Authors: Behardien Nashreen , Brijlal Priscilla , Roman Nicolette Vanessa 
Published: June 2023

ObjectivesThe aim of the research was to evaluate the traditional exodontia block course. The objectives were to explore the experiences and views of students, clinical teachers and dental practitioners of the various elements of the course curriculum.MethodsThe study was a qualitative, participatory action research study using descriptive analysis. The study was conducted at a Dental Faculty in South Africa. A purposive sample of students, clinical teachers and dental practitioners were invited to participate. Focus group discussions were used to collect data which was analysed by an external coder.ResultsThe study population consisted of 15 undergraduate dentistry students, 10 clinical teachers and seven dental practitioners. Four broad themes with sub-themes emerged from the study. The main themes identified strengths and deficiencies of the traditional course and made recommendations for its improvement. The themes identified were i) Integration of knowledge and skills, ii) Block course structure, iii) Challenges associated, and iv) Recommendations for improvement. Overall, the participants were satisfied that the course met its objectives. The results pertaining to clinical skills acquisition identified that teaching the use of elevators and luxators in the course, and standardisation of terminology among all clinical teachers as areas requiring attention. Teaching and learning strategies such as community-based learning, peer learning, case reviews, feedback and visual technology were viewed by the student, as well as clinical teacher samples, as strategies most beneficial to clinical learning.ConclusionsThe review of the curriculum for exodontia skills acquisition and development, provided several benefits. Firstly, this research served as a quality assurance indicator. It further highlighted many teaching and learning strategies that would improve clinical skills development, reduce stress and anxiety, and support student learning. To a large extent, pertinent information was obtained that served to inform the subsequent redesigning of the course. The findings of the study augment the literature currently available on the best practice for exodontia skills acquisition and development and provide baseline information for the planning and redesign of related courses.

Sayung Subdistrict is part of Demak Regency which is located in the northern-coastal region has experienced tidal floods with vulnerable socio-economic in decades. This study aims to determine the level of community vulnerability and the effectiveness of the community adaptation strategy in dealing with the tidal flood. Meanwhile, quantitative and qualitative approaches are used to explore people's adaptations and vulnerability. By used a random sampling technique, people in the Siwulan Village, Bedono Village, Timbulsloko Village and Surodadi Village was choosen as the research's population. The variables are: community's vulnerability (physical, economic, social and cultural); and adaptation strategies. Questionnaires, observations and documentation has been done for data collecting. The Livelihood Vunerability Index (LVI) is used to measure and analyze the variables by using a score-calculation with 4 criteria including very-effective, effective, less-effective, ineffective. Based on the data, structural adaptations, including road dredging, embankment construction and raise floor elevation are considered effective to very effective. While raising household furniture was considered effective to very-effective by the people of Bedono Village, Timbulsloko Village and Surodadi Village, while the Sriwulan Village community considered the structural adaptation to be less effective if it was not accompanied by the elevation of the building floor.
Biomechanical effects of inclined implant shoulder design in all-on-four treatment concept: a three-dimensional finite element analysis
Authors: Aktas Taha , Diker Nurettin 
Published: June 2023

Abstract

Objectives
The aim of the present study was to assess the biomechanical behaviour of using a posterior implant design with inclined shoulder designs in all-on-four treatment via three-dimensional finite element analysis.

Methods
Implants with standard and inclined shoulder designs were modelled for posterior implants. Implants were positioned into the maxilla and mandible models according to the all-on-four concept. Compressive stresses in the peri-implant bone, the von Mises stresses in the different components of the prosthetic restoration, and movement of the prosthesis were obtained.

Results
The compressive stresses of the models with inclined shoulder design resulted in 15–58 % decrease compared with standard shoulder design. The von Mises stresses in the posterior implants reduced 18–47 %, stresses in the implant body increased 38–78 %, stresses in the abutment screw reduced 20–65 %, stresses in the framework of prosthesis reduced 1–18 % and deformation of the prosthesis was reduced 6–37 % in the models of inclined shoulder design compared with models of standard shoulder design. The compressive and von Mises stresses were generally higher in the mandible models than in the maxilla models for standard and inclined shoulder designs.

