Several countries have placed groundwater spatial information inventories in a significant position in groundwater management. However, this effort has not been found in Indonesia. This is probably due to limited references. This study aims to determine the spatial information of groundwater as a basis for inventory. The research also aims to identify the capabilities of Arc GIS online as a medium for inventorying groundwater spatial information. As a preliminary study, Sitimulyo Village, Bantul Regency, Special Province of Yogyakarta was used as the study area. Data was collected through field surveys. Spatial interpolation was used for data analysis. Based on the results of the study, it is known that the free groundwater in the majority of the research area is 6.7 to 9.5 meters deep. Studies on electrical conductivity, temperature, and alkalinity also indicate that groundwater quality is good. Arc GIS online can be used as a medium for inventorying groundwater information. Easy accessibility, supported by simple data management and updating, is the advantage of Arc GIS online.
Technology-Based Music Interventions to Reduce Anxiety and Pain Among Patients Undergoing Surgery or Procedures: Systematic Review of the Literature
Authors: Park Sunghee , Lee Sohye , Howard Sheri , Yi Jeeseon
Published: June 2024

Background

Hospitalized patients undergoing surgery or procedures may experience negative symptoms. Music is a nonpharmacological complementary approach and is used as an intervention to reduce anxiety, stress, and pain in these patients. Recently, music has been used conveniently in clinical situations with technology devices, and the mode of providing music is an important factor in technology-based music interventions. However, many reviews have focused only on the effectiveness of music interventions.

Objective

We aimed to review randomized controlled trials (RCTs) of technology-based music interventions for reducing anxiety and pain among patients undergoing surgery or procedures. We examined the clinical situation, devices used, delivery methods, and effectiveness of technology-based music interventions in primary articles.

Methods

The search was performed in the following 5 electronic databases: PubMed, MEDLINE (OvidSP), CINAHL complete, PSYCINFO, and Embase. This systematic review focused on technology-based music interventions. The following articles were included: (1) RCTs, (2) studies using interactive technology (eg, smartphones, mHealth, tablets, applications, and virtual reality), (3) empirical studies reporting pain and anxiety outcomes, and (4) English articles published from 2018 to 2023 (as of January 18, 2023). The risk of bias was assessed using the Cochrane Risk of Bias tool version 2.

Results

Among 292 studies identified, 21 met the inclusion criteria and were included. Of these studies, 9 reported that anxiety scores decreased after music interventions and 7 reported that pain could be decreased before, during, and after procedures. The methodology of the music intervention was important to the results on anxiety and pain in the clinical trials. More than 50% (13/21, 62%) of the studies included in this review allowed participants to select themes themselves. However, it was difficult to distinguish differences in effects depending on the device or software used for the music interventions.

Conclusions

Technology-based music interventions could help reduce anxiety and pain among patients undergoing surgery or procedures. The findings of this review could help medical teams to choose a practical methodology for music interventions. Future studies should examine the effects of advanced technology-based music interventions using smart devices and software that promote interactions between medical staff and patients.
Assessment of Acceptability, Usage, and Impact on Caregivers of Children With Autism’s Stress and Mindfulness: Multiple-Method Feasibility Study of the 5Minutes4Myself App’s Mindfulness Module
Authors: Larson Elizabeth , Mattie Rebecca L , Riffkin Sophia A
Published: June 2024

Background

Caregiver wellness programs need to be easily accessible to address caregivers’ constraints to participation.

Objective

We aimed to assess the feasibility of 5Minutes4Myself app’s mindfulness module (usability, usage, and impact on caregivers’ levels of mindfulness and perceived stress).

Methods

Before and after participation in the 5Minutes4Myself program, 15 participants were asked to complete the Perceived Stress Scale (PSS) and Five Facet Mindfulness Questionnaire (FFMQ). Data on the usage of app-delivered meditations were collected electronically via the app, and app usability was rated on the Modified System Usability Scale. Analyses assessed participants’ frequency of use of app-delivered meditations, app usability, and changes in participants’ stress and mindfulness post intervention.

