A doença cárie é tida como um grande problema de saúde bucal em todo o mundo. Dessa forma, é caracterizada como uma doença comportamental diretamente ligada aos hábitos alimentares, e à falta de higienização efetiva. A odontologia trabalha em busca de diminuir procedimentos invasivos, como as intervenções operatórias cuja intenção é favorecer um ambiente onde ocorra a paralisação da atividade cariogênica. Portanto, a remoção parcial do tecido cariado é considerada uma ótima opção quando a ideia é a de se realizar um tratamento que vise a reabilitação estética e funcional do paciente, atrelado à promoção de saúde bucal. É um procedimento realizado de forma menos invasiva, favorecendo a diminuição de estresse ao paciente odontopediátrico. O objetivo deste trabalho é realizar uma revisão de literatura, tendo como finalidade a de se ampliar o conhecimento a respeito da remoção seletiva de tecido cariado em dentes decíduos e sobre a utilização da técnica de coroa metálica - Hall Technique. Tratamentos minimamente invasivos que removem o tecido cariado infectado, preservando tecidos afetados, e utilizam materiais de alta viscosidade com liberação de flúor como o cimento de ionômero de vidro, têm demonstrado bons resultados na manutenção e prevenção de progressão da cárie dentária. O presente estudo se trata de uma revisão literária, que considera artigos de revisão, relato de casos clínicos, monografias e de livros publicados nas bases de dadosk Medline, Lilacs, Scielo e Google Acadêmico.

Published: April 2024

Aim: To determine the normal range of serum levels of total 25(OH)VD in Iraqi healthy adult subjects and to relate its level with demographic profile and socioeconomic status. Materials and Methods: This cross sectional study was carried out at Iraq and the samples were collected during the period from August 2019 to January 2020. It included 649 adult subjects apparently healthy, from three governorates (Baghdad, Al-Anbar and Al-Basrah), Investigations included serum measurement of total 25(OH)D in all included individuals by using ELISA technique. Age, gender, marital state, blood pressure, smoking, sunshine exposure (%), hours of exposure/day, percentage of body surface area exposed, body mass index (BMI) subgroups, waist circumference (WC) subgroups, diet type, sport type and time, geographic factor (governorate) were measured and / or calculated and the levels of 25(OH)D were studied according to each of these factors. Results: The mean ± SD level of 25(OH)D in total (n=649) studied Iraqi subjects was (16.29 ± 8.22 ng/ml), with women were significantly deficient than men (15.76 ± 6.89 ng/ml, 17.14 ± 6.85 ng/ml; p < 0.01 respectively). However, there was no significant differences in mean values of serum 25(OH)D levels among studied governorates, subgroups of BMI, WC, marital status, smokers and nonsmoker and subgroups of age. The mean value of serum 25(OH)D was found to be decreased in January, October and November as well as according to diet and sport types. There was significant positive correlation between total 25(OH)D and sun exposed surface area, sun exposure duration and with sun exposure area. Conclusions: The mean (±SD) value of serum total 25(OH)D in Iraqi healthy subjects was 16.29 ng/ml (±8.22) reflecting the actual body status of this vitamin with lower concentration in women than in men. Type and time of sport and diet type were the major vitamin D dependent factors.

An Epistemological Approach to The Translation of Tenses and Aspects in English-French and French-English Contexts
Authors: Akpaca Servais Martial
Published: April 2024

This paper delves into the complexities of translating tenses and aspects, particularly in English-French and French-English contexts, advocating for an epistemological approach that entails a meticulous examination of source language (SL) tense and aspectual elements, as well as considerations of situational context, textual nature (e.g., direct speech, narrative, retrospection, anticipation) and pragmatics. The concept of tense inherently encompasses aspect, which delineates the structure of actions conveyed by verbs. Aspect may denote completeness or incompleteness, iteration or punctuality, semelfactivity, telicity, atelicity, frequency, and permanence, among other qualities. Employing a qualitative method, this paper first outlines the theoretical underpinnings of the notions discussed, followed by concrete examples. The study reveals that tense, originally derived from the concept of time, is intricately linked with aspect and action. Aspect, moreover, extends beyond linguistic realms to encompass philosophical (e.g., Aristotelian aspect) and metalinguistic dimensions. A cross-linguistic examination of tense and aspect unveils multifaceted relationships encompassing lexical, philosophical, semantic, syntactic, pragmatic, and strategic dimensions, necessitating further elucidation.

