Published: June 2023

This study aims to identify students' satisfaction with online learning and their expectations of blended learning in the post-pandemic era in a senior high public school in North Bali, Indonesia. The research employed an explanatory sequential mixed-method design using questionnaires and interviews, to gather data from 179 grade 12 senior high school students. The questionnaire and interview guide were validated with face, content, empirical validity, and reliability. The interview session involved 5 students with high satisfaction scores and 5 students with low satisfaction scores from the result of the questionnaire. The results showed that students had a mode score of 4, indicating students feel satisfied with online learning during COVID-19. Based on the four factors, the result of students’ satisfaction in online learning such as the teacher factor having neutral scores, the interaction factor having satisfied scores, the technology factor having satisfied scores, and the course management factor having satisfied scores. The interview session shows that students expressed their expectations for direct interaction with teachers and classmates and had expectations for factors, such as teaching methods, ease of materials, direct communication with teachers, interaction with classmates, technology use, and variety in learning resources. This research provides insights for teachers to improve student satisfaction with online learning and blended learning practices.
MAXIM GORKY’S PARTICIPATION IN CHILDREN’S LITERARY PROJECTS
Authors:   A. M. Gorky Institute of World Literature of the Russian Academy of Sciences, Kudrina Elena
Published: June 2023

Maxim Gorky corresponded with children all his life, carried out “social orders” for a fairy tale and supported children’s publishing projects: Shkola shalunov (“School of naughty”) (1909), Interesnye neznakomtsy (“Interesting strangers”) (Deti i voyna) (1919), Kem khotyat byt’ nashi deti (“Who our children want to be”) (1929), My zhivem v “Gigante” (“We live in ‘Gigante’”) (1930). In 1934, Gorky approved a unique literary project initiated by children — Baza Kurnosykh (“Snub-nosed base”). The article cites a previously unpublished letter from the children, which they sent to Gorky along with their book. The creativity of the literary circle, which was headed by the poet Ivan Molchanov-Sibirsky, received All-Union recognition. The authors were invited to the First Congress of Soviet Writers, personally communicated with Gorky. Impressions from a trip to Moscow made up the second book Baza Kurnosykh v Gostyakh u Gor’kogo (“The snub-nosed base visiting Gorky”) (1936). The article examines the evolution of Maxim Gorky’s attitude to children’s writing: from the early stage of enthusiasm for children’s creativity to the late skeptical view of children’s graphomania. Gorky critically evaluated the works of young authors, which glorified the USSR, and attached great importance to children’s books as a means of education.
‘VOICELESSNESS IS FOLLOWED BY DEAFNESS’ TO THE TEXT AND... IT IS OVERCOME IN SCHOOL CREATIVE ESSAYS (DWELLING ON MARIYA RYBNIKOVA’S ARTICLE OT MALEN’KOGO PISATELYA — K BOL’SHOMU CHITATELYU (“FROM THE LITTLE WRITER — TO THE BIG READER”))
Authors:   Moscow City University, Romanicheva Elena
Published: June 2023

The author turns to an article by Mariya Rybnikova Ot malen’kogo pisatelya — k bol’shomu chitatelyu (“From the little writer — to the big reader”). Analysing the article and simultaneously turning to other works, the author considers Rybnikova’s attempt to integrate class work and extracurricular activities by concentrating on the development of pupils’ creative skills, amongst other things through teaching how to write a creative essay. Looking at pupils’ literary creative activities form the ‘teacher’s’ point of view, Rybnikova claims that if a little reader has never tried to write a text, then ‘the voicelessness is followed by deafness’ to the word, to the work of fiction, so writing your own text should precede reading. The methodologist proposes that the teaching of creative essays should be based on an understanding of the situation of the pupil, who is just beginning to enter the world of literature, and on his life observations, which he records in his text. Describing her own creative writing class, she demonstrates how this can be done in any class with various children. Teaching creativity, as shown by the methodologist in further articles, goes on follows a certain procedure: development of the ability to see and to observe, the choice of a precise word to record one’s thoughts and feelings, the enrichment of one’s vocabulary (which includes turning to a classical text while analyzing it), outlining of the material.
PAPER CRAFTS IN SOVIET CHILDREN’S MAGAZINES AND CALENDARS: ON THE MATERIAL OF DETSKYI KALENDAR (“CHILDREN’S CALENDAR”) AND ZVEZDOCHKA (“STAR”)
Authors:   The Herzen State Pedagogical University of Russia, Korvackaya Elena
Published: June 2023