Results

Overall, participants completed 10.9 minutes of mindfulness meditations per week and rated the app 76.7, indicating above-average usability. Related samples t tests (2-tailed) found that group PSS (t10=1.20, P=.26) and FFMQ (t10=−1.57, P=.15) pre- or postintervention mean scores were not significantly different. However, a visualization of pre- and post-PSS and mindfulness scores suggested there was a group of responders who had decreased stress with increased mindfulness. This was confirmed via an individual change analysis. The effect size of the FFMQ scores (d=0.47) suggests there may be treatment effects with a larger sample. A hierarchical multiple regression analysis examined the degree mindfulness impacted perceived stress; 20% of the variance in participants’ perceived stress could be attributed to increases in self-rated mindfulness (P=.04) when controlling for preintervention stress levels.

Conclusions

Caregivers found the app highly usable and on average used low-dose levels of mindfulness meditations (10 min/wk). For responders, increased mindfulness was related to stress reduction to population-based levels.

This work developed a selectively modified electrode for measuring the Fe(II) ions in continuous integration using voltammetry techniques. The study assessed various aspects, such as linearity, scan rate, repeatability, and real sample analysis. The experiment is performed using differential pulse voltammetry (DPV). The findings of the study indicated that the voltammetry method exhibited a regression line of y = 36.507 ln(x) + 990.73, with a correlation value of 0.9627, with an optimum scan rate of 20 mV/s and good repeatability over five times measurement. On the other hand, when comparing the results using the UV-Vis spectrophotometric technique, the regression equation was found to be y = 0.20438x − 0.06987, with a correlation value of 0.99583. Notably, the voltammetry measurement outperformed the UV-Vis method since it allowed analysis of Fe(II) at concentrations up to 6.35 × 10−4 ppm (or 1.00 × 10−11 M), while the UV-vis measurement could only analyze up to 1.5 ppm (or 2.36 × 10−5 M). Consequently, the developed technique proves to be superior to the other methods for the analysis of Fe(II).
Qualitative Geochemical Analysis of the 2004 Indian Ocean Giant Tsunami Deposits Excavated at Seungko Mulat Located in Aceh Besar of Indonesia Using Laser-Induced Breakdown Spectroscopy
Authors: Mitaphonna Rara , Ramli Muliadi , Ismail Nazli , Arief Nasrullah Idris
Published: June 2024

Laser-induced breakdown spectroscopy (LIBS) was employed to characterize the geochemical signatures layer by layer of 2004 Indian Ocean tsunami deposits in Seungko Mulat Village, Aceh Province, Indonesia. In the LIBS experimental setup, a Nd-YAG laser beam is directed towards the deposit samples, and the resulting atomic emission lines from the laser-induced plasma are captured using a spectrometer. Our analysis reveals terrestrial indicators (Fe), heavy metals (Cu, Cr, Co, Cd), and increased emission intensity of Mg, Ca, Al, K, Si, Ba, N, and O in the 2004 Indian Ocean tsunami layers. The emission intensity ratios of several elements in the 2004 Indian Ocean tsunami deposit layers, namely Ca/Ti, Si/Ti, and K/Ti, unveil notable disparities among the elements evaluated. This indicates the possibility of utilizing these ratios as reliable geochemical markers to differentiate the layer by layer of tsunami deposits. LIBS surpasses XRF in detecting nearly all elements simultaneously and identifying both light elements and specific heavy metals (Ba, Cu, Cr, Co, Cd, Pb, Ni, V, W), exceeding XRF's detection capabilities. This study emphasizes the effectiveness of LIBS as an advanced optical technique, offering speed and promise in analyzing layer-by-layer geochemical markers of the 2004 Indian Ocean tsunami deposits in Seungko Mulat Village.

Authors: Mahmood Rasha Shakir , Hussian Dhiaa Hadi
Published: June 2024

This review is mainly on the relevance of graphene aerogels for energy storage systems highlighting their distinct properties and applications. Today, electronic devices such as smartphones, laptops, and other electrical appliances have become the axe of our daily lives. As a result, electrical energy is required for these devices. Despite the discovery of renewable energy sources as an alternative to fossil fuels, the construction of energy storage systems is still necessary to store energy. Lithium-ion batteries and supercapacitors are considered essential systems for this purpose and have witnessed tremendous development in recent years. The efficiency of these systems depends on the structure of the materials used in their formation. Graphene oxide and graphene aerogel materials improve the properties of energy storage systems in terms of stability of charging and discharging cycles, longevity, and reduction of combustion incidents resulting from ordinary compounds. However, the development of graphene aerogels faces challenges in improving their mechanical properties, the cost of their preparation, and their high agglomeration ability in solvents. Therefore, intensive efforts are needed to develop these materials for a new revolution in energy storage.