Authors: White Rickie , Nordman Carl , Smart Lindsey , Leibfreid Teresa , Moore Bill , Smyth Regan , Govus Tom
Published: April 2024

In 2003, ?vegetation communities? were selected as one of the highest priority vital signs of importance across the Cumberland Piedmont Network (CUPN) parks (Leibfreid et al. 2005). The protocol described in this document will address all aspects of monitoring this vital sign. The primary monitoring goal is to assess status and trends of ecological health for park forest vegetation communities, including key communities of management concern where possible.

By assessing status and trends for key metrics, we can obtain a more complete picture of the status of forest vegetation communities in the parks and the trends in ecological health for these communities. For instance, by repeatedly measuring one key metric of plant species composition within the same plots over the years, we can determine how quickly and profoundly invasive plant species are affecting the native vegetation and whether specific species are appearing or disappearing from plots. This information can be critical in helping land managers detect trends before they are visible qualitatively and setup more specific studies to determine the root causes of such trends.

This protocol is intended for use by the Cumberland Piedmont Network and was designed to efficiently collect, analyze, and disseminate scientifically credible information to help park managers and researchers understand how the forest vegetation communities of the parks are changing.

To fully implement this protocol, read the entire document and all appendices, as well as the standard operating procedures (SOPs; published separately). The appendices and SOPs contain detailed information on implementation not provided in the main body of the document. Datasheets have been designed so data collection is sequential starting with SOP 3: Site Selection and Plot Establishment?Version 1.48 (CUPN 2023a) and ending with SOP 10: Soil Measurements?Version 1.1 (CUPN 2023b). The SOPs are intended to serve as a reference for field teams implementing this protocol. It is anticipated field teams will be knowledgeable of their content and maintain a copy for reference as part of the required field equipment.

Published: April 2024

У статті висвітлено істотні позиції щодо проблеми виховання соціальної зрілості особистості, атрибутивних ознак цього феномену в науковому дискурсі. Актуалізовано необхідність виховання соціально зрілої особистості зі сформованими соціальними настановами, ціннісним ставленням до соціальних норм, до інших людей, здатної до активного включення в соціальне життя країни, до здійснення соціальних змін й активної самозміни. Виявлено зростаючий науковий інтерес до зрілості особистості як однієї з домінантних характеристик процесів соціального функціонування в сучасному світі. Констатовано наукову полеміку щодо змісту та об’єктивних критеріїв, що характеризують людську зрілість. Конкретизовано сутність дефініції «зрілість особистості» у довідкових виданнях і наукових візіях учених. Виокремлено риси особистісної зрілості. Встановлено, що феномен соціальної зрілості є більш дослідженим у західній психологічній теорії й акумулює загальні уявлення про соціальні якості людини, виконувані нею соціальні функції, ступені володіння індивідом своєю суспільною сутністю, а отже, розглядається у різних ракурсах індивідуального самовизначення. Узагальнено, що атрибутом соціальної зрілості особистості є віддзеркалення двобічного зв’язку, за якого не лише діяльність формує соціальні якості особистості, а й акумульований в індивіді особистісний потенціал втілюється для вдосконалення цієї діяльності та суспільних відносин.