The subject of this study is paper handicrafts, which were offered as supplements to Soviet magazines and calendars for children. They are considered in the article as a phenomenon of Soviet mass culture in the context of the development of children’s creativity and play activities. Attention is paid to the constructors in the periodicals of the 1920s-1960s (“Murzilka”, “Det- skiy Kalendar” and “Zvezdochka”); their existence is linked to the ideas of personality building of a Soviet man, his general cultural development and socialization (including initiation to reading). In addition to forming the foundations of artistic and technical creativity and work culture, paper handicrafts solved the problem of a shortage of consumer goods, in particular toys. The annual publication Detskyi Kalendar (“Children’s calendar”) for primary and secondary school age which was edited by methodologist Elizaveta Grozdova in the 1940s-1950s is discussed in detail. It was a part of a Soviet child’s reading circle and could offer its readers a variety of self-made paper models and designs. The publication Detskyi Kalendar (“Children’s calendar”) reflects the characteristic features of the development of artistic construction, namely the transition from creating a toy using an already existing blueprint, by analogy with self-made models of the pre-revolutionary period, to making a blueprint or one’s own model.

CdS Covered with Ga-P Electron Exchange Membrane for Efficient Photocatalytic Hydrogen Prodection
Authors: Wang Zejin , Zhang Linqing , Jin Zhiliang
Published: June 2023

Abstract: CdS is one of the best semiconductor photocatalysts. However, photocorrosion will occur when CdS takes part in the photocatalytic system. The general solution is to add sacrificial reagents to inhibit this phenomenon. Even so, it can not maintain the stability of CdS. In order to improve the stability and efficiency of CdS in pure water, Ga-P electron exchange membrane was designed to modify its surface. Under radiation of visible light, a significant increase can be observed in hydrogen production activity. In the absence of Pt as electron transfer agent, the modification of Ga-P realizes decomposition of pure water from zero to one. At the same time, the hydrogen production rate is increased about 5 times with Pt and catalytic life is greatly extended. Through proof of controlled experiment, Ga-P electron exchange membrane can not only prolong the lifetime of photogenerated electrons, but also change the direction of electrons. The formation of a protective membrane makes composite photocatalyst improve the stability and enhance the photocatalytic activity. Based on the analysis of TEM, fluorescence lifetime, UV-Vis diffuse reflection and photocurrent response, the mechanism is analyzed from atomic radius, nuclear orbit and energy level. For homogeneous electronic band structure and XPS analysis, we determined that the binary catalyst formed an S-scheme heterojunction. The work provides a potential way to design a more efficient and stable composite photocatalyst in the future. And contributed to the development of S-scheme heterojunctions.
Exploring Ways of HIV Transmission in Correctional Facilities in the Democratic Republic of the Congo
Authors: Tumba T.D , Ukwandu D.C
Published: June 2023

The Democratic Republic of Congo (DRC) is one of the few African countries where human immunodeficiency virus (HIV) transmission is still a silent issue. In the context of the DRC, the purpose of this paper was to investigate how HIV is transmitted among inmates within Congolese correctional facilities. It focuses on the ways certain Congolese correctional services‘ cultures facilitate the spread of HIV. The paper argues that incarceration settings allow for the importation of pre-incarceration lifestyles and risky behaviours into prisons; hence increasing the risk of HIV/AIDS (acquired immunodeficiency syndrome) transmission among convicts. Methodologically, the paper followed a qualitative approach based mainly on secondary data. A content analysis was used to analyse the data. The findings of the study indicated that prisoners‘ pre-incarceration lifestyle supplemented by prison culture and settings engendered HIV high-risk behaviour among inmates in Congo‘s prisons. In addition, the paper appealed for the government to pay attention to prison cultures generated by the interaction between prison environments and a quest for a sense of psychological wellbeing inside correctional facilities.
Dynamics of Total Quality Management to Improve Student Outcomes in Private TVET Colleges in Gauteng, South Africa
Authors: Mzuvukile Mtotywa Matolwandile , Odebiyi Iyabode
Published: June 2023