Published: June 2024

In recent years, green synthesized nanomaterials have garnered wide interest due to its inherent features like rapidity, cost-effectiveness, and environmentally friendly technique. The green synthesis of Zinc oxide nanostructures (n-ZnO) using two kinds of plant extract, lavender (Lavandula angustifolia) and meniran (Phyllanthus niruri), were discussed and their antibacterial activities were compared. Characterization by means of X-ray diffraction (XRD), Fourier transform infrared (FTIR), and field emission-scanning electron microscopy/energy dispersive X-ray spectroscopy (FE-SEM/EDS) were used to confirm the successful formation of n-ZnO using both plant extracts. The antibacterial activity of the n-ZnO synthesized from two different plant extracts was tested against Klebsiella pneumoniae and methicillin-resistant Staphylococcus aureus (MRSA). The results show that both n-ZnO has antibacterial activity against MRSA. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values for n-ZnO synthesized from meniran extract were 78 and 156 mg/mL, respectively, while MIC and MBC values for n-ZnO synthesized from lavender extract were 156 and 312 mg/mL, respectively. These results confirm that the n-ZnO prepared from meniran extract is more effective in inhibiting MRSA than the n-ZnO prepared from lavender extract. This study proves that plant-based n-ZnO has anti-microbial activities and may serve as antimicrobial therapeutics.

Facilitating Productive Struggle in an Online Secondary Education Mathematics Methods Course: Experiences of Pre-Service Teachers
Authors: Casler-Failing Shelli
Published: June 2024

This research investigated preservice teachers’ (PSTs) experiences with productive struggle in an online environment, and how it influenced their pedagogical knowledge. This action research study reports on secondary mathematics pre-service teachers (PSTs) who completed mathematical tasks in weekly synchronous Zoom sessions to develop their understanding of productive struggle. Vygotsky’s (1978) Social Constructivist Theory and the growth mindset framework (Boaler, 2016; Dweck 2006; 2008) provided the lenses through which the research was designed and analyzed. Findings show that presenting opportunities for PSTs to experience productive struggle informs their pedagogical practice, and that providing this experience in an online environment is possible. PSTs gained an increased understanding of the importance of collaborative work, asking purposeful questions, and the alignment between productive struggle and improved mathematical understanding.
“Surviving and Thriving”: An Autoethnography of a Black Afro-Caribbean Early Career Teacher in a Northern Ontario First Nation Community
Authors: Briscoe Patricia , Robinson Jody-Ann
Published: June 2024

The beginning years of a teacher’s career can be an overwhelming experience, and combined with being in an isolated, fly-in community, particularly during a pandemic, can be debilitating. This qualitative research is aimed to support and account for the story of a Black Afro-Caribbean, early career teacher (ECT) in a Northern Ontario First Nation (FN) community over a three-year teaching placement. The goals were to use her stories for reflection, inspiration, and guidance to support other ECTs, and to provide recommendations to teacher-education programs to lessen attrition and increase retention among ECTs in FN school placements. An autoethnographic method was used to identify key themes in her narratives to better understand her experiences of surviving and thriving. Although this ECT was significantly tested about her decision to become a teacher, support, empathy, resiliency, and governing one’s practice with clearly defined moral and ethical principles rooted in the belief that every child can learn helped her survive and thrive. The conclusion was that ECTs in FN school placements need, among other things, a willingness to be vulnerable and resilient.
Linguistic intuition in the system of teaching Russian as a foreign language at the pre-university stage
Authors: Urunova Raisa D.
Published: June 2024

