ICPE 2022 Special Edition - Editorial
Authors: Wegener Margaret
Published: October 2024

This special issue, in multiple parts, celebrates The International Conference on Physics Education which was held online in late 2022. Its theme was Physics Education: Preparing for the future.
In this first part of the special issue, international contributions include Brazil, Czech Republic, Germany, Mexico and U.S.A. This set of papers showcases diverse approaches to physics education studies, from varied perspectives. Investigations include local interventions and reflections, surveys involving hundreds of participants, nationwide audits, and statistically-assisted searching for causal links.
A common theme of the papers is ‘thinking and feeling’. How a student engages with physics, and ultimately their success doing physics, is partly determined by whether they self-identify as a ‘physics person’, and by their beliefs about their capability to learn physics. Li and Singh explore relationships between factors that affect physics identity in university students; Goldhorn et al aim to train a physics-specific growth mindset in school students. Developing capability is also the focus of Salazar et al, who have designed a strategy to develop skills in critical thinking and problem-solving in engineering students. Such skills and a positive mindset are highly valuable when facing the inevitable challenges of study and careers.
Multiple authors acknowledge perceptions of difficulty as problematic for physics students and instructors. Aiming to connect to the real world of learners, making physics more meaningful, is a strategy to engage students which is discussed in multiple papers. Holubova offers a learning module that relates thermal physics to the achievement of comfortable, energy-efficient buildings for the students’ local environment, after having identified high-school curriculum topics that are the most difficult to teach and learn. Fagerstrom argues for the inclusion of medical physics topics in introductory-to intermediate physics for a range of students, and discusses suitable examples.
How humans relate to our universe is a basic spark of connection to physics in many societies. Dos Santos and Nardi contend that emerging research in cultural astronomy has implications for training teachers, in encouraging education that respects cultural differences.
Collectively, this group of papers analyses the existing educational situation and contributes strategies to positively affect physics learning outcomes – helping individuals feel that physics is a place for them, and instilling beneficial ways of thinking within the physics space.
Thank-you for the efforts of all the authors and reviewers, and the organisers of the conference that inspired these papers.
I hope you find this collection of articles stimulates your own thinking about the future of physics education.

This study is longitudinal; data were collected from admission to course completion with the goal of understanding the impact of the pedagogical project and course structure. The Pecheutian Discourse Analysis provided theoretical and methodological support for the development of this research. The analysis of the interviews and questionnaires revealed that the course’s pedagogical project and curricular structure play an important role in the changes in the conceptions of future Physics teachers and the construction of their teaching identity.
Analysis of Kinematics Graph Interpretation Skills Using RapidMiner
Authors: Intakaew Kanokporn , Wattanakasiwich Pornrat
Published: October 2024

This study explores the application of data mining techniques in physics education research, focusing on the analysis of kinematics graph interpretation skills. The research had two main objectives: to demonstrate the utility of RapidMiner, a data mining tool, in analyzing educational data, and to compare its effectiveness with traditional item analysis methods. Fifty-nine Grade-10 students at Chiang Mai University Demonstration School completed the Test of Understanding Graphs in Kinematics (TUG-K) before and after participating in a problem-based learning module integrating high-speed video analysis. Traditional statistical analysis revealed significant improvement in student performance (p<0.001, effect size 0.76). Association rule mining, conducted using RapidMiner, uncovered key relationships between test items that were not apparent through traditional analysis. These relationships provided insights into common student misconceptions and areas requiring targeted instruction. The study demonstrates the potential of advanced data mining techniques to reveal deeper patterns in educational data compared to conventional item analysis methods. This novel application of RapidMiner in physics education research offers a promising approach for more detailed analysis of student understanding, potentially informing more effective teaching strategies and curriculum design in physics education.