Technical Vocational Education and Training (TVET) colleges can provide students with the knowledge and skills they need for future jobs. The study aimed to determine the mediation effects of total quality management (TQM) dimensions on employee performance and student learning outcomes. The study employed a cross-sectional descriptive quantitative design, where the research collected 349 responses from a pool of colleges in Gauteng, South Africa. The results show that training has the largest mediation effect size, with 55.1% of employee performance’s effect (total effect) on learning outcomes mediated by training. Knowledge and process management (34.8%) and customer focus (34.6%) also had a high mediation effect; however, no mediation effect was found with employee participation. This study helps the management of TVET colleges identify priority areas when they engage in the journey of TQM. The theoretical implication is that even though all the dimensions of TQM are critical in the organisation, they can be prioritised based on context and the environment where the implementation is taking place.

Authors: Mettanadi Andre Hartawan , Prabowo Aditya Rio , Kusharjanta Bambang , Muttaqie Teguh , Laksono Fajar Budi , Nubli Haris
Published: June 2023

Safety Impact resistance is defined as the ability of a material to absorb impact energy through controlled failure mechanism. The greater the energy absorption by the crash safety structure, the greater the safety in preventing deformation of the main structure due to impact. In this study, numerical validation, mesh convergence studies and multiple load case studies were performed to investigate crash resistance under axial loading. Numerical validation results show that the similarity between this study and the reference reaches 95%. A deviation of 5% occurs due to different input material properties. The results show that the concave hexagons as filling elements have greater energy absorption capacity than conventional hollow tubes, and the more concave hexagonal structures, the better the energy absorption. Oblique compression was performed in this study and as a result the sample has good impact resistance at low angles and no effect at high angles like 20°.

Authors: Patel Paresh , Joshi Digesh , Makawana Rinkesh
Published: June 2023

Structural strengthening is vital to improve the load-carrying capacity partially or severely damaged Reinforced Concrete (RC) elements. Fiber Reinforced Polymers (FRPs) are widely used for strengthening purposes. In this study, use of Stainless-Steel Wire Mesh (SSWM) is explored, as FRPs are having limitations like high cost, less fire resistance, and brittle behavior. The experimental studies are conducted to evaluate the mechanical properties of the SSWM, to explore its feasibility as a strengthening material. Three different variants of SSWM i.e., 30×32, 40×32 and 50×34 is considered for the study. SSWM used in present study is a woven mesh made from stainless-steel wires manufactured in India. Important mechanical properties such as tensile strength and bond strength with concrete surface is experimentally evaluated in this study. Response of test specimens are evaluated with respect to ultimate load carrying capacity, corresponding deformations, rupture strain, crack formation and failure propagation. SSWM exhibits a tensile strength of 600-1000 MPa which is comparable to tensile strength of various types of fibers used for strengthening. Based on experimental studies, it is found that SSWM 40×32 performs the better in different aspect, so it can be a good alternative for strengthening of RC elements compared to other FRP materials.
„Mit Geschlecht hat das aber nichts zu tun“. Über die Schwierigkeiten von Professorinnen, über Geschlecht (nicht) zu sprechen
Authors: Paulitz Tanja , Wagner Leonie
Published: June 2023

