Abstract

Background
A preliminary study using laser fluorescence suggested that amorphous phosphate-containing orthodontic composites may prevent demineralisation around bonded orthodontic brackets.

Objective
To compare the microhardness of the enamel around brackets bonded with an amorphous calcium phosphate-containing orthodontic composite (ACP-containing) with the microhardness of the enamel around brackets bonded with a conventional composite resin.

Methods
Forty extracted upper premolars were used. Orthodontic brackets were bonded to the teeth with either an ACP-containing composite resin (N = 20) or a conventional composite resin (N = 20). The latter were used as the control. The crowns of all teeth were painted with an acid resistant varnish, leaving a 2 mm ring of exposed enamel around the brackets. The teeth were then subjected to a daily cycle of demineralisation for 6 hours and remineralisation for 18 hours for 21 days. Each tooth was sectioned and the microhardness of the enamel determined 25, 50, 75, 100 and 150 μm from the surface.

Results
The enamel was significantly harder 25 μm (p = 0.000) and 50 μm (p = 0.001) from the enamel surface in the teeth with brackets bonded with the ACP-containing composite resin as compared with the control teeth.

Conclusion
ACP-containing orthodontic composite resins may reduce the enamel decalcification found in patients with poor oral hygiene.

Abstract

Objectives
To compare the intrusive forces and labio-palatal moments generated at the maxillary incisors by a 0.017 x 0.025 inch reverse curve NiTi wire using self-ligating and conventional brackets.

Methods
Ten 0.017 x 0.025 inch reverse curve NiTi archwires were used with each of the following 0.022 inch bracket systems: Titanium Ortho (Ormco/Sybron, CA, USA), In-Ovation R (GAC International, NY, USA) and Damon System 3MX (Ormco/Sybron, CA, USA). The wires were inserted on bracketed maxillary Frasaco models, with segmented maxillary incisors. Simulated intrusion from 0.0-1.0 mm was performed on the Orthodontic Measurement and Simulation System, which recorded the intrusive forces and the labio-palatal moments at 0.05 mm increments. The data were analysed with the ANOVA and Scheffe tests.

Results
The intrusive forces were significantly different between all bracket types. The highest force was recorded with the conventional Titanium Orthos brackets (8.2 N), followed by the Damon 3MX brackets (6.3 N) and the In-Ovation R brackets (5.5 N). The moments were found to be significantly different between the conventional and the self-ligating brackets, but not between the two types of self-ligating brackets. The highest moments were recorded with the self-ligating brackets (16.6-16.9 N/mm), followed by the conventional brackets (10.8 N/mm).

Conclusions
The intrusive forces exerted on the maxillary incisors by a 0.017 x 0.025 inch reverse curve NiTi archwire during the final 1 mm of levelling are very high and beyond the necessary intrusive force level for these teeth. Lower intrusive forces, but higher labio-palatal moments, were recorded with the self-ligating brackets.

Authors: Ghoneima Ahmed , Abdel-Fattah Ezzat , Eraso Francisco , Fardo David , Kula Katherine , Hartsfield James 
Published: December 2023

Abstract

Objectives
To investigate the skeletal and dental changes induced by rapid maxillary expansion, using computed tomography (CT) scans and three-dimensional (3-D) reconstructed images.

Methods
Twenty patients (Mean age: 12.3 ± 1.9 years) who required rapid maxillary expansion as a part of their comprehensive orthodontic treatment underwent pretreatment (T1) and post-treatment (T2) CT scans. The T2 – T1 differences between selected skeletal and dental measurements on the coronal CT and 3-D volumetric images were compared using the Wilcoxon signed ranks test.

Results
At T2 the Maxillary alveolar width (4.5 ± 3.5 mm) was greater than the Maxillary base width (1.7 ± 0.9 mm). The greatest transverse dental change was in the Intermolar width (6.3 ± 2.1 mm and 2.7 ± 1.9 mm at the crown and the apex, respectively). On the 3-D volume, significant increases occurred in the Bicondylar width (1.2 ± 1.3 mm), Bimaxillo-mandibular width (2.1 ± 2.3 mm) and the Maxillary width (2.5 ± 1.6 mm). The greatest change in the dental measurements was in the Maxillary first molar width (6.4 ± 0.1 mm). The Maxillary central incisor angle decreased significantly (-7.9 ± 8.4 mm), indicating an increase in the distance between the apices of the central incisors.

Conclusion
Volumetric 3-D CT scanning provides a useful method for assessing skeletal and dental changes after rapid maxillary expansion. Although significant increases occurred in most skeletal and dental measures, it appears that dental tipping explains most of the expansion.