The relevance of the study is due to the lack of methodological complexes designed to develop linguistic intuition among foreigners studying the Russian language at pre-university stage. Foreign students at the initial level of education usually use linguistic intuition formed in their native language, but observations show that a full-fledged linguistic intuition in Russian-language speech communication is based on the automatic use of elements and constructions of the Russian language. The purpose of the study is to substantiate the need for consistent use of tasks that contribute to the automated speech skills and stimulate linguistic guess in the process of teaching Russian as foreign language. The following methods were applied: observation of the communicative activities of students learning the Russian language with the proposed methodology, analysis and synthesis of results, as well as observation in order to identify difficulties in achieving automaticity of speech skills and the use of linguistic intuition. The research was conducted at the elementary and basic levels of teaching the Russian language to Iranian students of medical and biological specialties at the Preparatory Faculty of the Kazan (Volga Region) Federal University. A methodology has been developed, based on the system of phonetic, lexical-grammatical and text tasks for classroom and independent work. The training complex uses elements of critical thinking to form and improve speech and cognitive skills that will help foreign students develop the ability to independently solve various communicative problems. Provided that tasks for developing intuition are regularly completed at classroom, it seems promising to achieve freedom of speech behavior of foreign students in communicative acts of various types.
Case system in learning Russian as a first and second foreign language
Authors: Ceytlin Stella N. , Kruglyakova Tatiana A.
Published: June 2024

The task of creating innovative technologies for teaching Russian as a native, as a non-native and as a foreign language, taking into account the age of students, their cognitive abilities and features of the first language, is relevant. The solution of this problem requires a fundamental psycholinguistic study of the processes accompanying the formation of the language mechanisms of children and adults. The aim of this research is to specify the ideas about mastering the category of Russian case in various conditions of language acquisition. The method of comparative analysis of the processes of mastering Russian case in monolingualism, simultaneous child bilingualism, studying Russian as a foreign language and Russian language acquisition by a foreign-speaking child in the process of communication, was used. The material was collected during longitudinal observation of the speech of primary school students from St. Petersburg, who were native speakers of Turkic and Caucasian languages. The classification of errors in selecting and constructing case forms is proposed. The ways of access to the mental lexicon and the mechanisms of procedural grammar rules formation are described. The conclusion is that there is the imbalance between the cognitive and communicative development of a foreign child and the level of language proficiency, which leads to a detailed, but grammatically unformed statement, characteristic of a successive natural bilingual. When Russian-speaking child resorts to retrieving ready-made frameworks of prepositional case constructions from memory, the foreign child independently constructs them in speech, preferring to use basic and reduced forms. In the future, it is necessary to develop a unified toolkit for studying grammar mechanisms formation and to increase the empirical base of the study. The information about speech ontogenesis obtained as a result of the study must be taken into account for developing scientifically based methods of teaching Russian as a non-native language and as a foreign language.
Textbooks on reading in Russian for Chinese universities over the past 30 years: analysis and prospects
Authors: Li Yan
Published: June 2024

Textbooks are the basis for implementing the curriculum and an important support in teaching activities. They play an important role in foreign language teaching, representing teaching materials that combine the characteristics of the time, learning objectives, advanced teaching concepts, and patterns of self-learning. The aim of the research is to identify trends and problems in the sphere of preparation and publication of teaching aids for reading in Russian in China. The author analyzed 84 manuals on reading in Russian published in China over the last 30 years. Special attention was paid to the 4 most representative books published at different times. Comparative-typological method, as well as methods of induction and mathematical processing were used. The comparative analysis of teaching aids was carried out considering the aspects of the purpose of creation, structure, content. The features of universal (comprehensive) and professional-specialized reading textbooks, including auxiliary teaching materials are considered. The necessity of creating a series of high-quality textbooks is emphasized, and the ways of solving this problem are determined. The author has deeply explored the alternatives of composing Russian reading textbooks from the point of view of a system of multifunctional thematic content, integration of intercultural and national-specific elements, and multipolar learning.
Corpus explication of semantics of the dichotomous concept “Life - Death” in the Russian linguistic picture of the world
Authors: Lyi Siqi , Polyakova Elena V. , Dzholdasbekova Bayan U.
Published: June 2024