Historisch wie aktuell finden sich in Interviews mit Professorinnen Konstruktionen von Geschlechtsneutralität, mit denen sie versuchen, die Widersprüche zu bearbeiten, die sich aus der Meritokratienorm der Wissenschaft und gleichstellungspolitischen Versprechungen einerseits und alltäglichen Erfahrungen in der Hochschule andererseits ergeben. In einer aktuellen qualitativen Untersuchung an Hochschulen (Universitäten, Hochschulen für angewandte Wissenschaften, Kunst- und Musikhochschulen) wurden erstmals seit den 1980er-Jahren Erzählungen von Professor:innen über alltägliche Erfahrungen bzw. deren Einordnung in eine vergeschlechtlichte Organisationskultur analysiert. Zentraler Befund ist die regelmäßige und proaktive Dethematisierung von Geschlecht als relevanter Faktor für erfahrene Marginalisierungen. Diese Aussagen werden im vorliegenden Beitrag nicht als nahtlose Deskription einer heute erreichten Geschlechtsegalität gedeutet, sondern als Praktiken der Bürgschaft für eine vermeintlich erreichte geschlechterneutrale Hochschule sowie als eigene Statussicherung auf der Position als Professorin und meritokratisch anerkannte Leistungsträgerin.
The Particular and the Universal. Reflections on Knowledge Production, Human Diversity and Human Rights in Universal Design
Authors: Lid Inger Marie
Published: June 2023

This article discusses universal design as a concept and strategy in light of human diversity. Inspired by the German-American philosopher Hannah Arendt, plurality is understood as a condition of humanity. From this recognition of human diversity, the term ‘universal’ is analysed, focusing on the ambivalences inherent in the concept. I argue that universal design, as a human rights concept, must respond to human plurality and avoid the ableist risk of excluding persons and groups of people, when implementing universal design strategies. Interdisciplinary knowledge, education and skills are important for the practice of universal design. According to Article 4 of the Convention On The Rights Of Persons With Disabilities (CRPD), new research is needed to apply universal design strategies in different contexts. I then focus on disabling barriers in education and research. I conclude by arguing for developing a culture of access and embedding universal design strategies in disability research recognising the socio-cultural aspects and human plurality.
Optimizing SPARQL queries over decentralized knowledge graphs
Authors: Aebeloe Christian , Montoya Gabriela , Hose Katja
Published: June 2023

While the Web of Data in principle offers access to a wide range of interlinked data, the architecture of the Semantic Web today relies mostly on the data providers to maintain access to their data through SPARQL endpoints. Several studies, however, have shown that such endpoints often experience downtime, meaning that the data they maintain becomes inaccessible. While decentralized systems based on Peer-to-Peer (P2P) technology have previously shown to increase the availability of knowledge graphs, even when a large proportion of the nodes fail, processing queries in such a setup can be an expensive task since data necessary to answer a single query might be distributed over multiple nodes. In this paper, we therefore propose an approach to optimizing SPARQL queries over decentralized knowledge graphs, called Lothbrok. While there are potentially many aspects to consider when optimizing such queries, we focus on three aspects: cardinality estimation, locality awareness, and data fragmentation. We empirically show that Lothbrok is able to achieve significantly faster query processing performance compared to the state of the art when processing challenging queries as well as when the network is under high load.
Hybrid deep model for brain age prediction in MRI with improved chi-square based selected features
Authors: G.S Vishnupriya , Rajakumari S. Brintha
Published: June 2023