Abstract
IoT networks are witnessing a rapid growth in various domains of our daily life, offering more attractive features in terms of measurement accuracy, easy implementation and affordable deployment costs. This outstanding boom is not undoubtedly far away from different challenging issues that impede the network efficiency and quality. The security concern remains one among the prominent issues that affect both the edge and the core IoT network where risks increase in conjunction with the network expansion. RPL is the well-known routing protocol for the edge part of the IoT network, intended to meet the requirements of the constrained IoT devices. Despite its various advantages, RPL remains suffering from various security attacks targeting the topology, the traffic, and the nodes resources. Our work presents a new silent decreased rank attack against RPL-Contiki, as well as a lightweight countermeasure. The obtained results on a random studied topology show that almost half the existing nodes in the topology were attracted by the planted malicious node, through its falsified low rank. Moreover, an increase of 12.5% in the control overhead and an increase of 15% in the total consumed energy are recorded compared to the attack-free topology. On the other hand, the attack did not heavily affect the PDR, but the latency showed an increase of 45% compared to the attack free case. This damaging effect makes this modified rank attack a serious threat to IoT RPL based networks.

Authors: Çelik Türkan 
Published: December 2023

Abstract
The present study aims to examine prospective history teachers’ process of using digital games to design history lessons and delivering the designed lessons in virtual classrooms. The study employed a design-based research model and was conducted with 31 participants selected based on the criterion sampling method. Data were collected through design documents, interview forms, and video recordings and were analyzed using descriptive and content analysis techniques. During the process, participants were able to design history lessons with digital games and deliver the designed lessons in virtual classrooms. Analysis of participants’ views on the process led to the emergence of the following themes: “The Problems Emerging in the Process,” “The Pedagogical Effects of the Process,” “The Technological Effects of the Process,” “The Effects of the Process on Reflective Thinking,” “The Effects of the Process on Participants’ Thoughts about Virtual Learning Settings,” and “The Effects of the Process on Participants’ Thoughts about the Researcher.” The study results show that despite some problems with the use of technology, the process had a positive effect on the participants. In this regard, future studies may be recommended to focus on prospective teachers’ competencies in using technology effectively when teaching lessons in virtual learning environments.
Analysis of Current State of Alternative Propulsion in a Sector of Passenger Railway Transport
Authors: Pribula Daniel , Kendra Martin 
Published: December 2023

Abstract
Green railway transport (RT) is not always a completely green transport solution, as there are still many nonelectrified or partially electrified lines in operation with polluting engine traction. Although electric rail is the most environmentally friendly, electrification of lines is a time-consuming and costly project, especially on less busy lines where electrification would be inefficient and unprofitable. Even though electric railway is the most environmentally friendly solution, electrification of lines is a time-consuming and expensive project, especially on less frequented lines where electrification would be inefficient and unprofitable. Alternative propulsion (AP) in RT is not only a way to reduce the operational emissions of passenger trains, but also to save energy and fuel, save time due to vehicle changes, and reduce the overall carbon footprint from transporting goods and people.
The aim of this paper is to examine in detail the current state of development and availability within the AP railway industry, specifically for passenger transport needs, and to transparently present the results in a simple and clear way. In addition, the paper explores the possibility of applying the alternatively powered system to the conditions of the H0 model railway and research with this model.

Authors: Da Silva Iranilton Trajano , Barbosa Maria de Fátima Nóbrega 
Published: December 2023

Objective: The objective of this article is to evaluate how the Procurador Romero Nóbrega Penitentiary, in Patos - PB, has internalized in its administration practices an integrated perspective of its ISO 14001 environmental management, ISO 9001 quality and OHSAS 18001 occupational health and safety systems.

Theoretical reference: An Integrated Management System (IMS) acts in the interconnection of other systems, aiming to achieve planned management of the execution of services in order to satisfy the internal and external needs of organizations, bringing together information and experiences from different areas in a single environment of work. This integration comprises a tool capable of discovering specific paths to be followed to achieve the desired objectives, in addition to creating an organizational culture of permanent or continuous improvement in its activities.

Method: As a methodology, a qualitative, exploratory and descriptive approach was used to understand how prison management occurs in terms of the incorporation of management systems.

Results and conclusion: The study showed that the penitentiary does not comply with the penal executive norm and, with regard to the management system models studied, the unit internally needs investment in its structure, in its human capital and, in the external context, more public policies to achieve sustainable management.

Implications of the research: The research is of great relevance to the prison system and the academic world, showing the possibility of making penal units sustainable, aggregating management systems and enhancing the achievement of prison sustainability.

