Background

Secondary schools are increasingly supporting adolescents’ mental health and well-being, yet many teachers report that they lack the skills and confidence to do so. Building Educators’ skills in Adolescent Mental Health (BEAM) is a web-based training program developed to improve secondary school teachers’ knowledge and confidence in caring for students’ mental health.

Objective

This pilot study examined the preliminary effectiveness and acceptability of the BEAM program for improving mental health knowledge, attitudes, confidence, helping behaviors, and psychological distress among secondary school teachers.

Methods

A single-arm pilot trial was conducted from July to December 2019 among secondary school teachers located in New South Wales, Australia, who were employed in leadership positions responsible for managing student well-being (ie, Year Advisors). Participants had access to the BEAM program for 6 weeks. Self-report surveys, delivered at baseline, postintervention (6-weeks post baseline) and 3-month follow-up (19 weeks post baseline) were used to measure changes in training outcomes. Acceptability was assessed by program use, barriers, satisfaction, and participants’ perceptions of program effectiveness.

Results

A total of 70 secondary school teachers took part (mean age 36.5 years, SD 9.41 years, range 24-60 years). Significant improvements in confidence were reported at postintervention and 3-month follow-up. Significant improvements in helping behaviors were reported at 3-month follow-up only. There was also a significant reduction in psychological distress at postintervention. Participants agreed that the program content was easy to understand and relevant, but program completion was challenged by lack of time, competing priorities, and forgetfulness.

Conclusions

Findings indicated that a web-based training program may be beneficial for improving secondary school teachers’ abilities to care for students’ mental health; however, program modifications are required to increase training completions.

Analysis of Apps With a Medication List Functionality for Older Adults With Heart Failure Using the Mobile App Rating Scale and the IMS Institute for Healthcare Informatics Functionality Score: Evaluation Study
Authors: Diaz-Skeete Yohanca Maria , McQuaid David , Akinosun Adewale Samuel , Ekerete Idongesit , Carragher Natacha , Carragher Lucia
Published: July 2021

Background

Managing the care of older adults with heart failure (HF) largely centers on medication management. Because of frequent medication or dosing changes, an app that supports these older adults in keeping an up-to-date list of medications could be advantageous. During the COVID-19 pandemic, HF outpatient consultations are taking place virtually or by telephone. An app with the capability to share a patient’s medication list with health care professionals before consultation could support clinical efficiency, for example, by reducing consultation time. However, the influence of apps on maintaining an up-to-date medication history for older adults with HF in Ireland remains largely unexplored.

Objective

The aims of this review are twofold: to review apps with a medication list functionality and to assess the quality of the apps included in the review using the Mobile App Rating Scale (MARS) and the IMS Institute for Healthcare Informatics functionality scale.

Methods

A systematic search of apps was conducted in June 2019 using the Google Play Store and iTunes App Store. The MARS was used independently by 4 researchers to assess the quality of the apps using an Android phone and an iPad. Apps were also evaluated using the IMS Institute for Healthcare Informatics functionality score.

Results

Google Play and iTunes App store searches identified 483 potential apps (292 from Google Play and 191 from iTunes App stores). A total of 6 apps (3 across both stores) met the inclusion criteria. Of the 6 apps, 4 achieved an acceptable MARS score (3/5). The Medisafe app had the highest overall MARS score (4/5), and the Medication List & Medical Records app had the lowest overall score (2.5/5). On average, the apps had 8 functions based on the IMS functionality criteria (range 5-11). A total of 2 apps achieved the maximum score for number of features (11 features) according to the IMS Institute for Healthcare Informatics functionality score, and 2 scored the lowest (5 features). Peer-reviewed publications were identified for 3 of the apps.

Conclusions

The quality of current apps with medication list functionality varies according to their technical aspects. Most of the apps reviewed have an acceptable MARS objective quality (ie, the overall quality of an app). However, subjective quality (ie, satisfaction with the apps) was poor. Only 3 apps are based on scientific evidence and have been tested previously. A total of 2 apps featured all the IMS Institute for Healthcare Informatics functionalities, and half did not provide clear instructions on how to enter medication data, did not display vital parameter data in an easy-to-understand format, and did not guide users on how or when to take their medication.