The conceptual dyad “Life - Death” in the Russian linguistic picture of the world is analyzed. The relevance of the research is conditioned by the existential significance of the studied phenomenon in the axiological field of the Russian linguistic picture of the world. The aim of the study is to conduct corpus analysis of the conceptual dyad “Life” and “Death”. The research material includes 70 poetic units containing the nuclear lexemes “Life” and “Death” in the Russian National Corpus. The poetic units are semantically complete contexts of poems by Russian poets (M. Tsvetaeva, M. Voloshin, S. Esenin, Z. Gippius, etc.). Descriptive method, conceptual analysis, method of linguistic-cultural commentary, contextual analysis, corpus method were applied. It was concluded that the concepts “Life - Death” reconstruct the dominant features of the Russian linguistic picture of the world, which is characterized not only by qualitative heterogeneity, but also by a certain bipolarity in the subject's behavior (agenticity vs passivity, providentiality vs activity, etc.). Such semantic parameters of the concepts “Life” and “Death” were established as transience and uncontrollability of life; life as an element, where a person is not an active subject, but an object for external forces; transience of life and its unpredictability; belief in life after death; death as a transition to otherness. The explanatory context for adequate commenting of conceptual meanings is formed.

In archaeology, landscape is studied as a cultural, social, and environmental process that simultaneously influences human thinking and is impacted by human actions. From such a perspective, the establishment of cemeteries, too, results from human choice with respect to the environment, engendering a specific mortuary landscape. This is, overall, a little-studied field in the history of research on the Iron Age in Latvia. Even so, a continuous development of ideas may be traced, both in terms of the broadening of the range of issues addressed, proceeding from basic description of the cemetery’s location to analysis of its significance in the landscape, and in terms of the growing diversity of approaches and methods employed, moving from simple observation of the surrounding area to interdisciplinary studies and various kinds of data analysis.

Rakstā apkopoti un analizēti tēli, kuri Rīgas arhitektūras dekorā parādījās 20. gadsimta pirmajā gadu desmitā un kuri alegoriskā veidā atspoguļo progresa un sociālās cīņas idejas. Jau kopš 19. gadsimta beigām progresa tēmu Rīgas arhitektūrā visbiežāk pārstāvēja Saules simbols, kas tika atspoguļots divējādi – gan kā parasts Saules attēls, gan kā antīkā dieva Hēlija/Apollona tēls. Minētajā periodā šie simboli kļuva par ierastu arhitektūras dekora elementu. Tajā pašā laikā uz ēku fasādēm parādījās jauni un oriģināli mēģinājumi paust progresa idejas, piemēram, gaismu nesošas Artemīdas/Selēnes tēls Alberta ielā 2a un alegorisks atjaunotas cilvēces attēls uz ciļņa Miera ielā 54. Savukārt cīņas tēma īpaši spilgti izpaudās divās skulptūrās Tirgoņu ielā 4 un trijos ciļņos, kas veltīti Prometeja sižetam, Marijas ielā 18. Var secināt, ka 20. gadsimta sākumā Rīgas arhitektūras dekorā progresa un revolucionārās cīņas idejas tika attēlotas samērā bieži un izteiksmīgi, kas norāda uz tā laika sabiedrisko noskaņojumu.

Published: June 2024

Background: The field of orthobiologics traditionally utilizes cellular products, including bone-marrow aspirate concentrate (BMAC), micronized adipose tissue, and platelet preparations to address pain from degenerative processes, orthopedic injuries and medical conditions characterized by chronic inflammation and tissue degradation. For BMAC, maximizing the concentration of mesenchymal stem cells (MSCs) in a reduced volume is thought to allow for the therapeutic delivery of the cellular concentrate, secretome, and extracellular vesicles to a site of orthopedic injury or surgical repair. The extracellular matrix (ECM) within the bone marrow stroma contains collagens and proteoglycans known to regulate cell proliferation, migration, differentiation, and cell-cell communication among resident bone marrow cells. This study aimed to evaluate the cellular effects on MSC health and function when harvested to retain their native tissue stroma.
Methods: We evaluated a novel and unique processing method and device (BMAX™) to mechanically generate a purified MSC product derived from bone marrow in a nonenzymatic manner. BMAX™ products, including cells and stroma, were plated in MSC culture media and incubated for 3–14 days (P0-P1) before evaluation with flow cytometry for cell phenotyping and immunoassays for secretome profiling.
Results: The orthobiologic product containing three-dimensional stromal components can be produced in minutes using an automated bedside device requiring minimal benchtop space. We found increased MSC adherence, improved proliferative density in culture, and significantly elevated enrichment of stromal-derived MSCs versus traditional BMAC centrifugation-based preparations. Further, we demonstrate a unique secretome profile in BMAX™ versus traditional BMAC centrifugation-based preparations.
Conclusions: These qualities provide a novel and unique platform for autologous and allogeneic bone-marrow-derived therapy to better address inflammatory and destructive processes that may improve bone-marrow-derived cell therapies’ efficacy.

