Analysing Interaction in Science Classrooms
Authors: Danielsson Kristina , Bergh Nestlog Ewa , Jeppsson Fredrik , Tang Kok-Sing 
Published: February 2023

One central issue for research in classrooms is to provide insights concerning characteristics of classroom interaction that can help teachers improve their teaching. In the present study, we analyse spoken interaction in one elementary physics classroom by the use of two different frameworks, targeting similar aspects of social communication, namely how discourse patterns shape the relations between participants. The two frameworks utilized are on the one hand analyses of the communicative approach according to Mortimer and Scott, combined with analyses of discourse patterns such as IRE-patterns, and on the other hand analyses related to the interpersonal meta-function in Halliday’s systemic-functional grammar, SFG. The aim was to highlight possibilities and limitations of the different frameworks.
Our analyses reveal that the two analytical frameworks have partly the same, partly different affordances concerning what they can reveal about classroom interaction. The analyses of the communicative approaches have the potential of elucidating discursive patterns and power relations at a general level, while the analyses based on SFG can provide more details about the power relations in terms of how the participants actually structure their utterances. The results are also discussed regarding implications for education.
THE STIGMA OF INDONESIAN SOCIETY ON COVID-19 PATIENTS AND HEALTH WORKERS BASED ON THE HEALTH BELIEF MODEL THEORY
Authors: Aprianti Aprianti 
Published: February 2023

The number of covid-19 cases in Indonesia has increased significantly. So, the government recommend physical distancing. As a new disease, the policy caused the public worry. This triggers the community to give social stigma to Covid-19 sufferers and health workers. This research is a quantitative study with a cross sectional method. The Indonesian population aged 15 - 44 years, have access to the internet, not health workers, not students in health schools andÂ willing to be respondents. The number of samples was 360 respondents. Bivariate data analysis used chi square test and multivariate using logistic regression. As many as 63.6% of respondents did not know their Covid status. Respondents gave a stigma of 50.8%. The variables related to the stigma given by the community to health workers and Covid-19 patients were perception of severity (p value = 0.037), self-efficacy (p value = 0.016) and perceived threat (p value = 0.001). The variable with the most dominant relationship is perceived threat with the value of Exp (B) = 3, 834. It is hoped that the need for education from health workers to the community about the covid-19 virus and how to overcome it so that people do not feel threatened and give stigma.

Multigene Genetic Programming Based Prediction of Concrete Fracture Parameters of Unnotched Specimens
Authors: Sudhir M. R. , Beulah M. 
Published: February 2023

This study explores the fracture energy of notched and unnotched concrete specimens subjected to the classical three-point bend test, instantiating a gradational step in the continued development of concrete fracture mechanics. An experimental campaign involving 18 notched test specimens and nine unnotched specimens of three different grades of concrete, an examination of the existing literature models for unnotched specimens, and a novel Multigene Genetic programming (MGGP) based concrete fracture energy model for unnotched specimens are integral to this study. As a salient result, the multiple approaches to quasi-brittle materials adopted in the study, highlighted the criticality of the determination of fracture energy, tensile strength and characteristic length for the crack width study. The failure modes of notched and unnotched specimens were found to be similar. The reported literature has mainly focused on a limited number of fracture energy influencing parameters. Therefore, six impact parameters have been chosen and incorporated into the present study to provide a more acceptable explanation of concrete fracture behaviour. A sensitivity analysis of the parameters and an error analysis of the model undertaken have established the accuracy and robustness of the developed MGGP model.

Contribution to Railway Track Maintenance Planning from the Analysis of Dynamic Movements of Trains
Authors: Seraco Isaias Pereira , Ratton Neto Hostilio Xavier 
Published: February 2023

Dynamic movements of trains in relation to the track have a significant impact on the displacement stability of rail vehicles, having effects inclusive of operational safety. Although there are numerous approaches to track maintenance planning, most of them are based solely on long-term geometric degradation assessments without taking into account any dynamic parameters in assessing operational safety or establishing means to predict future rolling stock accelerations relative to the track in order to develop safer maintenance plans. This paper introduces a method of track maintenance planning based on geometric degradation modeling and prediction of rolling stock vertical and horizontal acceleration. The goal is to establish how frequent geometric maintenance is necessary to ensure operational safety under geometric and dynamic criteria. This approach is based on regression models defined from geometric and dynamic inspection data. The method was applied in a passenger railway and obtained expressive results that corroborated the need of considering dynamic aspects on maintenance planning, as sections of the analyzed railway were identified with operation becoming unsafe, under the dynamic criterion, before the geometric safety tolerances are reached. This work is intended not only to propose a planning method but also to present to the scientific and technical communities a novel approach to be explored and developed in future research. The obtained results, therefore, do more than confirm quantitatively the relevance of this analysis; they also demonstrate qualitatively how promising the development of this thematic field is. In this regard, this work also presents in its conclusions some research opportunities to be explored for the development of this theme. Doi: 10.28991/CEJ-2023-09-02-02 Full Text: PDF