Ageing and its related health conditions bring many challenges not only to individuals but also to society. Various MRI techniques are defined for the early detection of age-related diseases. Researchers continue the prediction with the involvement of different strategies. In that manner, this research intends to propose a new brain age prediction model under the processing of certain steps like preprocessing, feature extraction, feature selection, and prediction. The initial step is preprocessing, where improved median filtering is proposed to reduce the noise in the image. After this, feature extraction takes place, where shape-based features, statistical features, and texture features are extracted. Particularly, Improved LGTrP features are extracted. However, the curse of dimensionality becomes a serious issue in this aspect that shrinks the efficiency of the prediction level. According to the “curse of dimensionality,” the number of samples required to estimate any function accurately increases exponentially as the number of input variables increases. Hence, a feature selection model with improvement has been introduced in this paper termed an improved Chi-square. Finally, for prediction purposes, a Hybrid classifier is introduced by combining the models like Bi-GRU and DBN, respectively. In order to enhance the effectiveness of the hybrid method, Upgraded Blue Monkey Optimization with Improvised Evaluation (UBMOIE) is introduced as the training system by tuning the optimal weights in both classifiers. Finally, the performance of the suggested UBMIOE-based brain age prediction method was assessed over the other schemes to various metrics.
Work readiness and barriers to employment during COVID-19 for individuals with Neurofibromatosis Type 1 (NF1)
Authors: Buono Frank D. , Polonsky Maxim , Marks Asher , Larkin Kaitlyn , Sprong Matthew E.
Published: June 2023

BACKGROUND: The global COVID-19 pandemic has directly impacted individuals with rare diseases who are attempting to maintain or obtain employment. Individuals with Neurofibromatosis Type 1 are especially at risk due to their disease. OBJECTIVE: The current study compared the impact that generalized anxiety and quality of life had on work readiness and potential barriers that individuals with NF1 had in gaining and maintaining employment during the COVID-19 pandemic to a sample of healthy individuals using a moderating mediation analysis. METHODS: A total of 213 individuals (105 NF1; 108 Healthy individuals) were recruited to complete a cross-sectional study in which a series of work-related assessments were completed. RESULTS: Generalized anxiety had an indirect effect on work readiness, fully mediated by barriers, with higher anxiety associated with more barriers, in turn negatively correlating with work readiness; quality of life partially mediated the effect of barriers on work readiness and was negatively associated with the former and positively with the latter. CONCLUSION: Quality of life was a mediator of the relationship between perceived employment barriers and work readiness for the healthy individuals group only. The results imply that anxiety and quality of life are significant mediators and require consideration in terms of evaluation and facilitation of employment maintenance and acquisition.
Experiences of the medical profession: A qualitative study using narrative facilitators
Authors: Bourquin Céline , Orsini Sandy , Stiefel Friedrich
Published: June 2023

BACKGROUND: Physicians’ narratives are means to approach and comprehend the practice of medicine, and physicians’ embedment in their work and the healthcare context. OBJECTIVE: This study aimed to explore physicians’ professional experiences and to examine how they are affected by factors related to their inner (psychological) and outer (institutional and social) worlds. METHODS: The study was designed as an exploratory qualitative study based on “narrative facilitators” (NF). Their goal is to encourage storytelling and to support the narrative process. The analytic approach was specific for each NF. RESULTS: Thirty-three physicians participated in the study. The findings showed a focus on the transformations of a profession, the need for physicians to adapt in terms of role and status, and their withstanding of conflicting projections from the public and patients (NF: press articles). The institutional context was described as not welcoming and impersonal (NF: photo-based story). When reacting to the quotes from their peers, participants showed a variety of un-patterned stances with respect to different aspects of medicine and the medical profession, illustrating heterogeneity with regard to professional attitudes and identities (NF: quotes from biographies/narrative accounts). Finally, findings also indicated that physicians often limited their narratives to a description of the materiality of the elements put into play (NF: blurred video sequences). CONCLUSION: Disenchanted physicians are not beneficial, neither for the patient nor for the health care system, and their feeling of being worn out may do harm and negatively affect themselves and their families.
Measuring the usability of a novel ergonomic chinrest during violin playing: A feasibility study
Authors: Mann Stephanie , Juhl Carsten Bogh , Paarup Helene M. , Søgaard Karen
Published: June 2023