Originality/value: Scientific production in Brazil on the implementation of sustainable prisons is incipient, therefore, the research seeks to contribute to helping gaps in the thematic literature, as well as drawing the State's attention to alternatives for the prison system by integrating systems with sustainability goals, respecting environmental, social, economic and human values.
Use of Pedotransfer Equations (PTF) to Estimate soil Density in the Hydrographic Basins of The Amambai, Iguatemi and Ivinhema Rivers in the State of Mato Grosso do Sul
Authors: Pimentel Letícia Guimarães , Teixeira Wenceslau Geraldes , Hernani Luís Carlos , Bhering Silvio Barge , Valle Lillyane Gomes de França 
Published: December 2023

Theoretical framework: Bulk density (Bd) is a physical property of soil used as an indicator of soil compaction, influencing root growth and density, water movement and retention in the soil, it is an essential characteristic for assessments of carbon stocks or other nutrients in the soil.

Objective: This studyevaluates the accuracy and selects pedotransfer functions (PTFs) for Bd estimates for soils in the Amambai, Iguatemi, and Ivinhema River basins in Mato Grosso do Sul - MS.

Method: Estimates of Bd values of the samples were made using eleven PTFs-Bd that were calibrated to estimate Bd for Brazilian soils. The accuracy of PTFs-Bd predictions is evaluated based on the lowers root mean square error (RMSE) and the highers coefficient of determination (R²).

Results and conclusion: Among the eleven analyzed PTFs-Bd, the most accurate ones were PTFs- Ds 1, 2, 3, and 4 by Huf dos Reis et al. (2024) and the one by Tomasella and Hodnett (1998). PTF-Bd 3, which uses fine and coarse sand and clay as predictors, showed the highest accuracy for the total dataset (88 samples). PTF-Bd 5 obtained better accuracy in estimating Bd in Latossolos Vermelhos, Argissolos Vermelho Amerelos, and Neossolos Quartzarênicos.

Research implications: Identifying the best PTFs for estimating Bd for the study area's soils will facilitate other research as carbon stocks estimation and use of hydrophysical PTFs that use Bd as predictor.

Originality/Value: PTFs for estimating Bd for soils in the state of MS have not yet been developed, highlighting the need to evaluate and indicate between existing PTFs the more accurate.
"Story Time!": Coping with Low-Motivated Students using Big Book
Authors: Ignatius Javier C. Tuerah  
Published: December 2023

Background:
Reading the picture book provides students with numerous positive effects, especially young students, such as attracting students' interest, boosting creativity, providing a pleasant, relaxed vibe, and creating fun and meaningful learning. This research seeks to investigate whether the reading comprehension of low-motivated students who are taught with the big book or with the daily storybook varies significantly.
Methodology:
This study used quasi-experiments, and each group received treatment eight times. The participants were 44 students recruited to become the sample of this study, consisting of experiment and control groups.
Findings:
This study revealed that students with low motivation who taught with Big Book as a platform are better than students with low motivation taught on traditional media. Several factors have made a big book an instrument that has a more significant impact on students' perception of reading than conventional media. Secondly, students engaged more in-class reading than in conventional media. Thirdly, the book sparked the interest of students and inspired them to learn more. Fourthly, the Big Book helped students create the meaning of the text and appreciate the text more thoroughly.
Conclusion:
English oral books such as Big-Book are more effective than traditional content in the second year. This study and published data support this conclusion that using large books as a tool for second years' reading understanding affects students' understanding of lectures significantly. The statistical study has found that the total student readership in the test group is higher than the average student score in the control group.
Keywords: reading comprehension; low motivation; pupils; picture book.

Hypertension or high blood pressure is a non-communicable disease most suffered elderly. It is characterized by increasing the pressure of blood vessels. Music therapy is one of non-pharmacological management on hypertension so it can be controlled to improve quality of life the patient.The study aimed to analyze the effect of religious music therapy on blood pressure changes in elderly with hypertension. The study design wasÂ quasy experiment with a pre-post test approach. Sample of 25 respondents was taken by purposive sampling and carried out at Unit Pelayanan Teknis (UPT) Pesanggrahan Penyandang Masalah Kesejahteraan Sosial (PMKS) Mojopahit Mojokerto. Data analyzed by paired T-test. The results showed a pre-test systolic mean of 156.12 mmHg and a post-test of 149.9 mmHg with a p value of systolic = 0.00 (p <0.05) and a pre-test mean diastolic of 95.76 mmHg and a post-test of 89.40 mmHg with a diastolic p value = 0.00 (p < 0.00). It means that was an effect of religious music therapy on reducing blood pressure in hypertensive elderly at UPT Pesanggrahan PMKS Mojopahit. When music therapy was heard, the brain will produce endorphins that relieves anxiety and tension, so it decrease blood pressure. The recommendation of this study was religious music therapy can be chosen as non-pharmacological management to control elderlyâ€™s blood pressure
