Indigenous Birth Support Worker (IBSW) Program Evaluation: A Qualitative Analysis of Program Workers and Clients’ Perspectives
Authors: Pandey Mamata , Smith Leanne , Maczek Nicole , Sasakamoose JoLee , Tomkins Angela
Published: October 2022

Background:
The Indigenous Birth Support Worker (IBSW) Program provides indigenous women with respectful, culturally safe, and trauma-informed care and supports women and families during labor and delivery. Located in the Jim Pattison Children’s Hospital (JPCH) Maternal Care Centre in Saskatoon, Saskatchewan, Canada, the program served 1023 clients between December 2019 and January 2021.
Methods:
The study objective was to explore the perspectives of the IBSWs and program clients one year post-implementation. The research plan was developed in collaboration with the IBSW program director and manager, IBSWs, and partners from the First Nation and Métis Health departments within the health region.
A focus group with four IBSWs and individual interviews with ten clients who received services were conducted using a qualitative research design.
Results:
Thematic analysis revealed that clients greatly appreciated and respected the IBSWs’ cultural support and their compassionate, nonjudgmental, and safe care. IBSWs emphasized the importance of culturally safe and client-centered treatment, more effective pain management solutions, and that relationships with elders and community healthcare personnel should be built and strengthened to improve pregnancy and postnatal care delivery. IBSWs desire to work with community healthcare providers to provide prenatal care and build relationships before delivery. IBSWs advocated for collaborative cooperation with community healthcare professionals and rural healthcare teams to enable a smooth care flow to and from communities.
Conclusion:
The IBSW program’s client-centered, culturally responsive, compassionate care assisted in meeting the maternal healthcare needs of indigenous women in a hospital context. Birthing families should be provided with elders and spiritual and cultural teachings that support the birthing ceremony throughout the preconception, pregnancy, delivery, postpartum, and postpartum losses. Closer collaboration between IBSWs and healthcare practitioners is advised, as it can aid in identifying healthcare needs and improving timely access to relevant services.
Microgravity Induces Interplay Between Atg8, Tua and Tub Gene Expression in Arabidopsis Thaliana
Authors: Shadrina Ruslana , Yemets Alla , Plokhovska Svitlana , Blume Yaroslav
Published: October 2022

Autophagy plays a direct or indirect roles in plant growth and development, pathogen invasion and immunity. It is involved in the control of cell homeostasis and modulates plant response and adaptation to various abiotic stress stimuli. The formation and motility of autophagosomes require microtubule dynamics. The manner in which autophagy can be induced by microgravity in plants has not been previously studied. Investigating how plants can cope with the absence of gravity is a critical task in space biology, since growing plants as a food source on the space station is in particular demand for the future. The present study demonstrates and confirms that microgravity affects the growth and development of plants. Using different GFP-expressing Arabidopsis thaliana lines (GFP-ATG8 and GFP-MAP4), laser scanning confocal microscopy and gene expression analysis of 6 α-tubulin (tua), 9 β-tubulin (tub) and 9 atg8 genes, we can conclude that main microgravity-induced stress response in plants is observed during the first 6-9 days of the microgravity experiments. It is shown that the morphological changes found in plants are directly related to changes in the organization and dynamics of microtubules. It was found that in root cells microtubules become disorganized after 6 days of growing plants under microgravity conditions, which leads to visible morphological changes in the plants. However, after 9-12 days of the experiment no dramatic disturbances in the orientation and organization of MTs were identified. The results obtained using LysoTracker™ Red and A. thaliana transgenic line (GFP-ATG8a) in both cases showed induction of autophagy and maximum level of autophagosome formation in plant root cells after 6 days of plant growth, and then a gradual decrease of autophagosomes in the same cells after 9 and 12 days under microgravity. The results of transcriptome analysis of tubulin and atg8 genes reveal connection between development of autophagy and functioning of microtubules. In particular, the most pronounced increase of expression in response to microgravity exposure was observed of tua2, tua3, tub2, tub3 and atg8i genes. It should be noted that the main responses to stress were established after 6-9 days of exposure to microgravitation, while after 12 days of the experiment, an adaptive response of plants to microgravity-induced stress was observed.
The findings provide a basis for further studies of cellular mechanisms of autophagy and their interaction with cytoskeletal structures, in particular microtubules, to enhance plant adaptation to microgravity conditions