BACKGROUND: Playing the violin often requires a rotated and lateral flexed neck, leading to potential neck and shoulder problems. An ergonomic chinrest (EC) with or without a shoulder rest (SR or WSR) may enhance neutral neck positioning, but the feasibility of the EC needs to be studied. OBJECTIVE: Our goal was to evaluate the usability of the EC for a two-week familiarisation period, including aspects such as playing performance, comfort level, and emotional response (e.g., feelings about using the product) among a group of violinists. METHODS: A one-arm feasibility study was conducted to assess the feasibility of violinists playing with EC every day for two weeks. Six violinists who usually played with SR were included and asked to divide their daily playing time equally between SR and WSR. Feasibility outcomes were measured as adherence (days), compliance (playing hours per day) and usability (5-point Likert scale and open-ended questions). Compliance was achieved with a minimum of 25% playing time. RESULTS: Daily violin playing with EC showed high adherence of 89.3%. Compliance with the 25% play time criterion was met for SR, but not for WSR. Low playing performance (median 45.8 points difference), long confidence time (two violinists failed to reach a confidence level) and mainly negative feedback (26 out of 33 comments) were found in WSR compared to SR. CONCLUSIONS: The feasibility of playing WSR was low and negatively impacted playing performance. As a result, a larger-scale study will only evaluate the EC with SR due to greater feasibility.
The effects of dual screen layout on neck-shoulder muscle activity and head-neck posture variability during computer tasks
Authors: Fang Fei , Huo Faren , Feng Yiran
Published: June 2023

BACKGROUND: Larger dual screens have been widely used during office work and their biomechanical exposure should be explored. OBJECTIVE: To investigate the biomechanical effect of two dual screen layouts on neck-shoulder muscle activity and the variability of head-neck posture in computer users. METHODS: A preliminary study of the user-preferred dual screen angles was carried out in V-shaped and L-shaped layouts. Twenty healthy participants aged 19 to 26 years were recruited and assigned to perform reading, typing, and searching tasks for 30 minutes in both workstation layouts. Electromyography was measured at bilateral cervical erector spinae (CES), sternocleidomastoid (SCM), and upper trapezius (UT). The head-neck lateral bending, rotation, and flexion angles were recorded. The visual analog scale (VAS) was used to evaluate visual strain. RESULTS: The muscle activity at the left UT and right CES sites when using the V-shaped layout was significantly higher than the L-shaped. There were significant differences in head-neck rotation and flexion angles between the two layouts in reading and typing tasks. In the searching task, there was no significant difference in the head-neck rotation and flexion angles between the two layouts. The visual strain score was significantly higher in the V-shaped layout. CONCLUSION: The CES and UT muscles displayed higher levels of activation while using the V-shaped layout in comparison to the L-shaped layout. The head-neck rotation and flexion angles differed due to varied types of work when using V-shaped and L-shaped layouts.
Digital tools for prevention through design application: A systematic review
Authors: Oliveira Vanessa S. , Santos Cynthia Jordão de Oliveira , Vasconcelos Bianca M.
Published: June 2023

BACKGROUND: Prevention through Design (PtD) is a safety initiative that increases the ability of eliminating risks before construction. Implementing digital tools for PtD is an innovative way to help identify embedded risk in design phase by automating a process that is currently time consuming and extensively dependent on designers’ experience. However, there is a lack of known digital safety tools available to professionals. OBJECTIVE: The aim of this article is to systematically review published research on the development of digital tools for PtD in order to point out existing processes and limitations. METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analyzes (PRISMA) guidelines were used to search publications in Scopus database. Initially, 148 publications were found, but after applying the filters, thirteen publications were read and included in this review. RESULTS: Quantitative results showed few publications and quantitative results detailed the studied digital tools workings and what limitations prevent their full implementation by designers. CONCLUSION: Although 53.84% of methods are automatic, existing barriers such as the inability to consider schedule, and to provide a complete database challenge the validity of these tools. Therefore, PtD still poses a research gap for future research on safety matters.
The Radiative Corrections to the Maxwell Equations
Authors:   Department of Physical Electronics, and The Laboratory of the Plasma Physics, Masaryk University, Brno, Czech Republic, Pardy Miroslav
Published: June 2023

The one-loop radiative correction to the photon propagator can be graphically represented by the Feynman diagram of the second order. The physical meaning of this diagram is the process Y-> (e- + e+) -> Y , where Y is denotation for photon, and e-, e+ is the electron-positron pair. It means that photon can exist in the intermediate state with the electron and positron as virtual particles. The photon propagation function based on such process with electron-positron pair e-, e+ is derived. The modified Lagrangian of electromagnetic field is derived supposing the modified Green function of photon. The Schwinger source methods of quantum field theory was applied. Then, the modified Maxwell equations are derived from the new Lagrangian.