Bruner dan David Ausubel sama sama tokoh dalam toeri belajar kognitif namun mereka memiliki pemikiran yang berbeda terkait pencapaian belajar. Menurut Bruner, manusia adalah sebagai pemroses, pemikir, dan pencipta informasi. Oleh karenanya, yang terpenting dalam belajar adalah cara-cara bagaimana seseorang memilih, mempertahankan, dan mentransformasikan informasi yang diterimanya secara aktif. Sedangkan dari sudut pandang David Ausubel memiliki pendapat yang bertentangan dengan Bruner, menurut Ausubel, pada dasarnya orang memperoleh pengetahuan melalui penerimaan, bukan melalui penemuan. Konsep-konsep, prinsip, n ide-ide yang disajikan pada siswa akan diterima oleh siswa. Dapat juga konsep ini ditemukan sendiri oleh siswa.

Toward interpretation of the term transformation in architecture
Authors: Gatin T. N. 
Published: February 2023

Purpose: The aim of this work is to study different interpretations of the term transformation in architecture and define the term transformable architecture.Methodology: The thesaurus method and comparative analysis. Data comparison allows to define and structure the conceptual apparatus. Works of A.A. Gaiduchenya, N.A. Saprykina, R. Kronenberg, J.D. Lee, R. Reuter are studied and analyzed. These researchers define the transformable architecture and created their own systems of definition of changeable architecture.Research findings: Analysis concerning the interpretation of the term transformation in architecture show four possible notions. It is concerned if architecture is the intangible system of knowledge or artificial object of material world, and transformation is considered as the process of changing via evolutional processes or the ability to change. Structure of notions helps to define original term of transformable architecture.Practical implications: This work highlights the concept uncertainty of variable architecture and complex search for materials in the field.Originality: The term transformation is ambiguous in architectural science. This word is used starting from the evolutional change in architecture and ending by specific techniques of controllable change of space embedded in its architecture at the design stage. The versatility of the term transformation and words with similar roots, creates many interpretations by different researchers.
Conical drill bit for optimized external ventricular drain placement: a proof-of-concept study
Authors: Ravina Kristine , Yang Natalia , Brocoum Sophia , Pasco-Anderson Julia , Walker Robert L. , Khan Marina , Cabodi Mario , Holsapple James 
Published: February 2023

OBJECTIVE
Despite external ventricular drain (EVD) procedures being commonplace in neurosurgical practice, suboptimal placement rates remain high, and complications are not uncommon. The angle of the EVD catheter insertion and the accuracy of the drill hole placement are major factors determining successful EVD placement that are dependent on the drill bit morphology. The standard cylindrical 2-fluted twist drill bit creates a relatively deep and narrow drill hole that requires precise positioning, has limited visibility of the drill hole bottom and restricted catheter angular adjustment range, and poses the risk of inadvertent dural puncture. To overcome the standard problems associated with EVD drill bit morphology, the authors propose novel cone-shaped drill bits for EVD placement.

METHODS
Conical drill bits of 30° and 45° were designed, manufactured, and tested in a simulated laboratory setting as well as in three human cadavers with intact skull, dura mater, and brain. Drill bit performance was rated by neurosurgical trainees across various domains using Likert scale–type questions.

RESULTS
In the laboratory, maximum drilling temperatures adjacent to the drill hole were recorded and compared for the standard drill bit and the 30° and 45° conical drill bits and were not significantly different (p = 0.631 and p = 0.326, respectively). The maximum temperature recorded directly underneath the drilling site for the 45° drill bit was significantly higher than the temperature of the standard drill bit (p = 0.043). The differences between the standard and 30° drill bits were not significant (p = 0.783). Upon cadaver testing, the drilling times with 30° and 45° conical drill bits were significantly longer than those with the standard drill bit (p = 0.036 and p = 0.002, respectively). Likert scale scores were significantly higher for the conical 30° (median [IQR] 4.7 [3.3–5]) and 45° (4 [2–5]) drill bits than for the standard drill bit (1.7 [1–2.5], p < 0.0001), indicating significantly better performance. Conical drill bits used as a "rescue" strategy allowed for an EVD catheter angular adjustment range 6 to 9 times greater than that for the standard drill bit and resulted in a zero inadvertent dural puncture rate.

CONCLUSIONS
The 30° conical drill bit can be safely used on its own or as a rescue tool to potentially achieve improved confidence, visualization, targeting, and precision of EVD placement while essentially eliminating the possibility of unintentional dural puncture with minimal increase in the total procedure time.