Published: October 2022

The present work describes the microbial community and gene function in the microbiome associated with Keem, a starter culture used by Jaunsari tribal community of India, for making various traditional alcoholic beverages. For this, Illumina based (MiSeq system) whole metagenome shotgun sequencing approach was followed after extraction of genomic DNA from the starter culture. Initially 22,350,940 sequences with an average base length of 151 bps were obtained comprising a total read of 3,374,991,940 bp. The genomic DNA of human and plant origin was separated during quality control (QC) check and not considered for subsequent downstream analysis. Post QC a total number of 8,665,213 sequences with 1,156,651,659 bp were analysed using MG-RAST which revealed the dominance of bacteria in the microbial community of Keem (95.81% sequences) followed by eukaryota (4.11%), archaea (0.05%) and virus (0.03%). At phylum level, Actinobacteria (81.18%) was the most abundant followed by Firmicutes (10.56%), Proteobacteria (4.00%) and Ascomycota (3.02%). The most predominant genus was Saccharopolyspora (36.31%) followed by Brevibacterium (15.49%), Streptomyces (9.52%), Staphylococcus (875%), Bacillus (4.59%) and Brachybacterium (3.42%). At species level bacterial, fungal and virus population of Keem sample could be categorized into 3347, 57 and 106 species, respectively. Various functional attributes to the sequenced data were assigned using Cluster of Orthologous Groups (COG), Non-supervised Orthologous Groups (NOG), subsystem and KEGG Orthology (KO) annotations.

The test bench demonstrates the principle of operation of the satellite orientation control system with three flywheels and allows for variable adjustment of the parameters of the control laws. The model can be a valuable tool for developing a method for controlling the orientation of satellites of a similar type operating in real-time. The software architecture allows, with the help of "PID" regulation, to adjust the parameters of the orientation control laws for different cases. In the article purpose, all problem of developing a mathematical model for controlling the triaxial orientation of a nanosatellite using three flywheels installed along its main central axes of inertia is considered. To solve the problem, it is necessary to determine the law of change in the vector of the control moment or the direction of control of the movement of the flywheels, which allows the nanosatellite to be transferred from the current angular position to another required angular position. And in article’s conclusions it was found that the total mass of SACS-3DOF is about 2.7 kg, which requires no more than 50% filling of the model with the material of the "PLA" type. This factor has a positive effect on financial expenses and does not limit possible improvements in the future.
Evolution of Forest Policies and Implementation Status of FRA 2006 in India, with special reference to Jharkhand state
Authors: Hembram Shibthakur
Published: October 2022

The Forest Right (FRA) Act, 2006 has been endorsed in 2007 by the Ministry of Tribal Affairs, Government of India. It also has been known as, ‘The Schedule Tribes and Other Tribal Forest Dwellers Act, 2006’. The majority of the tribal peoples are living in the forest and they are landless and deprived. Their deprived condition was identified by the outliner of the Indian Constitution; thus they have been given special protection by recognizing them as ‘Scheduled Tribes’ through the Constitution (Scheduled Tribes) Order, 1950. Incidentally, India has the highest tribal population in the world. During the Colonial period, the vast tract of forest land was controlled by the British Government. That was the reason for the suffering of tribal people in every way, especially in respect of their means of livelihood. In the year 1864-65 first time forest act was legislated. The enactment of the 1878 act provided the Colonial government enormous power to declare any forest land as ‘government land’. After that several acts were enacted like the Madras Presidency Act 1882, National Forest Policy (NFP) 1894, and Land Acquisition Act of 1894. This act was in the favour of forest dwellers and tribal people in India. Because it has the power to forcibly acquire any land for the interest of ‘public purpose’. This act makes displaced forest dwellers on the pretext of development projects over the country. Finally, the Forest Right Act 2006 has been enacted to provide for those who are primarily residing in the forest or forest land or those who depend on it for acquiring their means of livelihood. The law recognizes three types of rights: land rights, the right to use and collect forest products, and the right to protect and conserve the forest. Though, the conservationist and forestry administrators opposed the act as it could damage the forest as well as wildlife. Here Jharkhand state has been considered as a case study to examine the implementation status of FRA and its post-implementation effect on forest cover. To achieve this objective basic statistics and univariate and multivariate regression analysis has been used. From that study it has been found that Jharkhand ranked behind its neighbouring states, there has been scope for implementation of FRA furthermore in number. Forest cover area has increased in the post-implementation period.
Contemporary oceanic radiocarbon response to ocean circulation changes
Authors: Byju Pookkandy , Graven Heather , Martin Adrian
Published: October 2022