Novel coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused more than 2,38 million deaths and more than 108 million cases confirmed in one year of the pandemic are massive upheavals in social life and economy in the international world. An effective vaccine is needed to prevent further morbidity and mortality. This research aims to identify the challenge in implementing mass vaccination in Indonesia which is related to the efficacy of the COVID-19 vaccine. We retrieve sources from relevant and published articles in Google Scholar, Pubmed, DOAJ and Science Direct of articles up to January 2021. The keywords used for gathering information were listed below. Vaccine efficacy is defined as the proportional reduction of a disease case in a group of vaccinated participants compared with unvaccinated participants. The study of vaccine efficacy is a cohort study that is an important vaccine trial method in the field. It is conducted randomly on a large scale by using a control-placebo. During the trials, the country which used the vaccine needs to maintain and observe the vaccine epidemiology. A trial roadmap is expected to identify the condition of the area epidemiologically. Vaccine efficacy is essential to be observed before implementing the vaccine in society. However, intensive socialization about the advantage of vaccines is mainly needed to prevent irrelevant information in social media about mass vaccination.

The review is devoted to the influence of the hydrogen isotope–deuterium on biological models of organisms and the biological activity of pharmaceutical substances.

The positions of the influence of deuterium on the properties of active pharmaceutical ingredients and excipients are examined from different perspectives. The first position reflects an increase in the kinetic isotope effect (KIE) in processes involving known pharmaceutical substances in aqueous solutions with a deuterium/protium ratio (D/H) below natural. For the first time, the dose-response diagram shows the identity of deuterium with essential trace elements, when a deficiency and excess of an element reduces the organism's vitality. Improved kinetic characteristics are demonstrated for the molecular and organism levels of different hierarchical gradations. In particular, they consist in the possibility of increasing the dissolution rate of substances by influencing the carbohydrate mutarotation processes and the optical activity of chiral substances, increased accumulation of essential elements in medicinal plants and other processes associated with a possible change in metabolic pathways in the cell and the organism as a whole.

The second considered position of the influence of deuterium is associated with the use of deuterated substances–new compounds or obtained by substitution of protium in known protium analogues. The KIE is presented, which is expressed in a decrease in the biotransformation rate as a result of deuteration, it allows predicting a rapid development of the new direction in the development of drugs. Having an identical therapeutic effect, deuterated analogs provide improved pharmacokinetic characteristics, such as reduced toxicity, blocked epimerization of optically active substances, and a change in the mechanisms of biotransformation. The obtained results make it possible to predict the mechanisms of the effect of deuterium on the biochemical transformations of pharmaceutical substances in the organism.

Performances indígenas y afrodescendientes en Argentina: recreaciones sonoro-corporales de lo “ancestral”
Authors: Citro Silvia Viviana , Broguet Julia , Rodríguez Manuela , Torres Agüero Soledad
Published: July 2021

A partir de las políticas públicas del Estado argentino en relación con las poblaciones indígenas y afrodescendientes, examinamos de qué manera las políticas culturales de las provincias de Formosa y Santa Fe, especialmente durante 2003-2015, tendieron a visibilizar y revalorizar las performances “ancestrales” de estos pueblos. Analizaremos cómo, frente a las interpelaciones multiculturales por performativizar las identidades étnico-raciales ante la sociedad hegemónica, los/as performers fueron estimulados/as a seleccionar, recrear y espectacularizar determinadas sonoridades, movimientos e imágenes inscriptas tanto en repertorios corporizados como en archivos; pero también, cómo en estos procesos de recreación sonoro-corporal de las memorias se construyen nuevos archivos, con la intención político-cultural de resguardar y legitimar una determinada versión de las posiciones identitarias étnico-raciales puestas en juego.
“El ángel de los perdedores”: una mirada antropológica sobre trayectorias delictivas, moralidades y experiencias espirituales con San La Muerte en una villa de Córdoba (Argentina)
Authors: Liberatori Marina
Published: July 2021