Published: October 2024

Success in higher education is associated with both students’ capacity for self-regulation and the ability to understand assessment processes. The Assessment Literacy Module (ALM) is an interactive online tool designed to promote development of students’ own academic judgement and assessment literacy. Students act as assessors of work samples; they use the assessment rubric and are guided by expert marker feedback that relates the marking standards to the assessment outcome. In this study, we evaluated perceptions of ALM impact on the student learning experience by surveying staff (N = 18) and students (N = 416) involved in 18 undergraduate subjects. Students reported that after completing the ALM they had a better understanding of the assessment criteria (94%); they felt the module helped them prepare for their assessments (90%) and were more confident about their assessment quality (86%). Staff perceptions of the benefits of the ALM closely aligned with those reported by students. We recommend this tool for enhancing assessment literacy and developing academic judgement in undergraduate students of all levels. The ALM is of greatest utility in large cohort subjects as a sustainable approach for providing all students access to expert feedback. Future research will explore how the ALM benefits teaching practices.

Published: October 2024

This research analyses the perspectives of all key stakeholders in an agricultural industry school partnership (ISP), including industry partners, which are rarely identified in the literature. Understanding this range of perspectives provides people who deliver and participate in ISPs with a greater understanding of how to deliver quality partnerships that benefit students, educators, and the agricultural industry. This research aimed to explore the nature of one agricultural ISP in Gippsland, Australia, by understanding the structure, key principles identified by participants, and how the outputs met the teacher and industry partners’ objectives. A qualitative case study utilising surveys and semi-structured interviews with the teacher and three industry participants, semi-structured interviews with the Principal, an education department employee and industry managers, and pre- and post-surveys with students, were used to collect data for this narrative analysis. The findings demonstrate that the ISP has a complex ecological structure. Key principles identified by participants included having a facilitator, clear communication and collaboration, funding, the ISP being engaging and flexible, acknowledging industry partners, and reinforcing the learnings. Teacher and industry participants’ objectives were met, including: increasing student and teacher knowledge of agriculture, and for one industry partner, knowledge of how to deliver relevant content.

In recent years,e-commerce systems have expanded and been used by a variety of businesses. The e-commerce system is an online platform for selling and promoting products to customers. Customer segmentation is a technique of putting customers into groups based on shared traits. The purpose of customer segmentation is to determine a company's target market's purchasing habits, identify trends among various customer segments, and assess customer loyalty. This information helps the business develop targeted marketing campaigns that increase the number of profitable and devoted customers it serves. It is more challenging to secure a customer base in the age of globalization and digitization since consumers have been given many options for making purchases. While obtaining clients is the key objective of any firm, the results of this study will assist the organization in developing a range of research criteria to determine the strategies it uses for marketing. Certain unsupervised machine learning techniques were employed in this study to examine customer data. Clusters develop in unsupervised machine learning methods. This business must concentrate and dedicate all its resources to providing superior customer service to its consumers. In this paper, we have employed the technique of principal component analysis (PCA) for dimensionality reduction and k-means, agglomerative, DBSCAN to determine the customer's segment. The findings of this study are that k-means algorithms gave a 0.41 silhouette score when they clustered into 5 clusters, the agglomerative algorithms gave a 0.4 silhouette score when they clustered into 4 clusters, and DBSCAN algorithms gave a 0.44 silhouette score when they clustered into 2 clusters. The best model based on the performance is k-means.

Published: October 2024

One of the most common cancer affects women are the Breast Cancer. These are predicted using the diagnosing methodologies. The CT scans are the most common screening mechanisms is the computer aided prediction mechanism. Still, based on the reasons of genetic information, the microarray data is applied as the solution for diagnosing the cancer cells. Dealing with the microarray data it has various consequences, from those consequences one of them is its high dimensionality. The primary intention of this approach is to introduce an ensemble model to diagnose the cancer cells fromthe dataset. Initially, Adaptive Guided Bilateral Filter (AGBF) is applied to denoise the input images and to filter the images by sharpening them. Afterwards, to segment the images by the conversion of RGB images into grey levels the threshold mechanism is used. Minimum Redundancy Maximum Relevance (MRMR) feature inclusion and Local Search Adaptive Beta Hill Climbing (ABHC) are two hybrid feature selection approaches used in this article where the features and its importance were stored on a dataset. Then the diagnosing of the breast cancer is done by obtaining the majority voting ensemble classifier. The proposed approach is evaluated using a Breast Cancer Histopathological Image Classification (BreakHis) dataset and achieves the classification accuracy of 99.51%.