Authors: Tiwari Rajib , Timilsina Menaka , Banstola Susmita
Published: April 2024

Introduction: Inhalation technique and medication adherence are essential prerequisites for achieving optimal therapeutic effects in patients with chronic obstructive pulmonary disease (COPD) and asthma. Although there are various effective treatments for respiratory disorders, disease control in these patients is still sub-optimal because of incorrect inhalation techniques and poor medication adherence. Pharmacist-led interventions have  demonstrated a positive impact on improving inhalation technique, better medication adherence, and thus subsequently improving the quality of life of patients.
Methods: Search engines such as PubMed, Google Scholar, and Science Direct were used to identify the relevant information using keywords: Chronic Obstructive Pulmonary Disease, Asthma, Pharmaceutical care, Pharmacist Intervention, Medication Adherence and Inhalation Technique. The relevant articles that were published between 2005 to 2021 were included and reviewed for the Pharmacist-led interventions to improve medication adherence, inhalation technique, and quality of life of patients with COPD and asthma.
Results: Of the 300 articles screened, a total of 14 articles met the inclusion criteria and were included for review. Pharmacist-led interventions help to improve the medication adherence, inhalation technique, and quality of life of patients with COPD and asthma. Similarly, the articles mentioned in this review found that the interventions provided by the pharmacist to COPD and asthma patients were cost-effective in terms of reducing hospitalization rates and severe exacerbation rates.
Conclusion: Our review concluded that the pharmacists’ interventions have a significant improvement in medication adherence and inhalation techniques with the enhancement of therapeutic effects in adult patients with COPD and asthma.

Introduction: The number of studies that explore people with both alpha and beta thalassemia mutations is still low, not only in Vietnam but around the world as well. We conducted this study to explore genotypes and phenotypes of pregnant women who have both alpha and beta thalassemia mutations in comparison to those who don’t have any thalassemia mutations and those who have either alpha or beta thalassemia mutations.
Methods: This was a cross-sectional study conducted in the National Hospital of Obstetrics and Gynecology from September 2020 to July 2021 on medical records of 6929 pregnant women who attended the hospital between 2015 and 2021. Mutation analysis was performed by the α-Globin Strip Assay (Vienna Lab, Austria) and Strip Assay MED (Vienna Lab, Austria).
Results: There were 18 pregnant women with both alpha and beta thalassemia genes, in which only SEA mutation caused alpha thalassemia and nearly 70% of beta thalassemia was caused by CD26 mutation. In comparison with pregnant women who didn’t have any thalassemia genes, those with both mutations had higher RBC, RDW, HbA2 and lower HGB, HCT, MCV, MCH, MCHC, and HbA1. We only see the statistically significant difference in HbA1 and HbA2 between those with both mutations and those with either alpha or beta thalassemia mutations.
Conclusion: In conclusion, our study showed that there were differences in genotype and phenotype between pregnant women with both alpha and beta thalassemia mutations and other types of thalassemia as well as those without thalassemia.

Published: April 2024

This research aims to explore and describe the implementation of the tourism park development program in Unamendaa Village. This research uses an inductive qualitative analysis. Inductive analysis is an approach that begins with field facts, analyzes them based on relevant theories and arguments, and ultimately yields a conclusion. The results show that implementing the Tourism Park development program in Unamendaa Village faces several significant obstacles related to communication, resources, disposition, and bureaucratic structure. Regarding communication, the Village Tourism Park program’s socialization needs to be implemented optimally. Regarding resources, there needs to be more BUMDes Organizers in managing the Village Tourism Park. Concerning disposition, although the Village Government has entrusted development responsibility to BUMDes, there still needs to be clarity in the tax payment mechanism. Additionally, the suboptimal bureaucratic structure adds complexity to the obstacles, including issues of supervision, coordination, facility provision, and communication between the Village Government and the community, which collectively hinder the achievement of the Village Tourism Park development goals. Therefore, it is recommended that the Village Government improve communication effectiveness with the community through increased frequency and more innovative socialization methods to ensure that information about the Village Tourism Park development is evenly distributed to all community members. For BUMDes, it is suggested that resource deficiencies be addressed by training organizers in tourism park management and operations and clarifying the division of responsibilities between organizers and traders to prevent role overlaps. Traders are expected to cooperate more closely with BUMDes Organizers, especially regarding compliance with the established tax payment mechanism. The community is encouraged to actively participate in every process of the Village Tourism Park development, in aspects of planning, execution, and supervision, to create good collaboration between the Village Government, BUMDes, traders, and the community, aiming for the sustainable and beneficial development of the Village Tourism Park for all parties in the future.
A Fictional Depiction of the Peculiarities of the African Female Gender Experiences in the Diaspora
Authors: Ndamira Joan Kyarimpa , Kyarimpa Jovuret
Published: April 2024