Em vista da Base Nacional Comum Curricular (BNCC), o estudo da Arte é dividido em quatro linguagens específicas, sendo elas; Artes Visuais, Dança, Música e Teatro. É exposto pelo documento a necessidade de desenvolver as habilidades propostas de acordo com os objetivos do conhecimento, além de trabalhar a reflexão (crítica, imaginativa e sensível) e autonomia dos alunos, embasadas nas próprias experiências pessoais de contato com a arte. Não obstante, no ensino de arte dentro de escolas, principalmente estaduais ou municipais, a leitura de imagens ainda é ignorada, junto aos objetos de arte presentes no consumo midiático dos alunos; que sem um respaldo sobre como operar no mar de informações visuais para reconhecer as origens e motivações do mundo artístico, deixam de aliar o processo da autossuficiência ao acúmulo de conhecimento teórico e imagético, proveitoso não só para o estudo das Artes Visuais como outras áreas de conhecimento. Em vista dessa concepção, a abordagem triangular se apresenta como um dos possíveis modos de facilitar o aprendizado. Assim, no presente trabalho foi dedicado um estudo em Artes Visuais, a partir de uma releitura da Abordagem Triangular e investigação da correlação entre consumo midiático e aprendizado pela leitura de imagens, por meio do preparo dos alunos para um olhar artístico crítico.
The effects of CEO duality, board size, and informal social networks on sustainable innovation and firm performance.
Authors: Dixit Krishna , Manna Reshmi , Singh Ankit
Published: June 2024

Corporate governance affects the ownership and control of a firm. Conflicts between agents, managers and shareholders caused the crises of WorldCom, Enron, Tyco and Lehman Brothers. Therefore, the impact of chief executive officer (CEO) duality or board size on sustainable innovation and performance of small and medium-sized enterprises (SMEs) is relevant for research and evaluation. This may reflect the CEO style that supports long-term business growth with limited resources to enhance accountability, fast decision-making, and minimise hindrances to governance, particularly in emerging markets like India. The finding will help SMEs in maintaining their long-term viability. The current study examines the impact of CEO duality, board size, and informal social networks on sustainable innovation, governance, and performance of Indian SMEs to enable management to assess the significance of factors that contribute to firms’ sustainable performance

Published: June 2024

In the realm of financial oversight and corporate management, forensic accounting (FA) holds a critical position, serving as a central control mechanism and being widely recognized as an essential component of corporate governance. FA plays a crucial role as a central control mechanism and is acknowledged as a pivotal element of corporate governance. Consequently, it needs to continuously adapt in response to shifts in corporate governance practices, while the role of internal auditors transforms to actively support corporate sustainability. The aim of this research is to assess the effectiveness of FA and explore its relationship with corporate governance, based on the relevant literature. Thus, the main objectives of the present study are to identify the internal control attributes that influence the quality of its performance and to evaluate how corporate governance contributes to enhancing the quality of FA.

Objectives: The current in-vitro study evaluated the push out bond
strength of three root canal sealers and the sealer/dentine interface
under SEM in teeth subjected to radiation. Methods: Eight mandibular
single rooted premolars were selected and divided into irradiated and
non-irradiated groups. Three middle third root sections from each tooth
were obtained and three canal like holes were drilled followed by
immersion in 2.5% NaOCl for 15 minutes and distilled water. Each hole
in the sample was filled with a different sealer and incubated at 37°C
for 7 days. After setting, push out bond strength test was performed
using universal testing machine followed by failure mode analysis under
compound microscope and SEM. The results were subjected to the normality
tests (Shapiro–Wilk). The bond strength values were evaluated by two
way ANOVA with a split-plot design and Post hoc Tukey’s test (a = 0.05)
using the SPSS 20 software (SAS, Cary, NC, USA). Results: The bond
strength test revealed a higher bond strength value for the non –
irradiated group compared to the irradiated group. Among the three
sealers tested, BioRoot RCS showed the highest bond strength value
followed by AH Plus and least by MTA Fillapex. BioRoot RCS showed least
number of failures among the sealers tested. Conclusion: Bio Root RCS
showed the maximum bond strength values with least failures irrespective
of radiation, thus it can be considered the choice of sealer in patients
undergoing radiotherapy. Clinical implications: It was known that
therapeutic radiation affected the dentin ultrastructure and the bonding
ability of sealer. In this study, BioRoot RCS showed better bond
strength than AH Plus and MTA Fillapex which could be due to the type of
bonding as well the elimination of EDTA from the irrigation protocol.