Published: October 2024

Ergonomic risk assessment tools are tools that have been designed to solve the problem of ergonomics in the workplace from manual material handling activities. The objective of this study is to investigate Musculoskeletal Discomfort among workers related to manual handling activities using Cornell Musculoskeletal Discomfort Questionnaires (CMDQ); to assess an ergonomics risk factor among workers related to manual handling activities using Manual Handling Assessment Chart (MAC), NIOSH Lifting Equation(NLE), and Key Indicator Method for Manual Handling Operation (KIM-MHO) method and; to compare the results between CMDQ and assessment tools. This case study was conducted in Parit Raja, Johor, Malaysia involving 34 male mechanics workers. The tools used are as stated in the objective with the help of measurement tools such as a goniometer. The result of the CMDQ reveals that the body part with the highest discomfort level among the workers in the lower back, shoulder right and shoulder left with the percentage from the total discomfort score of 20.91%, 13.57%, and 13.36% respectively. From the result of the assessments, it is concluded that the highest risk factor contributing to the MSDs is the bad posture of the worker during the manual handling operation followed by the frequency of lifting and the weight of the load. By comparing assessment tools, the first comparison is made between the CMDQ versus KIM-MHO, MAC Tools and NLE. In this comparison that, it is highlighted the result type from CMDQ are different from the KIM-MHO, MAC Tools and NLE as its questionnaire result shows us the discomforts levels on the body of workers and the body parts affected on their body for the last seven days but the assessment tools results show us the risk factor that contributes to the MSDs. For the comparison between the three assessment tools, it can be said that the tools that have the highest correlation with CMDQ are MAC Tools. In conclusion, most workers suffer from MSDs in their lower back due to their bad posture during manual handling. KIM-MHO is the best assessment tool among the three as it has the highest significance value while being the easiest tool to be used.

Published: October 2024

Bearing fault diagnosis plays a pivotal role in the realm of condition-based maintenance, with vibration spectra analysis standing out as a highly effective method for discerning issues in rotating machinery. Various signal processing tools, including wavelet analysis, empirical mode decomposition, and Hilbert-Huang transform, have been employed to scrutinize vibration spectra. However, these methodologies often necessitate human expertise to ensure optimal outcomes. In the pursuit of automated fault diagnosis, machine learning tools such as Artificial Neural Networks (ANN) and support vector machines (SVM) have emerged as viable alternatives. Over recent decades, considerable research efforts have been devoted to exploring the viability of employing Artificial Neural Networks (ANN) for automatic fault diagnosis, resulting in predominantly positive findings. Nevertheless, the accuracy of Artificial Neural Networks (ANN) is intricately linked to factors such as the neural network structure, encompassing considerations like the number of nodes, hidden layers, and the choice of activation function. Addressing this challenge, the present study introduces an innovative hybrid algorithm for automated bearing fault diagnosis, integrating Artificial Neural Networks (ANN) with the Bayes’ Theorem (BT) theory. The hybrid algorithm exploits Bayes’ Theorem (BT) theory to augment fault diagnosis results derived from Artificial Neural Networks (ANN), specifically by alleviating conflicting outcomes generated within the neural network. The study focuses on characterizing four conditions of bearings, namely a healthy state and three distinct fault types: rolling element, inner race, and outer race faults. Through the proposed hybrid algorithm, working in tandem with artificial neural networks, a demonstrated superiority is established, surpassing the results obtained by Artificial Neural Networks (ANN) in isolation. This pioneering approach not only underscores the potential for heightened accuracy but also underscores the enhanced reliability achievable in automated bearing fault diagnosis.