The issue of Africans in the Diaspora stretches historically to the time when Africa began having contact with the outside world, particularly the Arabs, Chinese, Turks, and others. Beginning with the 16th to the 18th C, the contacts heightened during the Trans- Atlantic Slave Trade. Thereafter, Africans have found themselves in the Diaspora for many reasons. This has elicited a myriad of reactions to their experiences in the Diaspora. Therefore, the study sought to investigate the fictional depiction of African immigrant experiences in the Diaspora. It was guided by two objectives namely: to establish the fictional depiction of the peculiarities of the African female experiences in the Diaspora, and to investigate the narrative styles adopted to convey these experiences. The focus was on four novels: Americanah (2013), Minaret (2005), We Need New Names (2013), and The Seasons of Thomas Tebo (1986). The study was library-based research. Its significance is in the fact that it gives a snapshot of the two sides of migration- positive and negative. The results revealed that the African female gender faces indescribable discrimination, undergoes the pain of assimilation into the foreign culture, has to work two jobs in order to sustain life in the Diaspora, is always haunted by the fear of aging and having nothing to show for it, plus several other challenges. The diasporic spaces also catalyse character changes in these migrants. As a result, they adopt confusing mannerisms, fail to wish away homesickness, become two-faced hypocrites, are subdued, submissive and in extreme cases – go through a mental breakdown. It was discovered that migrant fiction is narrated through humour, flashback, irony, detailed description, suspense and other stylistic techniques. The study concluded that migration is now a contemporary and central theme in much of African fiction, especially by a new generation of African writers

The main problems of structures dynamic calculation using earthquake accelerograms are analyzed. The problems of setting design accelerograms, modeling rigidity and damping structure properties, as well as substantiating the seismic resistance criteria of structures are considered. The design seismic action generated for the structure and for the construction site is considered. Requirements are formulated for the accelerogram digitization and for the number of design accelerograms for a construction site, sufficient for assessing the structure seismic resistance. The difficulties of constructing design accelerograms and taking into account in calculations the accumulation of damage in a structure during seismic vibrations are indicated. It is noted, that calculations using accelerograms of strong earthquakes can be easily made only for structures with given parameters of limit states. For linear calculations, the problem of taking the system damping into account is analyzed. The criteria for limit states limiting the work of plastic deformation forces and the damageability of a structure are considered.

Published: April 2024

In continuation of the work on the establishment of optimal geometric dimensions of structures intended for the construction of buildings using additive technologies, the main structural approaches for the reinforcement of walls and floors are determined. As the main variant of the overlap device, a rotary segmental structure with a half-wave length of 0,6 m was adopted, while the angle of inclination of the connecting element between the upper and lower belt is 270, a similar design solution was adopted for the wall structure. The calculation is carried out by the finite element method. Modeling is performed by shells with absolutely rigid bodies at the interface of the wave and the belts of structures. The results of the reinforcement calculation show that for the construction of walls with a total thickness of 400 mm, reinforcement should be performed only constructively at the point of the overlap support, for the pivoting segments of the overlap with a total thickness of 250 mm, reinforcement is mandatory and does not depend on the length of the span. The diameter of the reinforcement for spans in the range of 3,0-8,4 m of the overlap structure and various payloads is calculated, according to the results of the reinforcement selection, it is concluded that the spans of the rotating segments of the overlap should be performed no more than 7,2 m. The article was prepared as part of the implementation of the state task in the field of science for the implementation of scientific projects implemented by the teams of scientific laboratories of educational institutions of higher education subordinate to the Ministry of Education and Science of the Russian Federation under the project “New materials and technologies for the construction of buildings, structures and their elements using robotic additive systems” (No. FEWN-2023-0004).

