spread of COVID-19 pandemic. The present study can be effective in public health sectors for minimizing the burden of any pandemic.

The producers, intermediaries, shippers, and consignees, located often thousands of miles distant from each other, require efficient transport and logistics services to get the right product with the right quality and quantity to the right place within the right time and above all at a right price. The main objective of this study was to assess the effect of freight transport service performance on international trade competitiveness. A descriptive research design was used. Secondary data were collected from international organizations' policy, standards documents, and annual report of the year 2018 by using the Logistic Performance Index rank. Moreover, a quantitative research approach was applied. The data were entered, manipulated, organized, and analyzed using Excel and Statistical Package for Social Science. Both descriptive and inferential analyses were used to identify and examine the extent of international trade competitiveness and its implication in the global market. As the result reviled the entire logistic performance factors such as Growth Domestic Product, Distance, Infrastructure, Landlocked, and Timelines were found to be significantly important to determine the global market competitiveness. But, the geographical distance between bilateral countries affected a country’s trade negatively. The top 10 higher Logistic Performance Index scores more competitive and better implementer of the effects of freight transport factors; whereas, the bottom scorers had an ineffective market link with their partners.

The main aim of this research paper is to examine the trade-off between liquidity and profitability of Indian firms. The target population of the study is manufacturing firms. The study used convenience sampling for collecting the data. The study is based on secondary data for the period from 2008 to 2017 and 20 Indian manufacturing firms are selected for this purpose. Analysis of the data has been undertaken using SPSS software. Findings revealed that current liabilities ratio have a positive and significant impact on earnings per share and profit after tax. On the contrary, the current ratio and quick ratio have an insignificant impact on earnings per share, return on capital employed, return on assets and profit after tax. This study suggests that managers should incorporate liquidity into their evaluation decisions in order to boost the financial return of their businesses. The current study offers valuable insights into the success of Indian listed companies for administrators, analysts, regulators, investors, and other interested parties. There is insufficient research that has been conducted to examine the trade-off between liquidity and profitability. Furthermore, findings from this literature cannot be relied upon as they are outdated. Therefore, this study is going to provide updated evidence on the trade-off between liquidity and profitability of Indian manufacturing firms, an area that has largely remained unexplored.

Authors: Oloo Oloo
Published: January 2022

In recent years, the Chinese media has grown vastly with the country’s interest in the investment in the developing countries. As the relationship with these countries become, so as the influence of Chinese culture towards the nations through the ever-growing Chinese media. Since the implementation of significant projects in Africa, Caribbean and Asia countries by Chinese government, the Chinese media have been characterized in localizing their TV contents to compete with the host countries and stretching their sense of soft power to these nations. Although they have faced significant challenges in terms of cultural difference, and technological development, the Chinese reality TV shows have continued to be part of the regular host countries' TV program diet while facing fierce standpoint from the initial global dominant media in these markets. This paper analyses these trends in focus on the Chinese reality TV shows that have hit the host countries' market as well as the motivation of their evolution. The article traces the extent of these strategies to be leveraged by states to balance their local production and foster cordial relation with China in a context of edutainment. It is imperative to analyze the development of this crucial phenomenon in the ontological perspective of the internationalization and marketization of products. The article addresses these issues by drawing attention from different players in this conspicuous field.
Collective actions for reconfiguration of urban space Biały Bór, Poland
Authors: Ilchenko Sergiy
Published: January 2022

Biały Bór is located in the former German territories that came to Poland after the Second World War. The almost complete replacement of the indigenous German and Jewish populations, initially by Polish and soon Ukrainian communities, was the result of the displacement of state borders by the eviction and relocation of millions of people. To do this, the authorities used certain strategies, which brought different approaches and constraints to local communities and urban spaces. The article considers the differences between the declared principles and the actual actions of the authorities in the context of “small stories” of all actors (national communities), as well as the tactics of indirect resistance of the local community to government pressure. Due to the remoteness of the place from the state center and due to its unanimity, the local community becomes the driving force of the spatial development of the city. And since the city is multicultural, the development of public spaces is influenced by the competitiveness (not confrontation) of two local communities. Therefore, the creation of public spaces is considered in the context of the rights of different groups to the city. This paper argues the conditions under which it is the collective actions of local communities that determine the change in the configuration of urban space.

To design architectural spaces that not only respond to the basic needs of users, but also seek their emotional well-being, it is necessary for the architecture students to have a special sensitivity and be aware of the different sensations that their designs should and can evoke. To achieve this competence without exploring real spaces, Immersive Virtual Reality technology offers an important contribution to the field of architecture. The purpose of this research is to determine if the sensations perceived in virtual architectural spaces by students are similar to the real ones and to determine the characteristics of this technology that allow a better perception of sensations. Six architectural modules were designed to be walked through and experienced at real scale using a Head Mounted Display by 22 students of the first and fifth year of studies of Architecture career in Peru. An ad-hoc questionnaire allowed to know the perceived sensations and the benefits of the tool. The results obtained showed that the perception of sensations of the fifth year students is a little closer to those expressed by a group of seven experts compared to that of the first year students and that the students consider the characteristics of accessibility, real scale of the space and the possibility of going through and looking at the space in all directions are those that have given more realism to the experience and therefore better perception of the space, while the characteristics of natural light and shadows, construction materials and external environment have been less valued in the realism of the experience. It is concluded that the sensory experimentation in architectural spaces modelled realistically in virtual environments allows the perception of sensations very similar to those that the architect seeks to convey initially.