Conclusions
All evaluated components of the simulated treatment except for posterior abutment bodies showed better biomechanical behaviour with inclined shoulder design. The clinical success of all-on-four treatment maybe enhanced by using posterior implants with an inclined shoulder design.
Assessment Literacy: Changing Cultures, Enculturing Change in Hong Kong
Authors: Davison Chris 
Published: June 2023

Abstract
Teacher assessment literacy has gained significant attention in recent years due to its critical role in learning and teaching. Various theoretical and empirical conceptualizations of this construct have been emerging with more recent emphasis on building teachers’ knowledge and skills. The aim is to make highly contextualized, fair, consistent and trustworthy assessment decisions to inform learning and teaching to effectively support both student and teacher learning. This article explores changes in secondary English language teachers’ assessment literacy following the introduction of school-based assessment for learning as part of high stakes secondary school assessment reform in Hong Kong. Drawing on teacher questionnaires completed by almost 4,500 teachers who undertook a common professional development course conducted over the first six years of assessment reform (2005 – 2011), this paper explores the impact of professional development on teachers’ assessment literacy. Despite Hong Kong’s deeply ingrained competitive examination-oriented culture, an analysis of the quantitative and qualitative data from pre- and post-program evaluations demonstrate signs of positive change in teacher attitudes, confidence and practices, in particular in using assessment criteria, designing and implementing appropriate assessment tasks, involving learners more actively in the assessment process, making trustworthy assessment decisions and providing effective feedback and feed-forward to students to improve student learning. The findings of the study suggest that changes in assessment culture are possible, provided teachers are well supported. The implications for assessment reform and for the development of teacher assessment literacy more generally are also discussed.

Published: June 2023

Abstract
The demand for lightweight materials (aluminium and magnesium alloy) in structural applications is increasing due to strength ratio, corrosion resistance, formability, and recyclability. Fusion welding of aluminium and its alloy is difficult due to the formation of hot cracking, alloy segregation, porosity, etc. Henceforth, fusion welding is not an ideal process for joining aluminium and its alloy. Steel rivets are being used to join similar and dissimilar alloys in different joint configurations. Since the use of steel rivets, aircraft weight has increased drastically. Although, dissimilar metal corrosion has been encountered. These two are the main problems in structural fabrication industries. The solid-state welding friction stir welding process eliminates the issues mentioned earlier. This process can weld materials well below the melting point. Moreover, the formation of weld in the weld line could be achieved by severe plastic deformation and recrystallized grains. This metallurgical joint may replace the rivets.

Abstract

Objectives
Transforming growth factor-beta (TGFβ1) is involved in tumorigenesis and metastasis. It provides this effect both by disrupting the thiol-disulfide balance and through the cancer-upregulated gene (CUG2) and transforming growth factor beta-induced (TGFBI) genes in the signaling pathway. In this study, the roles of TGFβ1 and related genes, as well as thiol-disulfide balance, in the formation of prostate cancer and metastasis were investigated.

Methods
Tissue samples were taken from 33 benign prostatic hyperplasia (BPH) and 35 prostate cancer (PC) patients to determine the Gleason score and metastasis. TGFβ1, CUG2, and TGFBI gene expression levels were measured by RT-PCR. Serum prostate specific antigen (PSA) levels were measured in patients, and PSA density (PSAD) was calculated. Total thiol and native thiol measurements in serum were performed spectrophotometrically, and disulfide was calculated.

Results
In patients with prostate cancer and metastases, PSA and PSAD levels were high, while total thiol and native thiol were significantly lower (p<0.05). TGFβ1, CUG2 and TGFBI gene expression levels were higher in patients with prostate cancer and metastases and were negatively correlated with total thiol and native thiol (p<0.001).