Importance: To provide a current evaluation of bibliometric
trends in the Otolaryngology literature focused on randomized controlled
trials (RCTs). RCTs hold an important role in research as bias
controlled assessments of clinical interventions. Objective:
The purpose of this study is to evaluate the proportion of published
RCTs in the Otolaryngology literature. Design: Quality
Improvement scoping bibliometric review. Setting: Published
articles in eight Otolaryngology journals from January 1, 2016 -
December 31, 2020. Main Outcomes and Measures: Included
articles were categorized as a RCT, secondary research, other clinical
research, case report, primary basic science, or other study type.
Additionally, studies were categorized as American, Canadian, British,
or other international origin according to the corresponding author’s
institutional address. The proportion of published RCTs were compared by
national origin and to an earlier bibliometric analysis investigating
Otolaryngology journal publications from 2008-2012 using Pearson’s
Chi-Squared testing with Bonferroni correction. Results: A
total of 6797 articles were reviewed and included for analysis. There
was a significant difference in the proportion of RCTs published by
national origin, 1.3% USA, 2.2% Canada, 2.7% UK, 3.4% other (p
< 0.01). There was a significant decrease in the proportion of
RCTs published from 2008-12 to 2016-2020 (3.1% vs. 2.3% respectively,
p < 0.01). Conclusions: Although the current study
analyzed only a select sample of all Otolaryngology research output,
this study suggests that North American researchers are publishing less
RCTs than researchers in other countries. Moreover, RCTs are declining
as a proportion of the published Otolaryngology literature over time,
which is a threat to the evidence base for current and future
Otolaryngological practice.

The study evaluated the impact of film on the knowledge of sickle cell disease (SCD) in the Obio-Akpor Local Government Area of Rivers State, Nigeria. The objective of the study was to find out the level that sickle cell-themed movies have helped increase respondents’ knowledge and attitudes towards sickle cell disease, and how respondents perceive the effectiveness of movies as a means of increasing their knowledge and understanding of sickle cell disease. The study was conducted using a survey design. The population of the study was 683,565. A sample size of 400 was obtained from the population size using the Taro Yamane formula and three selected communities were sampled. A purposive sampling technique was used to draw advocates and relatives of sickle cell disease for an online interview. The result of the analysis showed that sickle cell-themed films have not been effective in campaigning against sickle cell disease as there has been low awareness about the symptoms and treatment options of sickle cell disease even with film campaigns. However, movies have helped respondents understand the emotional and social impact of sickle cell disease on individuals and families. Also, while four out of the seven factors had a mean below the criterion mean of 2.50, the aggregate was above the criterion mean. To achieve effectiveness, it was recommended that community leaders and the government should fund and encourage filmmakers to create more health advocacy campaigns and sponsor more sickle cell-themed movies.

The Protected Areas Working Group of the IUCN National Committee for the UK assessed 23 types of designation of land and sea for biodiversity conservation against IUCN definitions of 'protected area' and 'other effective area-based conservation measures'. This assessment supersedes Statements of Compliance published in 2014, reassigns several categories on the basis of new information and understanding, and provides guidance to UK and devolved governments, and their agencies, on which types of sites should be incorporated within the Global Biodiversity Framework Target 3 total. There is a need for urgent investment in improving the management effectiveness of all sites considered to ensure they can all effectively contribute to the achievement of UK's 30x30 target.
Coordinated action across administration levels and assessments: key tools to reveal barriers to effective management of protected areas