Do the Effects Persist? An Examination of Long-Term Effects After Students Leave Turnaround Schools
Authors: Pham Lam D. , Corcoran Sean P. , Henry Gary T. , Zimmer Ron
Published: October 2024

Whole-school reforms have received widespread attention, but a critical limitation of the current literature is the lack of evidence around whether these extensive and costly interventions improve students’ long-term outcomes after they leave reform schools. Leveraging Tennessee’s statewide turnaround reforms, we use difference-in-differences models to estimate the effect of attending a turnaround middle school on student outcomes in high school, including test scores, attendance, chronic absenteeism, disciplinary actions, drop out, and high school graduation. We find little evidence to support improved long-run student outcomes—mostly null effects that are nearly zero in magnitude. Our results contribute to a broad call for educational researchers to examine whether school reforms meaningfully affect student outcomes beyond short-term improvements in test scores.

Authors: Mazzuferi V. , Ingaramo P. , Joseau J.
Published: October 2024

El objetivo de este trabajo fue evaluar una metodología que permita, en una única etapa y mediante el uso del calor, controlar los insectos que infestan las semillas y disminuir el contenido de humedad para facilitar la trilla y favorecer el almacenamiento de las semillas, sin afectar el poder germinativo ni el vigor.
El tratamiento consistió en someter los frutos a aumentos paulatinos de temperatura cada 48 horas, de acuerdo con el siguiente régimen: 40°, 50° y 60°C, en estufa de aire forzado. Luego de la trilla, las semillas obtenidas fueron separadas, bajo lupa binocular, en sanas e infestadas. Las primeras se destinaron a las pruebas de germinación y envejecimiento acelerado, y las segundas se colocaron en cámara de cría a 25°C durante 7 meses. Del análisis de los resultados surge que el tratamiento produce un retraso en la emergencia y/o reduce notablemente las poblaciones de brúquidos que infestan las semillas de Prosopis. Además, disminuye el contenido de humedad, lo que facilita la trilla y favorece la conservación de las semillas. En las pruebas de germinación y envejecimiento acelerado se observaron diferencias estadísticas significativas (P ≤ 0,05) entre las semillas tratadas y el testigo.

Authors: Zorzoli R. , Mroginski L. A. , Picardi L. A.
Published: October 2024

Con la finalidad de evaluar diferentes condiciones culturales para la producción de callos y la posterior regeneración, se analizaron 4 genotipos de Lycopersicon esculentum: Planeuco INTA (P2), Rossol Selección La Consulta (R), Cal J (C) y Raci 53 (R2), en dos condiciones: luz y oscuridad. Como explanto se utilizaron folíolos. El medio basal para la producción de callos fue el MS, con diferentes concentraciones de reguladores vegetales: ANA 2 mg·L⁻¹ + BAP 1 mg·L⁻¹ (MI) y ANA 1 mg·L⁻¹ + BAP 0,5 mg·L⁻¹ (MII). Los medios de regeneración tuvieron la misma base salina, pero diferentes concentraciones de reguladores vegetales: BAP 2,25 mg·L⁻¹ + AIA 0,175 mg·L⁻¹ (MA) y BAP 4,5 mg·L⁻¹ + AIA 0,175 mg·L⁻¹ (MB). A los 30 días de la siembra in vitro se evaluó el porcentaje de callos (C). El explanto desdiferenciado se rediferenció en bajo porcentaje, y esto dependió de las condiciones previas a las cuales fueron sometidos los explantos. Estos resultados permiten concluir que la inducción de organogénesis a partir de tejidos indiferenciados en las condiciones culturales probadas no permitió desarrollar un protocolo de selección in vitro de mutantes.
Capitalismo, Medio y Ambiente, Desigualdad y Salud