Radiocarbon (14C) is a valuable tracer of ocean circulation, owing to its natural decay over thousands of years and to its perturbation by nuclear weapons testing in the 1950s and 1960s. Previous studies have used 14C to evaluate models or to investigate past climate change. However, the relationship between ocean 14C and ocean circulation changes over the past few decades has not been explored. Here we use an Ocean-Sea-ice model (NEMO) forced with transient or fixed atmospheric reanalysis (JRA-55-do) and atmospheric 14C and CO2 boundary conditions to investigate the effect of ocean circulation trends and variability on 14C. We find that 14C/C (∆14C) variability is generally anti-correlated with potential density variability. The areas where the largest variability occurs varies by depth: in upwelling regions at the surface, at the edges of the subtropical gyres at 300m depth, and in Antarctic Intermediate Water and North Atlantic Deep Water at 1000m depth. We find that trends in the Atlantic Meridional Overturning Circulation may influence trends in ∆14C in the North Atlantic. In the high-variability regions the simulated variations are larger than typical ocean ∆14C measurement uncertainty of 2–5‰ suggesting that ∆14C data could provide a useful tracer of circulation changes.
Access-Adaptive Priority Search Tree
Authors: Massa Haley , Uhlmann Jeffrey
Published: October 2022

In this paper we introduce the notion of explicit worst-case bounded adaptive algorithms for applications with fixed process-completion requirements. Such applications demand that a process be guaranteed to complete within an established time interval while adaptively reducing computational overhead during that interval, e.g., so as to reduce total energy usage. Our principal contribution is the access-adaptive priority search tree (AAPST), which can provide efficient distribution-sensitive performance comparable to the splay tree, but do so within strict – and O(logn) optimal – worst-case per-query bounds. More specifically, while the splay tree is conjectured to offer optimal adaptive amortized query complexity, it may require O(n) for individual queries, whereas the AAPST offers competitive distribution-sensitive performance with strict O(logn) time complexity. This makes the AAPST more suitable for certain interactive (e.g., online and real-time) applications such as space system modules with reliability constraints involving rigid process- completion time intervals with secondary energy-minimization incentives.

Published: October 2022

On July 29–30, 2022, a disastrous rainfall-induced landslide occurred at Tupul in Tamenglong district Manipur India. The fast-moving debris material from the landslide wiped out the under-construction Tupul railway station, a part of the Jiribam - Imphal rail project, blocking the flow of the Ijai River. More than 54 lives were lost which included the Territorial Army soldiers, railway workers, and a few local village commuters. Upon the analysis of rainfall data acquired from news reports, information about the past earthquake, lithological characteristics, and presence of faults zones revealed that the landslide resulted due to the presence of a fault and weak rock formation and triggered due to excessive rainfall in the region. Using high-resolution satellite images, the material from the landslide blocked the Ijai river creating a temporary lake creating a threat to downstream villages. This landslide was considered a tragic incident in the history of the Manipur state due to the area affected and the causality caused. Moreover, after the landslide, the safety and sustainability of the proposed railway project need to be studied in detail.
Substance (mis)use among refugees as a matter of social ecology: insights into a multi-site rapid assessment in Germany
Authors: Hertner Laura , Stylianopoulos Panagiotis , Heinz Andreas , Kluge Ulrike , Schäfer Ingo , Penka Simone
Published: October 2022

Background
Previous research concluded that substance (mis)use is increasing among forcibly displaced populations. Nevertheless, little research has been conducted within a social ecological framework aimed at identifying and understanding the factors impacting substance (mis)use embedded in the post-migration context in high-income countries.
Methods
Rapid assessments (RAs), including 108 semi-structured interviews and 10 focus group discussions with key persons from different professional, volunteering and personal backgrounds, were carried out in German urban and rural areas. The RA approach of interviewing both, key persons and refugees, regarding substance (mis)use by refugee communities in Germany and not solely substance (mis)using refugees allowed us to gather multi-perspective knowledge on this sensitive topic. Data were analyzed, aiming at identifying determinants of substance (mis)use embedded in the post-migration context of refugees and at comprehensive and in-depth examination.
Results
As one main result, the commonly reproduced link between refugees’ countries of origin and their substance (mis)use was found to be mediated by the prospects and opportunities refugees have in receiving countries (e.g., work permit). Further determinants are related to living conditions in German refugee shelters and social relations with peers and families. The impact of refugees’ living conditions can be summarized as potentially increasing substance availability and distress, whereas the absence of family likewise produces a loss of control by family and traditional authorities and responsibility, allowing for substance (mis)use. Peers’ impact on substance (mis)use reflects a search for a sense of belonging.
Conclusions
Given that substance (mis)using refugees have limited to no control over the substance (mis)use triggering factors identified, common treatment and prevention approaches are challenged. Furthermore, we strongly recommend aiming for a holistic comprehension of refugees’ substance (mis)use by expanding the focus beyond individuals to the social ecological context in any attempt, including prevention, treatment, research and policy.