En este artículo analizaré el caso de dos residentes del barrio Villa La Tela, cuyas experiencias espirituales con San La Muerte regulan los sentidos con los que construyen valores morales y complejizan las relaciones con familiares y vecinos. Veremos cómo esto se vincula con el hecho de vivir en una zona periférica y empobrecida de la ciudad, socialmente estigmatizada. Mostraré de qué modo las trayectorias morales que ellos construyen —y que se asocian con el mal y el delito— se articulan con la de San La Muerte, con quien establecen relaciones recíprocas de confianza, respeto, amor y favores. Esto permite reflexionar sobre las fronteras fluctuantes y porosas entre el bien y el mal como categorías morales con las cuales las personas significan y dan sentido al mundo.
La canción protesta y los discursos de contracultura y resistencia durante la década de 1960 en Colombia
Authors: Katz-Rosene Joshua
Published: July 2021

Este ensayo examina tres movimientos contra-culturales que cautivaron a un amplio sector de la juventud en las principales ciudades de Colombia durante la década de los sesenta: el movimiento de la canción protesta, la subcultura del rock and roll, cuya identidad local se denominó nueva ola, y el nadaísmo, un movimiento literario de vanguardia. Analizo las correspondencias y discontinuidades entre las formas en que los participantes de estos movimientos concibieron los medios ideales para llevar a cabo la resistencia social, cultural y política. Sostengo que, si bien hubo tensiones fundamentales entre los “discursos de resistencia” asociados a cada una de estas corrientes contraculturales, su convergencia a finales de la década de los sesenta facilitó el surgimiento de una variante comercial de canción protesta.

Class I cavities (2mmx4mm) were prepared on flattened occlusal surfaces of fifty extracted human premolars and randomly assigned into five groups (n=10) according to the materials used: Beautifil Bulk-fill Restorative (BR); Beautifil Bulk-fill Flowable (BF); Beautifil Flow Flowable F10 (BF10); and Self-etch adhesive (SEA). Group A: SEA+BR; Group B: SEA+BF10+BR; Group C: SEA+BF+BR; Group D: SEA+BF10+SEA+BR and Group E: SEA+BF+SEA+BR. The samples were thermocycled for 500 cycles, then sectioned mesiodistally, polished and pre-treated prior to scanning electron microscopy (SEM) evaluation. From SEM images, measurement of adhesive and cohesive adaptation failures was recorded at multiple sites of the pulpal floor and in between materials. Data were analysed using one-way ANOVA and post-hoc Tukey tests (p<0.05). Cohesive failure in SEA was observed at the pulpal floor with the lowest percentage in Group A (5.14%), and highest in Group C and E (>16%). However, there were no significant difference among all groups. Adhesive failure was seen at the pulpal floor between SEA+BF/BF10/BR and between SEA+dentine with the highest percentage of gaps formed in Group A between SEA+dentine (6.62%) and SEA+BR (5.30%). Nonetheless, no significant differences were observed among all groups with p=0.89 and p=0.70, respectively. With the use of BF/BF10 at the pulpal floor, adhesive failure was reduced but resulted in increased of cohesive failure. However, both adaptation failures were absent between materials (BF/BF10 and BR) regardless with or without application of SEA.

This study is aimed to provide an insight into the types of treatment carried out by postgraduate students in the past 10 years. A retrospective study was carried out between November 2019 and February 2020 by deriving data from postgraduate students’ clinical logbooks of three different cohorts of Master of Clinical Dentistry (Restorative Dentistry in Conservative Dentistry) in 2010, 2013 and 2016. This retrospective data was systematically extracted from the records and tabulated categorically using an Excel spreadsheet (Microsoft Office Excel 2019). A descriptive analysis was carried out to further evaluate the results. Overall, the types of treatment carried out in the field of endodontics and fixed prosthodontics has changed in the past 10 years. An increasing trend is seen in the placement of all ceramic crowns and primary root canal treatment procedures, while a decreasing pattern is evident for secondary root canal procedures and placement of dental bridges.