A comparison is made between Greaves, E. D., Bracho, C., Gift, S., and Rodrigues, A. N., 2021. A Solution to the Pioneer Anomalous Annual and Diurnal Residuals, Progress in Physics, vol. 17, 2, p. 168. and Hodge, J. C. 2006. Scalar potential model of the Pioneer Anomaly.arXiv: astro-ph/0612567v1. Both papers suggest the Pioneer Anomaly obser- vation is due to the signal being modified by a characteristic of space that is influenced by the Sun and Earth. The papers differ by what that characteristic is and how it influences the signal. The former paper uses “energy density” (a scalar) which is proportional to distance (r-4) from bodies. All the characteristics of the former paper were accounted in the original calculation of the Pioneer Anomaly. The latter paper used a vector proportional to r-2, a gravitational force exerted on photons that was not accounted. The different treatment of r by the latter provides a more accurate treatment of the periodicities and all 10 anomalous characteristics of the Pioneer Anomaly. The conclusions of the former that the velocity of light is Galilean additive and the use of the “gravitational density” are not supported.
Ukrainian National Stylistics of Stage Vocabulary of Modern Children's Musical
Authors:   Kiev National University of Culture and Arts, Kiev, Ukraine, Belymenko Liliana
Published: June 2023

The article is devoted to the issue of the reflection of Ukrainian national stylistics in the productions of children's musicals on the stages of domestic theaters in 2010-2020s. It was revealed that the appeal to the traditions of folk culture takes place in the context of the leading modern trends in stage art, thanks to the synthesis of which a unique color of the artistic image of the performance is achieved. The research revealed that the most important cultural and artistic principles of the Ukrainian national stylistics of the stage vocabulary of the modern children's musical are the reproduction of a living tradition and the author's directorial approaches to the interpretation of folklore forms. In some cases, the representation of the Ukrainian folk tradition in a historically authentic form is characteristic, but mostly the directors emphasize a certain stylization and conventionality of the national color - traditional elements are used to create the atmosphere of a folk tale in a modern interpretation. Characteristic stylistic coloring is achieved by using authentic material, folk chants, dances, elements of traditional Ukrainian decor, creating well-known folklore images.

An experiment was conducted with efficient Rhizobial isolates from the rhizosphere soil of Dibru-Saikhowa Biosphere Reserve (DSBR) forest of Assam, India in both laboratory and field condition with black gram. The purification, authentication, characterization and screening of efficient isolates viz. MDB1 (Microbial Diversity Bacteria), MDB9, MDB11, MDB12 and MDB15 have been done in vitro experiment in Gibson’s tube and Leonard jars. Lone inoculation of these five isolates in black gram with prominent parameters like dry weight (g, plant-1) of shoot and root, chlorophyll content (mg, g-1fresh wt.), N & P content (g/plant) and yield (kg, ha-1) were recorded in field condition. Dry weight of nodule (51 g, plant-1), shoot (7.80 g, plant-1) and root (3.55 g, plant-1) was observed high in MDB11 inoculation while low (nodule= 34, shoot= 5.60 and root= 2.30 g, plant-1) in MDB15. The N & P content showed high (3.15 & 1.86 mg/plant in shoot and 1.69 & 1.06 mg/plant in root) in MDB11 inoculation comparison to others. Subsequently, the highest productivity (460.48 kg, ha-1) of the test crop observed in due application of MDB11 while lowest (365.32 kg, ha-1) in MDB15.