The leading cause of myocardial ischemia in case of coronary atherosclerosis and coronary vasospasm combination in one patient is difficult to establish. However, it is important to know for optimal treatment strategy: choosing between beta-blockers and calcium channel blockers as a preferred treatment, need for percutaneous coronary intervention. We present a case of a 56-yearold patient who was admitted with acute coronary syndrome without ST-segment elevation, low Killip class, and low GRACE score. Stress echocardiography revealed inducible transmural myocardial ischemia (regional wall motion abnormalities and ST segment elevation on the  ECG) accompanied by polymorphic ventricular tachycardia. The coronary angiography showed single-vessel moderate stenosis in the left anterior descending artery. There were no changes in comparison with previous angiography. The patient was considered to have vasospastic angina. A probable mechanism is coronary artery spasm at the site of the atherosclerotic plaque. The article is discussed the difficulties in diagnosing vasospastic angina, especially in the presence of borderline stenosis in the coronary artery. We reviewed similar cases and discussed the difficulties of a vasospastic angina diagnosis especially in the presence of moderate coronary artery stenosis, the role of the provocative tests, and the pharmacological management. Demonstrating, discussing and analyzing cases of patients with a combined mechanism of myocardial ischemia is substantiated for further improving their diagnosis and treatment.
Сlinical and allergological characteristics of chronic inflammatory diseases of the nose in patients with severe bronchial asthma receiving immunobiological therapy in the Sverdlovsk region
Authors: Kiseleva D. V. , Beltyukov E. K. , Naumova V. V.
Published: October 2022

Introduction. Allergic rhinitis, chronic rhinosinusitis (with/without polyps) are chronic inflammatory diseases of the nose and often accompany asthma, aggravating its severity.

Aim of the study. Тo determine the phenotypes, spectrum of sensitization and severity of chronic inflammatory diseases of the nose in patients with severe bronchial asthma receiving immunobiological therapy in the Sverdlovsk region.

Materials and methods. The territorial register of adult patients with severe bronchial asthma (n = 85) who received immunobiological therapy in the Sverdlovsk region in October 2021 was analyzed. When diagnosing chronic inflammatory diseases of the nose, an examination by an otorhinolaryngologist and computed tomography of the paranasal sinuses were performed; were determined: the  absolute number of  blood eosinophils, specific IgE to inhaled allergens, including the FadiatopTM method; skin tests were performed; assessment of the severity of nasal symptoms was determined using the SNOT-22, VAS.

Results. Chronic inflammatory diseases of the nose were reported in 89.4% of patients. Allergic rhinitis occurred in 54.1% of cases (n = 46). 54.3% (n = 25) were dominated by patients with a moderate course; severe course was observed in 28.3% of cases (n = 13). Allergic rhinitis in 92.3% of cases (n = 36) was accompanied by allergic asthma and in 71.4% (n = 10) – mixed. Sensitization to household allergens was more common, from seasonal allergens to tree pollen. Phadiatop was positive in all patients with allergic rhinitis and negative in patients with chronic rhinosinusitis with/without nasal polyps. Patients with chronic rhinosinusitis occurred in 35.3% of cases (n=30); nasal polyps were in 23.5% (n = 20). The highest rates of blood eosinophilia were in patients with concomitant chronic rhinosinusitis with nasal polyps – 920 cells/µl. This phenotype in 95% of cases was accompanied by non-allergic (eosinophilic) asthma.

Conclusion. Severe bronchial asthma is almost always accompanied by chronic inflammatory diseases of the nose. Phadiatop shows its high informativeness in determining the phenotype of allergic rhinitis.
Double broncholytic combination of umeclidnium/ vilanterol in COPD therapy: issues of efficacy and safety