Published: July 2021

Manuscript type: Research paper Research aims: This study aims to investigate the effects of safety climate and employee engagement on organisational citizenship behaviour (OCB). Design/Methodology/Approach: Drawing from the social exchange theory and flow theory, a theoretical framework was developed and tested using data collected from 610 freelance sewage workers. A questionnaire survey was used to collect the data, while structural equation modelling (SEM) analysis was used as the data analysis approach. Research findings: The results reveal that both safety climate and employee engagement have significantly positive impact on employees’ organisational citizenship behaviour amongst sewage workers in Indonesia. This finding indicates that although the sewage cleaners are often employed based on contract and may not be in a position to demand more from the organisations, they do appreciate the organisational commitment in producing a safe workplace environment. They, in return will demonstrate a higher engagement towards their work. Theoretical contribution/Originality: This study contributes to the organisational citizenship behaviour literature by examining how workplace environmental factors such as safety climate affects organisational citizenship behaviour. In the context of sewage cleaning, safety climate is important, as sewage workers are frequently exposed to and threatened by serious health problems. Yet, there has been a paucity of research on the sewage cleaning sector to understand the relationships. Research limitation/Implications: The study implies that when organisations are willing to improve safety climate, their employees will perceive improved safety climate, and then will have more engagement and organisational citizenship behaviour.
Konstantin Leontiev’s “Ascetic Philosophy”: Thesaurus and Context
Authors: Fetisenko Olga L.
Published: July 2021

A holistic and close study of journalism, works of art and letters of K. N. Leontiev allows the author of the article to show the formation of the writer’s views, designated by him at the end of his life with the words “my ascetic philosophy”, the context they existed in and his vocabulary changes. The work discusses Leontiev’s creative, philosophical and personal interest to the issues of life of the spirit, the dynamics of his views, it is shown, how in the 1860s Leontiev comes from an aesthetic interest in the Church and its political defense in consular posts to a thirst for faith. The author pays special attention to the idea and concept of obedience, which are associated with Leontiev's idea of ​​“transcendental egoism”, focusing on personal salvation. Behind the idea of ​​obedience, Leontiev thinks about self-condemnation. The writer and thinker clearly explains the interdependence and interdependence of two principles, the “world” and the “monastery”; for Leontiev, monastery culture becomes a synonym for Orthodox culture. Leontiev tried to introduce ascetic principles of discipline and “sobriety” into his own artistic creation, and not only into content, but also into “performance”, applying in practice the rules that he formulated later in his famous article Analysis, Style and Trends.
Principal Features of the Imaginal-geographic Germany in the Russian Travelogues of the Late 18th – First Half of the 19th Centuries
Authors: Zhdanov Sergey S.
Published: July 2021

The paper deals with the spatial images of Germany represented in Russian travelogues of the late 18th – first half of the 19th centuries. The text corpus studied from a semiotic perspective consists of works by A. T. Bolotov, D. P. Gorikhvostov, D. I. Fonvizin, N. M. Karamzin, S. A. Korsakov, W. K. Küchelbecker, F. P. Lubyanovsky, I. P. Myatlev, M. P. Pogodin, A. Ya. Klimov, V. N. Zinovyev. A set of principal features representing the imaginal-geographic Germany is determined. The center of this set is the motif of orderliness actualizing in two images — a rationally organized space in the spirit of the Enlightenment and an idyll based on the Arcadian myth. The other spatial characteristics of the patched-up Germany are cleanness, accuracy, closeness, narrowness, miniatureness connected with the concept of order. The ambivalence of Russian travelers’ perceiving the German loci is emphasized. The idyllic Germany is not only admired but also ironically travestied in Russian literature. The rationally organized, civilized German landscape is both praised for its comfortableness and criticized in the frames of its extreme forms for dehumanization.
“Thorough Bass”: on the History of a Musical Image in L. N. Tolstoy’s Novel Anna Karenina
Authors: Mozharova Marina A.
Published: July 2021