Pyrrosia belonging to Polypodiaceae, commonly known as felt ferns is characterized by its simple leaves and the presence of stellate hairs in the frond. Despite the great range of variability within the species, accessions of P. heterophylla (L.) Price from Kerala have not been extensively examined. The present study aims at the morpho-anatomical comparison of accessions. The samples were collected and variable characters such as habitats, shape, colour, thickness, width, length of sterile fronds, length, width and spore arrangement of fertile fronds, scales and the internal structure of the rhizome, stipe, and lamina of 20 accessions were examined and photographed using Carl Zeiss photomicroscope. Observations of the epidermis, including stomata and stellate hairs, were also made. Coded binary states of characters were used for developing a data matrix, which was further analysed. Cluster analysis using the UPGMA method were done from which a dendrogram was constructed which represents the taxonomic relationships among the species. In terms of the morphology and anatomy of the plant parts, three of the 20 accessions differed from P. heterophylla (L.) Price.

An ethno-medicinal survey was carried out to collect information and its documentation of the folk knowledge and diversity of uses of ethno-medicinal herbaceous plants from the tribal and rural inhabitants of the Cachar district of Assam during the period of 2018–2021. The area comprises of diverse medicinal herbs as well as diversity in ethnic groups and culture practices associated with plant diversity. The indigenous knowledge of folk medicinal herbs was collected from the field through personal communication with the inhabitants of the remote villages of the district and through repeated enquiries from local folk. In the present survey, a total of 112 species under 101 genera of herbaceous plants belongs to 60 families were collected, identified and documented. The study reveals that the ethnic and rural peoples of the survey area are depending on traditional medicinal plants for many of their primary health care. During the survey, it was found that due to anthropogenic activities (i.e., deforestation, construction of roads, urbanization and modernization, etc.) many of the important medicinal herbs used by the tribal and ethnic groups became rare, endangered and threatened. Therefore, it is necessary to develop the conservation and propagation activities of these ethno-medicinal herbs for future generations.

From the family Bignoniaceae, Stereospermum suaveolens (Roxb.) DC. and Stereospermum colais (Buch.- Ham.ex Dillw.) are source plants for the classical ayurvedic drug named ‘Patala’. It is group member of ten plants known as ‘Dashmoola’. Present review encompasses all the ethnomedicinal information along with the domestic uses available regarding Patala. For this, published ethnomedicinal claims from 32 books related to ethnomedicine, 59 botanical and state floras available in central library of ITRA, Jamnagar and online (website of Botanical Survey of India) and 30 research articles were reviewed till August 2022. Collected data is depicted in tables under the headings like name and place of the reporting area/state and tribes, local names, useful part with indication and method, mode of application external or internal, etc. Stereospermum species are reported in approximately 19 states and 48 tribes of India. Its root-root bark, stem-stem bark, leaves, fruits and seeds are used in 46 disease conditions. Fever, hiccough, asthma, cough are some of its major therapeutic indications. Among the useful parts, root & root bark have maximum claims in 26 disease conditions. Stem & stem bark have 19 disease applications followed by leaves in 12, flowers in 10 and seeds in 3. Parts of Patala also have domestic uses in preparation of dye, drinks, furniture and as fuelwood. This attempt shows multidimensional qualities of Stereospermum species. Its ethnomedicinal claims coincides exactly with its indications in classical Ayurvedic texts and can be incorporated in pharmacological and clinical studies to further strengthen the evidence.

Tea established as a refreshing stimulant beverage rich in caffeine, sugars, lipids, and aromatic substances demonstrates a wide variation in the quality depending on the type of brand. In this study, five different black tea market brand samples collected from the local market were evaluated for adulterants, caffeine content, and antioxidant activity. Based on the laboratory tests, artificial colors, azo colours, and sand was detected in 80% of tea samples. Caffeine content was determined by the chloroform method. The tea samples exhibited a wide range of antioxidant activity (3.29±1.03 to 15.96±1.2) assayed by the DPPH free radical scavenging method. These investigations could go a long way in promoting the production of quality foodstuff in the larger interest of consumers.