Published: October 2024

Abstract This work states that beyond the cyclic crisis of capitalism, the system itself is in crisis, since the logic of creating greater wealth has exceeded the conditions of tolerance of the reproductive capacity of the environment, to limits not permitted for human welfare. On the other hand, this economic system that determines the relationships among production factors, settling the maximization of earnings and the minimization of costs, does not solve the world’s inequalities as regards wealth distribution. In fact, 80% of the poorest population does not reach the 20% distribution of incomes and the richest 0.02% keep 20% of it. Results also show that inequality also generates greater child mortality and mortality due to communicable diseases.
Dislipemias en Pacientes VIH

Published: October 2024

Abstract Since the introduction of highly active antiretroviral therapy (ART) in the treatment of HIV/AIDS patients, we have observed a change in the development of the disease, becoming a chronic therapeutically containable condition. The increase in survival goes together with associated diseases; cardiovascular ones have become relevant, being earlier and more severe. Dyslipidemias have a leading role in this pathology. In this work, we analyze their incidence and characteristics in HIV patients, with and without ART treatment. Lipid profile was different in the pre-treatment stage (low HDL, low total Cholesterol and normal TG) from the stage under ART (marked increase of TG and to a lesser extent of total Cholesterol and LDL), with a significant association of the use of Protease Inhibitors (PIs) and CD4 levels lower than 200/mm3.

School of Medicine, National University of Cordoba, has been raising warning fl ags regarding the effects of global warming on public health, since it stimulates the advance of the epidemiologic boundary of vector transmitted diseases; leishmaniasis is an example of this statement. This zoonosis has been diagnosed in a patient from Unquillo, a mountainous region, little more than 20 km away from the capital of Cordoba, Argentina. The diagnosis has been checked with tissue biopsies, undoubtedly through parasite observation. Deforestation for agriculture and wood production, the generation of closed neighborhoods in the surroundings of cities, the migration of people coming from endemic areas and the global increase of temperatures are the factors which favor the new settlements of this pathology.8 This disease has a great impact on health and its vector has to be fought against through permanent health programs. Cutaneous leishmaniasis is greatly spread in America and representations can be found since pre-Columbian times in pottery and anthropomorphic huacos showing lesions corresponding to this pathology.1, 7, 8 The etiologic agent is a parasite transmitted by a small insect, Lutzomyia; it produces chronic ulcers and mutilation due to the destruction of nose and larynx cartilages. It is a priority to inform about the emergency of the disease, generate preventive actions of health promotion and let all the health team know about the existence of the disease in our setting.1, 7, 8

In the face of the outbreak of Ebola Virus Disease (EVD) that took place in the African continent and the incidence of cases outside the primary focus location, it is necessary to prepare and communicate adequately the health team regarding the clinical management of the patient as well as safe working procedures and management of hazardous waste (due to its infectious characteristic) generated from patient care. Training and risk communication are key elements for the health team. The objective of this work is to review and develop a series of recommendations for the safe and comprehensive management of waste from patients with EVD, on the basis of world experiences on the topic and internal criteria for management of medical waste of health institutions. Another objective is to identify aspects regarding the communication of the risk of handling this waste, in order to reach safe standards that will reduce the impact of the disease on the health team. Results are presented in two sections; one referred to how to communicate and the other to what to communicate. Regarding how to communicate the risk of handling waste in the health team, the stages of a plan are detailed. With respect to the content, we present recommendations that can be taken as the basis for guidelines about internal management of medical waste in institutions treating cases of EVD.

Authors: Rodríguez González Nicolás
Published: October 2024

In this work we present the results of a research regarding the meaning given to health promotion in the northeast of Montevideo. The study included Doctors from primary health care level and social actors from the area. Only the information related to health staff is developed in this work. In a qualitative approach, ten deep interviews and a discussion group were carried out with doctors. From the main results, the multiple significances and the heterogeneity in health promotion practices are highlighted. In turn, significances towards what is established were visualized, where the characteristic is the centrality in the illness and the individual in the cure; articulated with transforming significances oriented towards community participation and organization. Both universes of significances are combined and appear interrelated with the medical staff.
Análisis de la accesibilidad geográfica en la atención primaria de la salud: estudio aplicado en los Centros Regionales de Referencias del Gran Resistencia (Chaco, Argentina)
Authors: Ponce Blanca Elizabeth
Published: October 2024