Inhaled bronchodilators are the basis of pharmacological therapy of chronic obstructive pulmonary disease. Bronchodilation can be reached in two different ways: by stimulation of β2 -adrenoreceptors and inhibition of M3-cholinoreceptors. Combined long acting bronchodilators show additional effect on lung function and clinical outcomes of the disease. This article covers the issues of efficacy and safety of different combined bronchodilators. Chronic obstructive pulmonary disease (COPD) is a disease characterized by the limitation of air flow velocity, which is reversible incompletely. The restriction of air flow velocity is usually progressive and is associated with inflammatory response of the lungs to pathogenic particles or gases, with tobacco smoking being the main cause. COPD leads to a number of significant systemic effects that can worsen the course of the disease. It is important that COPD can be prevented and treated. The Global Strategy for the Diagnosis, Treatment and Prevention of Chronic Obstructive Pulmonary Disease  (GOLD) considers long-acting inhaled bronchodilators as the  basis for  long-term maintenance therapy of  chronic obstructive pulmonary disease. GOLD recommends the  use of  both long-acting anticholinergic drugs  (LAMA) and long-acting β2-agonists (LABA) in all categories of patients, including as the first line in people with severe symptoms and low risk of exacerbations. bronchodilators reduce the severity of shortness of breath and other symptoms of the disease, and also increase exercise tolerance. The individual components have different application points: LAMA inhibit the effect of acetylcholine mainly on M1- and M3-muscarinic receptors, LABA stimulate β2-adrenergic receptors, increasing the content of intracellular cAMP and causing bronchodilation. Both classes of drugs potentiate each other’s activity, increasing the relaxing effect on the smooth muscles of the bronchi.

Published: October 2022

Mucoactive drugs are commonly used in  the treatment of  respiratory diseases such as chronic bronchitis  (CB) or chronic obstructive pulmonary disease (COPD), in which hypercrinia is one of the main clinical features. Erdostein is one of the most commonly used mucoactive agents for the treatment of respiratory diseases. Erdostein is a drug approved for the treatment of acute and chronic lung diseases, originally developed as a mucolytic agent. It belongs to a family of thiol-based drugs, which, in  addition to mucolytic action, also have antioxidant and anti-inflammatory properties and exhibit antibacterial activity against various types of bacteria. Erdosteine is a prodrug that is converted to the active metabolite M1 (MET 1), which has mucolytic properties. Experimental studies have confirmed that erdosteine prevents or reduces damage to lung tissue caused by oxidative stress, and also regulates the production of reactive oxygen species. The RESTORE study, the only study that examined the effect of a thiol-based drug in chronic obstructive pulmonary disease (COPD) with frequent exacerbations, confirmed that erdosteine significantly reduces the risk of acute exacerbations of COPD, reduces their duration, and also reduces the risk of hospitalization for COPD. The preventive effect of erdosteine against exacerbations of COPD was not affected by the presence or absence of inhaled corticosteroids (ICS) or the number of eosinophils in the blood. Recent studies on the pharmacological effects of erdosteine have shown promising results, which paves the way for the use of additional pharmacological effects of erdosteine as promising therapeutic strategies in patients with pulmonary diseases.

Authors: Yuan Dongbing , Zhang Yue
Published: October 2022

In the power line communication network, the electrical node switch connected to the Power Line Communication network will affect the impedance, noise and signal attenuation of the network. The connection change between the network nodes will lead to the change of the topology structure. This paper proposes a new type of automatic modulation pattern recognition system assisted by blind channel recognition based on a convolutional neural network, which is composed of two convolutional neural networks with different architectures, and successfully improves the recognition accuracy of the traditional automatic modulation pattern recognition system. The Signal to Noise Ratio recognition rate of the proposed blind channel recognition assisted Adaptive Multi-Rate system is as high as 99 %, which is more than 5 % higher than that of other comparison methods. After several iterations, the accuracy and loss function of the model studied in this paper are still at a stable level. The intelligent recognition technology of blind signals proposed in this paper can effectively improve the interference problem of communication signals in power system and has a promotion effect in other communication systems, which can achieve higher technical application value.
Can guava (Psidium guajava) leaf extracts develop an indigenous, simplified tool for a semi-quantitative assessment of iron in groundwater?
Authors: Rahman Sabuktagin , Saha Nobonita , Sarwar Sneha , Shamim Abu Ahmed , Shaheen Nazma
Published: October 2022