(2015), Del Rosario (2020), Restrepo (2020), entre otros. Metodológicamente se estableció una Revisión documental apoyada en un tipo de investigación documental de diferentes bases de datos electrónicas y textos disponibles en bibliotecas virtuales. Se compararon posturas de los autores sobre la conceptualización de las variables cultura organizacional y organizaciones inteligentes. Dentro de los resultados encontrados se logró comparar las distintas fuentes bibliográficas que permitieron establecer las definiciones conceptuales que dieron rumbo a construcciones teóricas referidas a las temáticas abordadas en la revisión documental. Todo esto permitió concluir que existen diversidad de posturas entre los autores referidas a la cultura organizacional, sin embargo, los autores mantienen presente que dentro de ellas se realiza una referencia a creencias, valores y normativas a cumplir de parte de los empleados, sin dejar de ver que dentro de lo que corresponde a organizaciones inteligentes existen diferentes formas en las que estas se pueden nombrar y que van desde organizaciones que aprenden hacia las denominadas autocualificantes. De igual forma se concluye que es posible que dentro de las organizaciones inteligentes se manejen escenarios para crear culturas organizacionales inteligentes.
A Trade-off Ranking Method: Case of Extreme Solutions Redundancy
Authors: Muhammad Akram Ramadhan Ibrahim  , Nor Izzati Jaini  , Sergey Utyuzhnikov
Published: April 2024

In the trade-off ranking (TOR) method, the determination of the extreme solution (ES) is the main step before ranking the alternatives. ES reflects the best value of one criterion in a conflicting multi-criteria problem. However, the redundancy in selecting the ESs occurs because of the redundancy in some of the criteria values. Based on the stated problem, an improved TOR method is introduced in this paper to cater the redundant ES problem. An example is used from the literature to test the improvisation. The result indicates the implementation of the TOR method provides a better solution since it satisfies two conditions which are the highest value for different weights and the least compromise values in average weights. This verifies the reasonableness and effectiveness of the TOR method.

Published: April 2024

The construction sector is one of the important contributors to economic growth in Malaysia through Malaysia’s GDP significantly. In this research, 35 companies from Bursa Malaysia, which are selected from construction sector under main market covered year 2006-2021 have been studied. The Construction 4.0 Strategic Plan (2021-2025) was launched by CIDB Malaysia to transform construction industry by utilising the innovative technologies to build a more effective, sustainable and integrated system. This research aims to examine the efficiency performance of each construction firm so that it can be advantaged to policymakers, investors, as well as stakeholders. Through these insights, it can assist the stockholders to make wise decisions in term of how to relocate the resource and investment opportunities. This research uses the DEA model with financial ratios, which included three inputs: debt to assets ratio (DAR), debt to equity ratio (DER), current ratio (CR) and three outputs: earning per share (EPS), return on equity (ROE) and return on asset (ROA) to fill the research gap on the effectiveness of construction sector in Malaysia as there has yet to be a comprehensive investigation by other researchers. The efficiency of the companies was analysed by DEA model and only 8 companies: DKLS, KERJAYA, MERCURY, MERGE, MGB, PRTASCO, PTARAS and ZECON are examined as efficient companies. Lastly, the potential improvement for each inefficient company also have been determined.

Teachers' Perceptions about Distributed Leadership Practices in South Asia: A Case Study on Academic Activities in Government Colleges of Bangladesh (BY IJISRT)
Authors: Kumar Mojumder Arup , Haque Munzurul , Mondal Joyprokash
Published: April 2024