The objective of this research is to study the geographic accessibility barriers in primary health care. To do this, the study was centered in the four Reference Regional Centers (RRC) that exist in Gran Resistencia; former neighborhood Health Centers which today offer a greater complexity level. Geographic accessibility is defined as how easy it is for the patients to use the service at the time they want or need it. The main source of information for this research is a survey carried out in the year 2010 to a sample of the population who goes to the RRCs. As main significant conclusions we can mention that the distances the users have to cover, the means of transport they have to use as well as road conditions represent a barrier and place their health at risk.
Diferentes obstáculos financieros en la consulta con profesionales de la Salud en Argentina
Authors: Ballesteros Matías Salvador
Published: October 2024

In this article we analyze the different financial obstacles the population has to go through in order to have access to a doctor, a dentist, a psychologist or a psychiatrist in urban areas in Argentina. The work is based on a Survey about Use and Expenditure on Health Services carried out in the year 2010 together by CEDOP (UBA) and DEIS (MSAL). As a result, we see that there are differential financial obstacles to make appointments with different health professionals. Those who see a dentist, a psychologist or a psychiatrist have to spend more of their “own” money than those who see a doctor. The main reason explaining this differential expenditure is the different coverage the Argentine system provides for the appointments with professionals.

The Human Papillomavirus (HPV) vaccine is presented as a primary preventive measure of cervical cancer (CC), the second cause of women deaths in the world. This vaccine generates such social dichotomy that makes us consider whether its administration is really necessary. The possible causes of this controversy are developed in this article, with the aim of helping to make an informed decision about its administration. Available vaccines are reviewed, as well as use recommendations and controversy regarding effectiveness, security, required doses, prevention efficiency and people’s participation. HPV vaccines offer a promising approach to prevent cervical cancer and conditions associated with these viruses, but they do not replace other prevention strategies since they do not protect against all HPV types.
Covid-19 Pandemisi Bağlamında Risk Toplumunda Ev ve İktidar İlişkileri

Mekân, insanların eylemleri, inanç dünyaları, sosyal ilişkileri gibi önemli sosyal ve kültürel kodlarıyla süslenerek inşa edilmektedir. Mekânlar sadece birer binadan veya taşlardan oluşan maddi varlıklar değildir, aynı zamanda toplumların kolektif bilincini taşıyan kültürel unsurları da barındırmaktadır. Özellikle bu manevi unsurları bünyesinde barındıran temel mekânlardan biri de evlerdir. Sosyo-mekânsal bir unsur olarak evler, her coğrafyanın ihtiyaç ve şartlarına göre şekillenmektedir. Her ne kadar şekilsel olarak değişse de hepsinin ortak özelliği, maddi veya manevi duygusallığın yoğun olarak yaşandığı mekânlar olmasıdır. Bu benzerlikler özellikle risk toplumunda daha belirgin bir biçimde görülmektedir. Her şeyden önce korku kültüründe veya risk toplumunda en güvenlikli mekânlar evler olmuştur. Fakat evler, hiçbir zaman toplumsal hayatta ve kamusal mekânlarda bireyleri tahakküm altına alan iktidar ilişkilerinden bağımsız bir okumaya tabi tutulamaz. Özellikle iktidarın söylem ve pratiklerle, hayatın her alana müdahalesi “ev” içerisindeki ilişkilere de yansımaktadır. Foucault’un analizinde olduğu gibi modern dönemde iktidar makro yapılarda olduğu kadar en basit ilişkilerde dahi bulunarak mikro yapılarda da varlığını sürdürmektedir. Bütün bunlardan hareketle yapılmak istenen bu çalışma ev ve iktidar ilişkilerini detaylı bir şekilde analiz etmeyi amaçlamaktadır ve özgün bir konu olması nedeniyle literatüre önemli bir katkı sunacağı düşünülmektedir.