Iron present in the drinking groundwater is attributed to the low burden of iron deficiency (ID) in Bangladesh. The supplemental anemia prevention strategies involving iron need a cautious approach due to the excess load of iron and the side effects. The present pilot study examined the potential of the guava leaf extracts to use as a natural reagent for the assessment of iron in groundwater. Eighteen households with the drinking source of groundwater were randomly selected. Guava leaves were crushed and the shreds of the leaves were mixed with the water sample. Changes of water color were photographed. Five groups were identified – ‘whitish’, ‘shades of pink’, ‘shades of purple’, ‘light black’ and the ‘frank black’. The iron concentration was measured by a test kit device. Each color group was assigned a number on the ordinal scale 1–5. Statistical correlation and agreements were performed between the methods. The positive correlation (Kendall's tau b: 0.89, p < 0.000) and the agreements (Kappa: 0.77, p < 0.000; rho_c: 0.73, p < 0.000) were observed. Guava leaf extracts may standardize an indigenous tool for a semi-quantitative measurement of groundwater iron content. Validation of the tool thus may aid in the design and evaluation of the iron supplementation and fortification programs.
Analytic network process for local scour formula ranking with parametric sensitivity analysis and soil class clustering
Authors: Annad Mohamed , Lefkir Abdelouahab
Published: October 2022

Prediction of scour depth around bridge piers during flood events has been and continues to be regarded as a paramount concern for researchers of local scour, and many empirical formulas have been proposed. Because of the multiplicity and variability of these formulas, it remains extremely delicate to choose the correct formula among the many available. This study aims to develop a new framework to compare the different formulas currently used for the evaluation of local scour. For this purpose, 18 distinctly different formulas are selected and then evaluated using a large set of field-measured scour data. The rating is pronounced along three main streambed granulometric distributions. The validation process is performed using the Analytical Network Process approach (ANP), in which the already available conventional weights are re-evaluated and updated using various analyses, notably in terms of statistics, sensitivity, and correlation. The validation and comparison results of these 18 scour formulas reveal that the efficiency of a given particular formula depends on the type of stream soil studied. Furthermore, the scour formulas that include parameters having a geometrical dimension provide better performances.
2022: state in transitional era in transitional area
Authors: Kostiuk Tetiana
Published: October 2022

Throughout the history of mankind, the most difficult task has always been and remains the maintenance of society and social life in an orderly, balanced and dynamic state of optimal viability. The depressing regularity of social cataclysms, wars, crises, and local conflicts convincingly testifies to the extreme complexity of this task. Such complexity, however, does not negate the need and importance of scientific support for the analysis of the causes of specific bifurcation points in the societies’ evolution and the development of new theoretical and empirical approaches to the study of their consequences, renaissances and transformations. The purpose of this article is to enrich (perhaps deepen) the modern vision of the categories of spatial and temporal transit of states in the context of a full-scale war in the heart of Europe by means of a detailed depiction of potential vectors of its direction within the framework of carefully chosen situational analytical optics.The methodological toolkit of this study is shaped by a synergistic approach, which allows considering transition in its development in space and time depending on attractors. The principle of retrospective analysis and extrapolation makes it possible to draw parallels to confirm the predictions and avoid the gap between theory and reality.The research highlights that in conditions of russian aggression against Ukraine the concept of transition has a clearly expressed spatial and temporal determinism and affects a number of spheres that are undergoing the greatest transformations. Within the analysis of the reformatting of specific spheres, which is now based on the nature of responding to the extreme challenge of time, this study offers a binary overview of supranational (regional) and national trends. Reconstructing the post-war agenda, it was found that security, military, humanitarian and migration policies are undergoing the biggest changes, as well as their consequences for individual states and the EU as a whole, This article may contain forecasts and provisions that can cause discussions, but taking into account that the war is not stopped yet and the variability of the development of events, it allows to go beyond the traditional discourse of transit, provoking the exit of scientific research to a qualitatively new level of theoretical reflection of the emanation of nowadays transformational challenges.
Transsociality as uncertainty or incertitude of the human condition
Authors: Liakh Vitalii , Lukashenko Maryna
Published: October 2022

Uncertainty, dynamism of transformations, liquid and incertitude are the leading features of the present age, through which time, society, and human situation are increasingly defined. This work examines the interrelationships between human position and social change in traditional, modern, and postmodern societies. The “social – personal” system is considered in the context of changes in the understanding of the humanistic attitude. Thus, the humanism of pre-modern society is particular, i.e. limited to belonging to a certain group, whose virtues are nurtured and formed through education. The sociality of traditional society is natural, rooted in the idea of the divine, and it aspires to the transcendent. In return, modern sociality is constructed around an exclusive humanism that excludes the transcendent, for which only the human matters are important. The sociality of postmodern society is correlated with the spread of antihumanism and transhumanism, both of which overcome the boundaries of the abstract idea of the universal human subject in different ways. One of them is focusing on the phenomena beyond the human nature, and the other one is oriented toward its improvement. The goal of the second approach is to use new technologies to overcome death, aging, and suffering which also applies to all living things beyond humanity.In crisis periods of changes in the type of sociality, uncertainty and insecurity increase, which is analyzed in two paradigms. A resource-oriented view of the history of mankind shows the modern improvement of the human condition, focusing on the further development of the state’s human capital (plasticity, adaptability, stress resilience, creativity, cognitive and emotional abilities of individuals). The defined position of consideration differs from the consideration of a person in pre-modern and modern societies, when a person was a physical resource and social capital. A problem-oriented approach analyzes signs of crises and dangers, foresees possible options for the development of events, and warns of possible disasters in order to be protected from them. Thus, the analysis of the crisis of sociality indicates the emergence of its new multiple forms, which are formed both by dispersal and by going beyond the boundaries of human communities, which allows describing new forms of sociality through the concept of transsociality.