We assessed protected area management effectiveness and identified attributes that limit the effectiveness of 21 protected areas in the State of Santa Catarina, southern Brazil. Of these, we assessed 10 areas under state-level administration for which a standardised assessment had not previously been conducted. For the 11 protected areas under federal administration, we obtained assessment data from the government. The protected areas were contrasted regarding the administration level and a list of attributes that could result in differences in management effectiveness between areas. We examined the relationship between protected areas' attributes and mean effectiveness using linear models. The same attributes were also related to management elements, namely context, planning, inputs, processes and outputs, using redundancy analysis. Management effectiveness and scores of management elements were found to be lower for areas either with unresolved land tenure, lacking management plans or updated ones, those under many pressures and threats, or those under state-level administration. Overall, we suggest that federal protected areas do better in at least these attributes or a combination of attributes not well-captured by single indicators than state-level protected areas. Reassessments should be regularly carried out across administration levels in order to effectively flag a barrier, clear it, and identify the next one to be tackled.

Orthodontic treatment in patients with periodontally compromised dentition often presents challenges, necessitating special considerations. This case report describes treatment of a 52-year-old female patient with advanced chronic periodontitis and pathologic tooth migration through an interdisciplinary orthodontic–periodontal approach. By integrating comprehensive periodontal treatment with strategic use of miniscrew-assisted rapid palatal expansion (MARPE) and careful consideration of the applied force systems, both functional and esthetic concerns were addressed without causing adverse periodontal side effects. This highlights the importance of thoughtful treatment planning and integration of periodontal care during orthodontic tooth movement in treating individuals with reduced periodontal health for successful and esthetically pleasing results.
Propiedades psicométricas de la escala de estrategias de aprendizaje ACRA-Mx en población universitaria mexicana
Authors: Juárez Lugo Carlos Saúl
Published: June 2024

El objetivo de este trabajo fue analizar las propiedades psicométricas de una versión abreviada de la escala ACRA, para lo cual se usó una muestra de 1010 estudiantes universitarios mexicanos. Si bien esta escala fue diseñada para evaluar las estrategias de aprendizaje en estudiantes españoles de educación secundaria, se ha implementado con alumnos universitarios de países de habla hispana, pero sin contar con evidencia de su validación. En concreto, se emplearon los cuestionarios ACRA y CEVEAPEU para medir las estrategias de aprendizaje, y el CHAEA para determinar los estilos de aprendizaje. La validez de constructo se determinó mediante análisis factorial exploratorio. La solución final dio como resultado un instrumento de 4 escalas, 21 factores y 68 reactivos, con una consistencia interna adecuada (alfa de Cronbach desde .779 hasta .862). Asimismo, se desarrollaron normas percentiles que facilitarán la interpretación de los resultados. En conclusión, se puede afirmar que la escala de estrategias de aprendizaje ACRA-Mx es un instrumento simplificado y homogéneo, con evidencia de validez y confiabilidad para evaluar las estrategias de aprendizaje en la población de estudio. Además, constituye una herramienta sólida para el trabajo psicoeducativo de tutores académicos, orientadores escolares y profesores interesados en mejorar el rendimiento académico y promover aprendizajes significativos en los estudiantes universitarios.

El objetivo de este estudio fue analizar el juicio evaluativo de los docentes de matemáticas sobre la dificultad de una muestra de ítems en los que los estudiantes mostraron alto y bajo desempeño en la Prueba PISA 2015 en Chile. Para ello, se elaboró una investigación con enfoque cuantitativo y un diseño exploratorio. Los participantes fueron 18 docentes de matemáticas, elegidos mediante un muestreo no probabilístico e intencional, que respondieron a una encuesta con preguntas de respuesta abierta y cerrada, la cual evaluaba cada ítem con base en cinco dimensiones: formulación del ítem, contenido, contextualización, habilidad y complejidad. Los resultados demuestran que el 40% de los docentes de matemáticas presentan dificultad para acertar con precisión respecto a los ítems en los que los estudiantes mostraron bajo desempeño. Sin embargo, tendieron a concordar en el 60% de las evaluaciones y a predecir en el 80% el desempeño de los alumnos en los ítems de alto desempeño. Según los docentes, los estudiantes tendrán más dificultades en ítems que miden una habilidad cognitiva superior, tienen baja familiaridad con el tipo de ítem y en los que la información se encuentra de forma implícita en el problema.