Conclusions
As a result of our study, we determined that the increase in TGFβ1, CUG 2 and TGFBI in prostate cancer plays an important role in cancer formation and metastasis by disrupting the thiol-disulfide balance.

Published: June 2023

Abstract
A simple and direct determination method for protein on fabric by measuring the surface reflectance of the bicinchoninic acid (BCA) reaction color has been reported. This study investigated the effects of four synthetic surfactants, six sodium fatty acids and one enzyme, as the coexisting substance on the direct determination of protein in cotton fabrics. The influence of the coexisting substance to the BCA reagent was examined. Then, seven coexisting substances present in detergents were selected, and the reflectance of reacted test swatch by protein and each coexisting substances were also measured, and then compared to the values obtained for protein alone. With the exception of sodium dodecyl sulfate and lauric acid, the concentration of the surfactants used in this study had little effect on protein determination. At low protease concentration there were no significant effects on the BCA method and determination.

Published: June 2023

AbstractExperiments that take advantage of head-fixed behavioral tasks have been a staple of systems neuroscience research for half a century. More recently, rodents came to the forefront of these efforts, primarily because of the rich experimental possibilities afforded by modern genetic tools. There is, however, a considerable barrier to entering this field, requiring expertise in engineering, hardware and software development, and significant time and financial commitment. Here, we present a comprehensive, open-source hardware and software solution to implement a head-fixed environment for rodent behaviors (HERBs). Our solution provides access to three frequently used experimental frameworks (two-alternative forced choice, Go-NoGo, or passive sensory stimulus presentation) in a single package. The required hardware can be built at a relatively low cost compared with commercially available solutions, from off-the-shelf components. Our graphical user interface-based software provides great experimental flexibility and requires no programming experience for either installation or use. Furthermore, an HERBs takes advantage of motorized components that allow the precise, temporal separation of behavioral phases (stimulus presentation, delays, response window and reward). Overall, we present a solution that will allow laboratories to join the growing community of systems neuroscience research at a substantially lower cost of entry.
Neural Evidence for Boundary Updating as the Source of the Repulsive Bias in Classification
Authors: Lee Heeseung , Lee Hyang-Jung , Choe Kyoung Whan , Lee Sang-Hun 
Published: June 2023

Binary classification, an act of sorting items into two classes by setting a boundary, is biased by recent history. One common form of such bias is repulsive bias, a tendency to sort an item into the class opposite to its preceding items. Sensory-adaptation and boundary-updating are considered as two contending sources of the repulsive bias, yet no neural support has been provided for either source. Here, we explored human brains of both men and women, using functional magnetic resonance imaging (fMRI), to find such support by relating the brain signals of sensory-adaptation and boundary-updating to human classification behavior. We found that the stimulus-encoding signal in the early visual cortex adapted to previous stimuli, yet its adaptation-related changes were dissociated from current choices. Contrastingly, the boundary-representing signals in the inferior-parietal and superior-temporal cortices shifted to previous stimuli and covaried with current choices. Our exploration points to boundary-updating, rather than sensory-adaptation, as the origin of the repulsive bias in binary classification.SIGNIFICANCE STATEMENTMany animal and human studies on perceptual decision-making have reported an intriguing history effect called “repulsive bias,” a tendency to classify an item as the opposite class of its previous item. Regarding the origin of repulsive bias, two contending ideas have been proposed: “bias in stimulus representation because of sensory adaptation” versus “bias in class-boundary setting because of belief updating.” By conducting model-based neuroimaging experiments, we verified their predictions about which brain signal should contribute to the trial-to-trial variability in choice behavior. We found that the brain signal of class boundary, but not stimulus representation, contributed to the choice variability associated with repulsive bias. Our study provides the first neural evidence supporting the boundary-based hypothesis of repulsive bias.