Background

Virtual reality (VR) devices are increasingly used in health care settings. The use among patients has the potential to unintentionally transmit pathogens between patients and hospital staff. No standard operating procedure for disinfection exists to ensure safe use between patients.

Objective

This study aims to determine the efficacy of disinfectants on VR devices in order to ensure safe use in health care settings.

Methods

Three types of bacteria were inoculated onto porous and nonporous surfaces of 2 VR devices: the Meta Oculus Quest and Meta Oculus Quest 2. Disinfection was performed using either isopropyl alcohol or alcohol-free quaternary ammonium wipes. A quantitative culture was used to assess the adequacy of disinfection. A survey was separately sent out to VR device technicians at other pediatric health care institutes to compare the methods of disinfection and how they were established.

Results

Both products achieved adequate disinfection of the treated surfaces; however, a greater log-kill was achieved on nonporous surfaces than on the porous surfaces. Alcohol performed better than quaternary ammonium on porous surfaces. The survey respondents reported a wide variability in disinfection processes with only 1 person reporting an established standard operating procedure.

Conclusions

Disinfection can be achieved through the use of either isopropyl alcohol or quaternary ammonium products. Porous surfaces showed lesser log-kill rates than the nonporous surfaces, indicating that the use of an added barrier may be of benefit and should be a point of future research. Given the variability in the disinfection process across health care systems, a standard operating procedure is proposed.

Published: October 2022

BACKGROUND

Workplace concussions can have a significant impact on workers. The impact of concussion symptoms combined with challenges associated with clinical environments that are loud, bright and busy, create barriers to conducting effective in-person assessments. While the opportunity for remote care in rural communities has long been recognized, the COVID-19 pandemic has catalyzed the transition to virtual assessments and care into the mainstream. With this rapid shift, many clinicians have been completing remote assessments. However, the approaches and measures used in these assessments have not yet been standardized. Furthermore, the psychometric properties of the assessments when completed remotely using videoconference have not yet been documented.

OBJECTIVE

Through this mixed-methods study, we aim: 1) To identify which concussion assessment measures clinicians are currently using in-person and are most relevant to five physical domains: neurological examination (cranial nerve, coordination, motor, sensory), cervical spine, vestibular, oculomotor, and effort assessment; 2) To document the psychometric properties of the measures identified; 3) To identify measures that appear feasible in a virtual context; and 4) To identify practical and technical barriers/challenges, facilitators and benefits to conducting or engaging in virtual concussion assessments.

METHODS

This study will follow a sequential mixed methods design using a survey and Delphi approach, working groups with expert clinicians, and focus groups with experienced clinicians and people living with concussions. Our target sample sizes are 50 clinicians for the Delphi surveys, 4 clinician-participants for the working group, and 5-7 participants for each focus group (roughly 6-10 total groups being planned with at least two groups consisting of people living with concussions). The results from this study will inform the decision regarding which measures to include in a virtual assessment toolkit, to be tested in a future planned prospective evaluation study.

RESULTS

The study is expected to be completed by December 2022.

CONCLUSIONS

This mixed-methods study will document the clinical measures that are currently used in-person and identify those that are most relevant to assessing the physical domains impacted by concussions. Potential feasibility of using these measures in a virtual context will be explored.