The concept of teacher leadership is relatively a new entry into the educational terminology and interpretation in the context of developing countries. The distributed perception on leadership may pave attention about activities orientation, not in position of teacher.  Aims & Objectives In a government college in Bangladesh, this study investigates the perspectives of faculty members regarding the implementation of distributed leadership practices in academic affairs. Furthermore, it investigates the perspectives of educators regarding the challenges associated with the implementation of distributed leadership within that particular institution. This study aims to investigate teachers' perspectives on distributional leadership and the obstacles that hinder its implementation in the academic activities of government colleges in Bangladesh.  Methodology In order to accomplish the research objectives, this study employed qual-quant methods, specifically an opinion survey and interviews with teachers of a government college in Bangladesh who were selected for the study. Participants were purposefully selected from among the teachers who possessed expertise in distributed leadership. Document review for three-dimensionality verification is another method of data collection. Analyzing qualitative data, this investigation employs thematic analysis. Result- The study identifies several obstacles that hinder the implementation of the distributed leadership approach in all academic activities at the chosen government college in Bangladesh. These challenges include a lack of employee commitment to the organization, limitations in management, apprehension regarding power loss, and cultural factors.  Contribution The findings indicate that distributed leadership has been implemented in certain academic activities, and instructor opinions indicate that this leadership style should be utilized in additional activities.

How Well is the International Celestial Reference System Maintained in Official IAU Implementations?
Authors: Malkin Zinovy
Published: April 2024

The International Celestial Reference Frame (ICRF) based on the VLBI-derived positions of 608 extragalactic radio sources was adopted by the International Astronomical Union (IAU) in 1998 as the first realization of the International Celestial Reference System (ICRS). Later, in 2009 and 2020, two extended ICRF versions, ICRF2 and ICRF3, respectively, were released. The latter is adopted by the IAU as the current implementation of the ICRF in the radio band. In the meantime, the Gaia mission delivered three versions of the optical ICRS realization in 2016, 2018, and 2022 with an accuracy similar to that achieved by VLBI-based ICRF. The Gaia-CRF catalogs were linked to the ICRF under no-rotation conditions and thus may suffer from ICRF systematic instability if the latter is substantial. In this work, a new analysis was performed to assess the long-term stability of radio and optical ICRS realizations. Based on the 16-parameter vector spherical harmonics expansion of the differences between the three ICRF catalogs, it can be concluded that the mutual orientation between them is at a level of a few tens of microarcseconds, while the components of the glide vector and E
2,0 term are several times greater. A comparison of the three Gaia-CRF catalogs with the ICRF3-SX showed that for the latest Gaia-CRF catalog, Gaia-CRF3, all rotational and deformation components are below 20 μas except for the E
2,0 term, which is several times greater. For both ICRF and Gaia-CRF catalogs, the evolution of the source position errors is also tracked.
Implication of the Velocity Dispersion Scalings on High-mass Star Formation in Molecular Clouds

This paper is aimed at exploring the implications of velocity-dispersion scalings on high-mass star formation in molecular clouds, including the scalings of Larson’s linewidth–size (σ– R) and ratio–mass surface density (

L

– Σ; here

L

= σ/R
0.5). We have systematically analyzed the σ parameter of well-selected 221 massive clumps, complemented with published samples of other hierarchical density structures of molecular clouds over spatial scales of 0.01–10 pc. Those massive clumps are classified into four phases: quiescent, protostellar, H ii region, and PDR clumps in an evolutionary sequence. The velocity dispersion of clumps increases overall with the evolutionary sequence, reflecting enhanced stellar feedback in more evolved phases. The relations of σ– R and

L

– Σ are weak with the clump sample alone, but become evident when combined with others spanning a much wider spatial scales. For σ– R, its tight relation indicates a kinematic connection between hierarchical density structures, supporting theoretical models of multiscale high-mass star formation. From the

L

– Σ relation, cloud structures can be found to transition from overvirial state (α
vir > 2) to subvirial state (α
vir < 2) as they become smaller and denser, indicating a possible shift in the governing force from turbulence to gravity. This implies that the multiscale physical process of high-mass star formation hinges on the self-gravity of subvirial molecular clouds. However, the influence of turbulence may not be dismissed until large-scale clouds attain a subvirial state. This is pending confirmation from future multiscale kinematic observations of molecular clouds with uniform observing settings.