The article deals with the history of a musical term, transformed by L. N. Tolstoy in his novel Anna Karenina into imagery employed for the conveying of ideas about running farmlands in Russia, which are so important for the author and his character Konstantin Levin. Having chosen a musical term to express his idea in the most accurate way, Tolstoy draws parallels between various narrative arcs and certain parts in a polyphonic composition where the main role is that of the “thorough bass” which is Levin’s impressions of the household of an old and wise peasant. Quite expectable of the writer, who loved and studied music, this artistic solution seemed to be so unusual to the editors preparing the publications of Anna Karenina during the entire 20th century that they considered it to be a misspell of a copying clerk or a type setter. As a result, a polysemic musical term “thorough bass” was replaced by “fundamental basis”. Looking up in the autographs does not give the answer to the question, which of these two options is correct, as manuscript collection has not been fully preserved. The only formal source which allows a textual critic to reconstruct the initial version is the text of the first publication of the novel in the magazine Russky Vestnik (1875–1877) corrected by Tolstoy himself in 1877, in accordance with which Anna Karenina is being published in academic Complete works of L.N. Tolstoy in 100 volumes.
Nature Images in Russian Odic Poetry of the 18th – Early 19th Centuries: Functional Role and Influence on the Further Literary Process
Authors: Svyatoslavsky Alexey V.
Published: July 2021

The article is devoted to the functional role of nature images in the formation of the imaginary structure of Russian odic poetry of the 18th – early 19th centuries. Examples are taken from the odic poetry of Mikhail Lomonosov, Vasily Trediakovsky, Alexander Sumarokov, Mikhail Kheraskov, Gavrila Derzhavin, Dmitry Khvostov. An attempt was undertaken to answer two questions: the place nature images occupied in odic poetry in the era of its pride and, secondly, the possibility to find in the poetry of classicism, despite the condescending attitude towards it that developed later in the history of Russian literature, something that constituted an organic part of the Russian classics of the 19th and 20th centuries. The functional role of nature images in the odic genre is shown, which, as it seemed, by definition is alien to natural themes, being organically connected with the pathos of civic consciousness and the appeal to the themes of heroism, great personalities, and historical events. However, as it turns out in a number of cases, the very objects of nature evoke the poet's admiration as an impressive work of the Creator, in others, nature is a background that in a certain way enhances the impression of the very historical events that constitute the subject of odic poetry. The conclusion is made about a certain continuity in the depiction of nature – from odic poetry to Russian lyric poetry and prose of the 19th and 20th centuries.
Does an Upcycling Kimono Practice Support Recycle-Oriented Cultural Sustainability? Japanese College Students’ Perspectives
Authors: McCarthy Minako
Published: July 2021

Kimono (a traditional Japanese garment worn by women) has played an important role in Japanese indigenous cultural origins. Ecological and sustainable ideas have inherently existed in kimono culture within this lifestyle. Since the United Nations announced the Sustainable Development Goals (SDGs) in 2015, the Japanese government has focused on creating healthy spaces with a sustainable direction in mind. However, textile-related product recycling rates were relatively low in Japan at the time. This empirical study used SDGs as a conceptual framework to examine Japanese college students’ perceptions of kimono upcycling practices and challenges. A mixed method was used to analyze the data. An open-ended questionnaire was distributed to college students in June 2019 in Liberal Arts at a national women’s university (n=155). The findings showed that interest in kimono upcycling moderately correlated to those and an interest in western garments upcycling (.578; p<.01). The relationship between these variables was significant (Chi-square: 48.471; p <.001). In the qualitative analysis, a coding method was used to explore common themes of students’ awareness and knowledge of upcycling kimono practices and found four strong themes to be present. The students perceived that upcycled kimono items connected to preserving family memories, whereas others noted upcycled items were used for sustainable resources. Also, three common challenges were found: practicality, technical issues, and people’s awareness. Some students also associated items with Japanese cultural preservation. College students’ attitudes and perceptions towards cultural sustainability engagement could therefore be a crucial mediator during sustainable development drives.