Three arms Schiff base unit based on melamine moiety was synthesized and introduced to polyvinyl chloride (PVC) to produce a modified PVC polymer. The polymer composite of new modified PVC polymer was blended with micro copper oxide as a reflecting mirror of UV light to enhance the photostability of PVC. Three different concentrations of micro copper oxide (0.01–0.03 wt.%) were mixed with the modified PVC and cast as a thin film. The photostability test has shown high resistance to photodegradation upon exposure to UV light. In this work, different approaches were applied to examining doped modified PVC's thin film efficiency against photodegradation after exposure to UV light for 300 h in an ambient atmosphere. The exhibited studies, such as infrared spectroscopy and weight loss percentage, have demonstrated the improvement of photophysical properties for modified PVC and blended modified films in comparison to blank PVC polymeric films. These outcomes are so interesting as they could contribute to reducing the consumption of PVC around the world hence its waste causing huge environmental problems for the marine ecosystem.
Financial Instruments for Attracting Investments in the Real Estate Market

Subject of the study: REIT (Real Estate Investment Trust) as equity investment instrument issued by management companies that are involved in the purchase, maintenance and construction of new real estate, and can also buy mortgage-backed securities from banks.The object of the study is the analysis (Real Estate Investment Trust) real estate market in China.The purpose of the work is to draw a conclusion about the attractiveness of investment in real estate in modern conditions relative to other tools and to identify the development prospects of REITs in ChinaResearch methods: descriptive-analytical, comparative-comparative, statistical, formant, contextual analysis methods.This thesis finds that equity REITs are still very immature and are not widely accepted by mass investors in China. The thesis puts forward three suggestions for apartment REITs in China: to streamline the REIT structure and avoid excessive complexity and opacity; to promote information transparency and regulated disclosure mechanism; to encourage and protect equity REIT investors by constraining REITs from taking on too much debt. Finally, the thesis concludes that REITs, as shown by US experience, should be regarded as a great opportunity to cultivate Chinese investors’ confidence in the stock market with its very simple and plain-vanilla structure. With the Chinese government’s strong ambition to increase housing affordability and to deleverage the economy, we foresee continuous legislative breakthroughs and more systematic improvements in the REIT field.Novelty elements: the current apartment operators are using REITs as debt-financing channels instead of real equity financing. As a result, the leverage level of the real estate sector may not really be decreased at all, but rather increased. With regard to this, the overall leverage level of the emerging apartment REIT companies should be a key factor that must be monitored to embody REIT as an equity investment vehicle.This work is dedicated to solve a number of difficulties in relevant fields of economy.

Psoriasis is a chronic, non-communicable disease for which there is no cure. It can involve skin, nails and joints and affected individuals are more susceptible to having comorbidities. The worldwide prevalence is approximately 2%, having a great impact on quality of life. Although the etiology is uncertain, the disease is believed to result from a complex interaction between genetics, environment and the immune system. The characteristic lesions of psoriasis are silvery-white scaly erythematous plaques, the most common subtype being psoriasis vulgaris. Because there is an environmental component involved, there are some triggers that can trigger the disease or exacerbate it, among them other infections, such as Covid-19, which was responsible for the pandemic that started in December 2019. The objective of this study is to make an analysis of documented cases of exacerbation of psoriasis by Covid-19. For this purpose, a search was carried out in Pubmed, LILACS, Science Direct, Scielo and Cochrane Library databases. Studies cite as a justification for this event, the emotional stress caused by social isolation, fear after diagnosis and the pathophysiology of Covid-19 itself, causing a greater inflammatory state in the affected individual.

Authors: Undalkar Rushikesh
Published: October 2022

Abstract: Industrial wastewater contains organic impurities such as nitrogen compounds and many more. There is a limit to each compound in wastewater before discharging it into the ecosystem. It is maximum 2000-4000 g N/m3. It also depends upon different countries' environmental conservation laws. As nitrogen is harmful for aquatic life in low concentrations as well, it is needed to be treated before discharging and also before reuse in other applications. the removal of ammonia can be accomplished by steam stripping as well as by air stripping i.e. absorption and desorption. the conventional method of removal of ammonia is packed tower which has many issues in operation. Presently there are many advancements in removal of ammonia and research are going on in this paper we will discuss development in ammonia stripping and application with different sources of waste water from different industries.

Abstract: In older citizens, Osteoarthritis (OA) in the knees is a frequent cause of restriction in movement and significant decline in their overall wellbeing. Early OA evaluation and treatment can prevent further progression. The accurate evaluation of a visual examination by a doctor is subject to different interpretations and heavily reliant on the degree of expertise that the doctor has. In this study, we use a method called deep learning (VGG16) to determine the severity of knee pain immediately. Simple Xray pictures collected from Kaggle are evaluated and divided into five grades. This model successfully reached a mean precision of 0.858 and a recall of 92.2 percent for knee osteoarthritis grading.
